ボート天気予報とは?

ボート天気予報とは、水上での一日を実際に左右する条件を中心にまとめた海洋気象予報です。すなわち、風速と風向波高と周期、そして全体的な海況です。陸上の天気予報と違い、雨が降るかどうかではなく、あなたの船にとって水上が安全で快適かどうかを伝えます。

難しいのは、それを読み解くことです。ノット、有義波高、秒単位のうねりの周期といった生の海洋データを解釈するには経験が要ります。SeaLegs AI がその解釈を代わりに行い、数値をスポットごと・日ごとの一つの正直な評価へと変換します。

GO

ほとんどのプレジャーボートにとって好条件。弱~中程度の風、穏やかな海、快適なタイミングです。

CAUTION

際どい状況。能力のある船と経験豊富なボーターなら対応可能ですが、まずは風と波のタイミングを確認しましょう。

NO-GO

小型船にとって危険。切り立った波や短周期の波、強い風が予想されます。出航は延期するのが賢明です。

Hudson Canyon Boating Forecast

Live GO / CAUTION / NO-GO conditions for Hudson Canyon — the largest submarine canyon on the U.S. East Coast, roughly 70–100 nautical miles offshore of New York Harbor and a premier run for tuna, marlin, and mahi. A long offshore run where wind against current and swell period decide the day.

📋 Latest outlook: Rough seas early week, calm returns Wednesday

NO-GOMon Sep 14

Winds run 5-19 knots NNW with gusts to 27 knots, and steep wind-wave chop builds through midday into evening as seas hold 2.8-5 feet at just 5-second periods from the NNE. That short period makes for choppy, uncomfortable seas most of the day - not a safe day to be out.

NO-GOTue Sep 15

Winds are steadier at 7-17 knots NE, but waves stay dangerous through the morning and midday, running 3.1-5 feet at 5-second periods from the NE - a choppy, punchy sea state. Conditions only ease late in the day, but low confidence keeps this a NO-GO overall.

GOWed Sep 16

A great day on the water: light 1-6 knots ENE winds with gusts under 11 knots and gentle 2.6-3 feet seas at 6-second periods from the east. Waves stay good all day, with the smoothest, most organized conditions from early morning through midday.

Wednesday 1:00 AM to 12:00 PM is the pick, with light 4 knots ENE winds and gentle 3 feet seas at 6-second periods from the east making for smooth, organized conditions.

Islamorada Hump Boating Forecast

Live GO / CAUTION / NO-GO conditions for Islamorada Hump — “The Hump” off Islamorada in the Florida Keys — an underwater seamount that rises sharply into the Gulf Stream and stacks up blackfin tuna, amberjack, and pelagics. Strong current over the structure makes sea state and wind direction the difference between a comfortable troll and a rough ride.

📋 Latest outlook: Calm Monday, but choppy seas force NO-GO Tue-Wed

GOMon Sep 14

A great day on the water with light 1-9 knots ESE winds (gusts to 12 knots) and gentle 0.6-1.1 feet seas at 3-second periods from the ESE. Good conditions hold all day, making this the clear pick of the week.

NO-GOTue Sep 15

Winds pick up to 10-15 knots E with gusts to 22 knots, and seas build to 1.3-3.2 feet at just 3-second periods from the E, creating a steep, choppy wind-driven sea that turns rough by evening. Low confidence in the forecast adds risk, so this is a NO-GO despite decent waves earlier in the day.

NO-GOWed Sep 16

11-14 knots ENE winds gust to a stiff 26 knots, kicking up 2.7-3.4 feet seas at short 4-second periods from the ENE for a steep, uncomfortable wind-wave chop overnight and evening. Add 0.33in of rain and low confidence, and this day stays NO-GO despite a fair midday window.

Monday all day is the pick, with light 1-9 knots ESE winds and small 0.6-1.1 feet seas at 3-second periods from the ESE making for smooth, easy conditions.

Cortez Bank Boating Forecast

Live GO / CAUTION / NO-GO conditions for Cortez Bank — a remote, shallow seamount about 100 miles off San Diego known for world-class fishing and giant open-ocean swell at Bishop Rock. Fully exposed offshore, so a careful read of swell height and period is essential before making the crossing.

📋 Latest outlook: Unsafe seas all three days; large swell keeps this a no-go

NO-GOMon Sep 14

No-go all day: 7-9 foot WNW swell at 7-second periods combines with 14-21 knot NW winds gusting to 28 knots. Wave heights alone make this too dangerous for recreational boating, and model confidence is low.

NO-GOTue Sep 15

No-go despite lighter 9-14 knot WNW winds. Persistent 6-7 foot WNW swell at 8-second periods keeps wave risk too high all day, and model confidence in wind remains low.

NO-GOWed Sep 16

Improving but still a no-go: winds are light (8-13 knots WNW) but swell holds in the 4.7-6.0 foot range at 8-9 second periods most of the day. Only late evening approaches acceptable, and low model confidence keeps this a caution/no-go call.

Persistent 5-9 foot WNW swell at 7-9 second periods dominates the entire period, only easing slightly by midweek, while wind stays manageable throughout. Model confidence is low across the board (44-52%) due to diverging wind speed/gust forecasts, but wave heights remain large and consistent enough to keep every day unsafe for recreational boating.

FAD Buoy 1 Boating Forecast

Live GO / CAUTION / NO-GO conditions for FAD Buoy 1 — a fish aggregating device anchored in open water that concentrates mahi-mahi, tuna, and wahoo around it. Open-ocean positioning means conditions can shift fast, so check the latest wind and wave outlook before running out.

📋 Latest outlook: Calm Mon-Tue, but Wed brings dangerous steep chop

CAUTIONMon Sep 14

Light 2-7 knots NW winds and calm 0.7-1.0 feet seas at 3-4 second periods all day Monday. A favorable window for boating, though forecast confidence is only moderate.

CAUTIONTue Sep 15

Light-to-moderate 4-14 knots winds shifting from north to east through Tuesday, with seas staying under 2 feet most of the day. Evening winds and gusts increase, so plan for a cautious, well-timed outing given low forecast confidence.

NO-GOWed Sep 16

Dangerous conditions Wednesday: east winds gusting 24-28 knots build steep 4-6 feet seas at just 4-5 second periods. Rough, punishing chop persists most of the day - stay off the water.

Monday and Tuesday offer light winds and small, well-organized seas, though model confidence is low on both days due to disagreement on wind speed and gusts. Wednesday turns hazardous as easterly winds build past 20 knots with gusts into the high 20s, whipping up steep, short-period seas near 5-6 feet that make for an unsafe, choppy ride - avoid boating that day.

San Jaime Bank Boating Forecast

Live GO / CAUTION / NO-GO conditions for San Jaime Bank — a deep bluewater bank about 20 nautical miles west-southwest of Cabo San Lucas, rising from the Tinaje Trough where upwelling stacks bait and holds blue and black marlin and yellowfin tuna. Open Pacific water, so read swell period and wind against current before the crossing.

📋 Latest outlook: Light winds all week, but caution flagged for building SW swell

CAUTIONMon Sep 14

Light NNW winds under 10 knots and organized 4.1 feet SW swell at 8-9 seconds make for a pleasant-looking Monday, but low model confidence (56%) on wind and gusts means conditions should be reconfirmed before heading out. Best window is midday to afternoon.

CAUTIONTue Sep 15

Tuesday's winds stay light under 6 knots, and the SW swell holds a comfortable 10-second period through most of the day, but it builds to nearly 4.8 feet by evening pushing conditions into caution after 8:00 PM. Model confidence is moderate (61%), so keep plans flexible and finish up before dark.

CAUTIONWed Sep 16

Light winds under 8 knots continue Wednesday, but the SW swell has grown to 4.8-4.9 feet at 10-11 second periods, keeping wave conditions in caution all day. Model confidence is moderate (62%), so approach with care despite the calm-looking wind forecast.

Wind stays light across all three days, but confidence is only moderate (56-62%) and the SW swell steadily builds from 4.1 ft to 4.9 ft, keeping every day at a CAUTION level despite calm breezes. Wave period is generally comfortable, but model spread on gusts and period keeps the safety margin thin.

Baltimore Canyon Boating Forecast

Live GO / CAUTION / NO-GO conditions for Baltimore Canyon — a premier Mid-Atlantic canyon at the shelf edge about 60 miles off Ocean City and Cape May, where blue and white marlin and bigeye and yellowfin tuna set up on the warm shelf-break edge. A genuine offshore run, so weight swell period as heavily as height.

📋 Latest outlook: Choppy seas Mon-Tue keep boats in; Wed offers calm relief

NO-GOMon Sep 14

Winds run 6-21 knots NNW with gusts to 29 knots, and while mornings look calmer, waves build to 3.0-5.2 feet at just 5-second periods from the ENE for a steep, choppy chop most of the day. Low confidence and rough afternoon seas make this a NO-GO.

NO-GOTue Sep 15

Winds ease into the good range for most of the day at 10-19 knots NE, but seas stay rough, holding at 3.9-5.3 feet on short 5-second periods from the NE well into the afternoon. Combined with low forecast confidence, conditions add up to a NO-GO.

CAUTIONWed Sep 16

A big improvement: winds stay light all day at 4-9 knots ENE with gusts only to 13 knots, and waves settle to 3.0-3.8 feet at a more organized 6-second period from the east. Only a brief early-morning wave hiccup keeps this from a full green light, so it's CAUTION overall, best late morning onward.

Wednesday 1:00 AM to 11:00 AM is the pick, with light 4-9 knots ENE winds and manageable 3.0-3.8 feet seas at 6-second periods from the east.

38.1500, -73.8500 · Updated Mon Sep 14, 2026 · Full Baltimore Canyon forecast →

Sandy Hook Boating Forecast

Live GO / CAUTION / NO-GO conditions for Sandy Hook — the six-mile spit at the entrance to Lower New York Bay — the northern gateway to the Jersey Shore, where harbor current meets ocean swell at the tip and Raritan Bay offers a protected fallback when the oceanfront blows out.

📋 Latest outlook: Choppy midweek seas easing to a calm Wednesday

CAUTIONMon Sep 14

Winds run 6-13 knots NNW with gusts to 21 knots, and while waves average 1.2-1.9 feet at 4-second periods from the NNE, low forecast confidence and steep wind-wave chop persisting most of the day call for caution - the short-period chop can feel choppier than the numbers suggest.

CAUTIONTue Sep 15

Light 4-10 knots ENE winds and 1.3-1.9 feet seas at 4 seconds from the ENE look manageable, but a few hours of steep wind-wave chop and lower confidence keep this a caution day; conditions improve noticeably by afternoon into evening.

GOWed Sep 16

The pick of the week: light 2-10 knots SSW winds, gusts only to 16 knots, and organized 1.1-1.4 feet seas at 5-second periods from the ESE make for a comfortable, well-behaved sea all day.

Wednesday 12:00 AM to 11:00 PM offers the best conditions, with light 2-10 knots SSW winds and gentle 1.1-1.4 feet seas at 5-second periods from the east-southeast.

40.4875, -73.9933 · Updated Mon Sep 14, 2026 · Full Sandy Hook forecast →

Lake Erie Boating Forecast

Live GO / CAUTION / NO-GO conditions for Lake Erie — the shallowest of the Great Lakes, where a westerly wind gets the full long axis to work with and a shallow basin turns that fetch into short, steep sea faster than depth-blessed water ever would.

📋 Latest outlook: Rough Monday chop; midweek settles but stays low-confidence

NO-GOMon Sep 14

Steep, choppy 0.8-4 feet seas at 3-second periods from the north build with 15 knots NNE winds gusting to 26 knots, creating very rough wind-wave chop through midday, easing only slightly by afternoon. Unsafe, uncomfortable conditions and low confidence make this a NO-GO day.

CAUTIONTue Sep 15

Winds stay light at 7-10 knots SSE with gusts to 18 knots, and seas are small at 1.0-1.8 feet, but short 2-second periods from the south mean a choppy, wind-driven surface. Low forecast confidence keeps this a CAUTION day, so watch conditions closely before heading out.

CAUTIONWed Sep 16

Light 3-9 knots SSW winds and small 0.4-1.5 feet seas at 2-second periods from the WSW look favorable, with a brief midday shower possible. Confidence is only moderate, so this stays a CAUTION day despite the calm-looking numbers - best used cautiously during the mid-morning to afternoon window.

Wednesday 4:00 AM to 3:00 PM is the pick, with light 4-5 knots SSW winds and calm 1-foot seas at 2-second periods from the WSW.

41.9000, -81.4000 · Updated Mon Sep 14, 2026 · Full Lake Erie forecast →

Lake Michigan Boating Forecast

Live GO / CAUTION / NO-GO conditions for Lake Michigan — deep, cold, and 300 miles from end to end — a northerly gets the whole axis to work with, and the water stays cold enough to matter long after the air has warmed up.

📋 Latest outlook: Steep, choppy seas keep all three days off-limits

NO-GOMon Sep 14

SSE winds to 16 knots with gusts to 26 knots stir up very steep, short-period 3-second wind-wave chop most of the day, making for an uncomfortable, unsafe ride despite a brief calmer stretch midday. Overall a NO-GO with low confidence in the forecast.

NO-GOTue Sep 15

A rough day: SSW winds gusting to 34 knots combine with 2-7 foot SSW seas at just 4-second periods, producing very steep wind-wave chop for most of the day. Waves stay bad from midnight through late afternoon before easing slightly in the evening. Unsafe conditions — a clear NO-GO.

NO-GOWed Sep 16

Lighter NE winds near 4-12 knots and small 1-2 foot N seas look tempting, but the forecast carries low confidence and a brief steep, choppy patch around 4:00 AM keeps this a cautious NO-GO overall. Best-case window would be mid-morning to evening, but conditions aren't confirmed safe.

No acceptable window exists this period; even Wednesday's calmer wind can't offset the borderline caution rating, so all days are best avoided for boating.

44.0000, -86.6000 · Updated Mon Sep 14, 2026 · Full Lake Michigan forecast →

Ocean City Inlet Boating Forecast

Live GO / CAUTION / NO-GO conditions for Ocean City Inlet — the jettied cut between Fenwick Island and Assateague that the 1933 hurricane opened — the single gate every Ocean City boat passes through, with the Jackspot 23 miles out and the Baltimore and Poor Man's canyons at 60.

📋 Latest outlook: Choppy start, cross-seas linger; Wednesday finally clears up

NO-GOMon Sep 14

Winds stay light at 4-11 knots NNW with gusts to 20 knots, but midday brings a steep wind-wave chop layered over the 5-second ENE swell, making the sea state uncomfortable and unpredictable for about 12 hours. Low forecast confidence adds risk, so this is a NO-GO day.

NO-GOTue Sep 15

Light 4-8 knots NE winds mask an unsettled sea underneath, with 2.8-3.7 feet waves at 5-second periods from the ENE creating a choppy, confused ride. Confidence remains low at 52%, so despite calm-looking wind numbers, this stays a NO-GO day.

GOWed Sep 16

Conditions turn excellent with light 2-6 knots easterly winds, gentle gusts to 12 knots, and well-organized 2.4-2.9 feet seas at 6-second periods from the east all day. High 75% confidence backs up a clean, comfortable GO day for boating.

Wednesday 12:00 AM to 11:00 AM is the pick, with light 2-3 knots easterly winds and organized 2.8-2.9 feet seas at 6-second periods from the east.

San Juan Harbor Boating Forecast

Live GO / CAUTION / NO-GO conditions for San Juan Harbor — The narrowest shelf of any port we cover — thousands of feet of water within a few miles of the harbour mouth.

📋 Latest outlook: Light winds but low-confidence forecasts keep it CAUTION all week

CAUTIONMon Sep 14

Winds run 5-14 knots ESE with gusts to 21 knots and seas 1.8-2.3 feet at 6-second periods from the NE - manageable on paper, but a period of steeper wind-driven chop develops for about 4 hours and forecast confidence is only 36%, so stay alert and flexible on timing.

CAUTIONTue Sep 15

A similar setup with 4-13 knots ESE winds, gusts to 20 knots, and 1.8-2.2 feet seas at 5-second periods from the NE keeps things generally comfortable, but confidence is just 48% and a bit of rain is possible, so treat this as a caution day and reassess close to departure.

CAUTIONWed Sep 16

Winds pick up slightly to 5-15 knots E with gusts to 24 knots, and seas run 1.8-2.5 feet at 5-second periods from the ENE - a bit choppier and gustier than earlier in the week. With only 41% confidence, conditions could shift, so plan for caution rather than a clean go.

Sunday night into Monday morning (9:00 PM to 8:00 AM) offers the calmest stretch, with 6 knots ESE winds and 2 feet seas, though forecast confidence is low so double-check conditions before heading out.

18.4908, -66.1556 · Updated Mon Sep 14, 2026 · Full San Juan Harbor forecast →

Cabo San Lucas Boating Forecast

Live GO / CAUTION / NO-GO conditions for Cabo San Lucas — the harbour mouth at Land's End, where the Pacific meets the Sea of Cortez and every Cabo trip starts and finishes. One side of the point can be glassy while the other is lumpy, so this is the departure read before you choose which way to turn.

📋 Latest outlook: Three straight GO days with light winds and long-period swell

GOMon Sep 14

Light winds (under 9 knots) and smooth 3.1-3.4 feet seas at 9-10 second periods make for an excellent Monday. Best conditions arrive in the evening (5:00 PM-9:00 PM MST) as winds drop to near-calm.

GOTue Sep 15

Tuesday is the calmest day, with winds mostly 2-6 knots and smooth 3.4-3.7 feet seas at 11-12 second periods. Best conditions are overnight through mid-morning; a light afternoon breeze from the SSW is the only minor change.

GOWed Sep 16

Wednesday stays favorable with winds up to 8 knots and smooth 3.7-3.9 feet seas at 11-12 second periods. Early morning (before 8:00 AM MST) is calmest; afternoon brings a bit more breeze with gusts to 15 knots from the SSW/SW.

All three days show excellent, calm boating conditions with light winds under 10 knots and long-period 9-12 second swells from the south/southwest producing smooth, well-organized seas. Confidence is moderate (72-74%), mainly due to some gust and wave-period model disagreement, but the overall picture is consistently favorable.

San Diego Boating Forecast

Live GO / CAUTION / NO-GO conditions for San Diego — the open coastal waters off Point Loma, where WNW groundswell, summer south swell, and the afternoon sea breeze decide the day. Mornings are usually the calm half — plan the return leg, not just the run out.

📋 Latest outlook: Choppy Monday, calmer but low-confidence midweek window

NO-GOMon Sep 14

Winds stay light at 4-9 knots WSW, but seas of 4.3-5.2 feet at 8-second periods from the west turn choppy through midday and afternoon (caution hours 1:00 AM to 5:00 PM), with only very low forecast confidence. This combination makes conditions unsafe to plan around today - a NO-GO.

CAUTIONTue Sep 15

Winds are light all day, 3-8 knots SW, and seas ease to 3.9-4.3 feet at 8-second periods from the west, staying favorable through all hours. Confidence is low at just 12%, so conditions look good on paper but treat timing with caution and reconfirm closer to the day.

CAUTIONWed Sep 16

A gentle day with 2-9 knots W winds and 3.4-3.9 feet seas at a comfortable 10-second period from the WSW, good waves all day. Confidence is still modest at 25%, so it's rated CAUTION - promising conditions, but double-check the updated forecast before heading out.

Tuesday evening into Wednesday morning (8:00 PM to 8:00 AM) offers the calmest stretch, with light 3-4 knots SW-W winds and organized 3.9-4 feet seas at 8-10 second periods.

Destin Pass Boating Forecast

Live GO / CAUTION / NO-GO conditions for Destin Pass — the East Pass cut between Holiday Isle and Santa Rosa Island, where Choctawhatchee Bay meets the Gulf and every charter, party boat and private boat out of Destin Harbor crosses twice a day.

📋 Latest outlook: Calm Mon-Tue boating, Wed gusty afternoon chop

GOMon Sep 14

A great day on the water with light 1-5 knots northwest winds (gusts to 12 knots) and small 0.6-0.9 feet seas at 3-second periods from the southwest. Visibility is excellent all day, making any hour a good time to head out.

GOTue Sep 15

Another favorable day with gentle 2-6 knots east-northeast winds (gusts to 15 knots) and modest 0.6-0.8 feet seas at 4-second periods from the south. Clear visibility and calm seas all day keep this a solid, comfortable outing.

CAUTIONWed Sep 16

Use caution: winds pick up to 4-10 knots east-northeast with gusts to 22 knots, and seas build to 1.1-2.3 feet at a short 3-second period from the east-southeast, creating a steeper, choppier ride. Confidence is lower too, so plan carefully and stay alert to changing conditions.

Monday 12:00 AM to 11:00 AM is the top pick, with light 1-5 knots northwest winds and gentle 0.6-0.9 feet seas at 3-second periods from the southwest making for easy, comfortable conditions.

Auckland / Hauraki Gulf Boating Forecast

Live GO / CAUTION / NO-GO conditions for Auckland / Hauraki Gulf — Auckland's inner sea, screened from the open Pacific by Great Barrier Island and the Coromandel Peninsula. The shelter is directional — westerlies are short-fetch, but a sustained northeast runs straight down the gap and the swell arrives with far less to stop it.

📋 Latest outlook: Light winds all week; Mon-Tue caution on low forecast confidence

CAUTIONMon Sep 14

Light SSW winds (7-11 kt, gusts to 17 kt) and small sub-2 ft seas look comfortable, but only 40% forecast confidence means real conditions could differ - stay cautious and monitor updates. Evening after 9:00 PM offers the calmest window.

CAUTIONTue Sep 15

Light winds (3-7 kt) shifting from S to SE to SW and seas under 1 ft look pleasant, but only 49% model confidence with diverging wind/wave direction data keeps this a caution day. Midday hours (10:00 AM-3:00 PM) show the best wave organization.

GOWed Sep 16

Excellent conditions with winds under 4 knots (WNW/NW) and seas below 0.7 ft all day. High 69% model confidence and strong agreement on wind speed and wave height make this the week's best and most reliable GO day.

Winds stay light (under 11 knots) and seas small throughout the period, but Monday and Tuesday carry low model confidence due to diverging wind and wave-period forecasts, warranting a cautious approach despite otherwise favorable numbers. Wednesday sees the forecast models converge nicely, supporting a clean GO day with the calmest winds and seas of the week.

Tauranga Boating Forecast

Live GO / CAUTION / NO-GO conditions for Tauranga — the Bay of Plenty outside Tauranga, where Matakana Island splits the harbour into two entrances. Entrance flow runs hard, and swell against an outgoing tide is what stands the bar up — check the bar itself before committing.

📋 Latest outlook: Light winds all week; Monday & Wednesday need cross-swell caution

CAUTIONMon Sep 14

Light SW winds (2-7 knots) and small waves, but a confused cross-sea develops midday (12:00 PM-4:00 PM) as a shifting wind-wave crosses the NE swell, causing uncomfortable motion. Low model confidence adds uncertainty. Evening after 7:00 PM is calmer and more comfortable.

GOTue Sep 15

Tuesday offers the best conditions of the week: light 1-5 knots winds and small, consistent 0.7-1.0 feet NE waves at 5-8 second periods all day. High model agreement on wave direction and height makes this the most reliable, comfortable day to be on the water.

CAUTIONWed Sep 16

Light-to-moderate W/WSW winds (2-9 knots) with small waves, but afternoon (12:00 PM-6:00 PM) brings a confused cross-sea as a short-period WNW wind-wave crosses the N/NE swell, creating choppy, uncomfortable conditions with gusts to 20 knots. Morning hours are calmer and preferred.

Wind speeds stay light (under 10 knots) and wave heights remain under 1.5 feet across all three days, but Monday and Wednesday both feature a confused cross-sea from mismatched swell and wind-wave directions that creates awkward, uncomfortable motion despite the otherwise calm numbers. Tuesday stands out as the cleanest day with the best model agreement and a single, consistent NE wave train.

Moreton Bay Boating Forecast

Live GO / CAUTION / NO-GO conditions for Moreton Bay — Brisbane's sheltered water, screened from the Coral Sea by Moreton and North Stradbroke Islands. The bay is shallow, so a fresh southeasterly builds a short steep chop out of proportion to the wind — and the shelter ends where the islands do.

📋 Latest outlook: Calm Mon-Tue turns rough Wed; overall NO-GO by midweek

GOMon Sep 14

Excellent conditions all day Monday with light 4-8 knots east winds and small 1.2-1.7 feet seas at 4-5 second periods. Best window is 5:00 PM-9:00 PM when winds drop to just 4 knots. A great day to be on the water.

CAUTIONTue Sep 15

Calm morning with light 3-7 knots NE winds and smooth 1.0-1.1 feet seas, but from mid-afternoon a steep wind-wave chop develops at just 3-second periods riding atop the swell. Plan to be off the water by early afternoon to avoid the choppier evening conditions.

NO-GOWed Sep 16

Dangerous conditions develop from mid-morning as south-southeast winds surge to 17-20 knots with gusts over 40 knots, building steep 4-5 feet seas at only 3-4 second periods. Low forecast confidence adds uncertainty, but conditions look unsafe for boating - stay ashore.

Monday and Tuesday offer light winds and small, well-organized seas making for excellent boating conditions, but Tuesday afternoon starts building a steeper wind-wave chop. Wednesday brings a strong southerly wind event with gusts over 35 knots and seas building to near 5 feet at short 3-4 second periods, creating dangerous, unsafe conditions for recreational vessels. Given the deterioration into Wednesday and low model confidence that day, the overall multi-day outlook is NO-GO.

Sydney Boating Forecast

Live GO / CAUTION / NO-GO conditions for Sydney — Sydney's exposed coastal water, where the pattern to respect from October to February is the southerly buster — an abrupt afternoon southerly change that can gust over 40 knots within minutes of arriving.

📋 Latest outlook: Deteriorating seas midweek make this a NO-GO stretch overall

CAUTIONMon Sep 14

Early morning brings a brief confused cross-sea (SSE swell vs NE wind-wave) causing awkward chop until around 3:00 AM. After that, light 3-8 knot north winds and smooth 4-5 foot seas at 7-8 second periods make for a solid boating day.

NO-GOTue Sep 15

Calm early hours with light winds and small seas give way to a dangerous evening: south winds gust to 28 knots and seas build from 3.4 feet to 7.5 feet as a confused cross-sea develops between NE swell and SSE wind-wave. Low model confidence adds uncertainty - avoid this day.

NO-GOWed Sep 16

Dangerous all day: south seas build to nearly 11 feet at 7-8 second periods with south-southwest winds gusting up to 37 knots. No safe window exists - this is a full NO-GO day.

Monday offers light north winds and manageable easterly swell, but a brief early cross-sea and firming NE breeze keep it in caution territory. Tuesday's calm daytime hours give way to rapidly building south swell by evening, and Wednesday brings dangerous 9-11 foot south seas with gale-force gusts, making the back half of the week unsuitable for boating.

Live GO / CAUTION / NO-GO conditions for Cook Strait — the exposed water south of Wellington Harbour, where the gap between the North and South Islands funnels and accelerates the weather. Strong tidal streams mean wind against tide, not wind speed alone, is what decides the day.

📋 Latest outlook: Persistent large swell and rising gales rule out boating all week

NO-GOMon Sep 14

Light 4-14 knot N/NNW winds all day, but a large 6-7.7 feet south swell at 9-11s periods makes this a NO-GO despite calm winds. Swell is long-period but simply too big for recreational boating. Low confidence (29%) adds uncertainty.

NO-GOTue Sep 15

Winds build from 15 to 26 knots N with gusts to 36 knots, and a confused cross-sea develops as S swell crosses newly arriving WNW/NNW wind-waves. Steep 5.8-6.4 feet seas at shortening 5-6s periods make this a NO-GO. Low confidence (41%) with gusts diverging in all models.

NO-GOWed Sep 16

Gale-force 25-30 knot NNW winds with gusts to 40 knots combine with steep 6-7.3 feet seas at just 5-second periods from the NNW. This produces dangerous, breaking chop - a clear NO-GO for all recreational boating. Confidence is low (41%) but the hazardous wave/wind combination is well supported.

This entire three-day window is a NO-GO, driven by a large long-period south swell colliding with building north winds on Monday, then a full gale developing Tuesday into Wednesday with steep, confused seas. Confidence is low across all three days due to diverging wind and gust model guidance, but the underlying hazard - large or steep waves paired with strengthening wind - is consistent enough to keep all vessels in port.

Perth Boating Forecast

Live GO / CAUTION / NO-GO conditions for Perth — Perth's coastal water, run on a clock by the Fremantle Doctor — the 15–20 knot southwesterly sea breeze that fills in most warm-season afternoons. Mornings are usually the calm half of the day.

📋 Latest outlook: Persistent heavy SW swell keeps all three days a no-go

NO-GOMon Sep 14

Calm morning winds give way to a building southwest wind-wave layered on a 7 ft SW swell, with gusts to 25 knots by evening steepening the sea for about 4 hours. Entire day remains NO-GO due to this chop.

NO-GOTue Sep 15

Southeast winds to 18 knots with gusts to 24 knots stack steep chop on a 6 ft SW swell for about 8 hours through midday and evening. Low model confidence adds uncertainty, but conditions stay NO-GO all day.

NO-GOWed Sep 16

Wednesday improves with lighter 8-13 knots easterly winds and swell easing to under 4 ft by afternoon, but a 3-hour steep chop window overnight and low confidence keep the day at NO-GO. Afternoon 2-6 PM looks best but isn't a clean go.

A large, long-period southwest swell (roughly 5.5-7 ft at 12-13 seconds) dominates all three days, and while the swell itself is long-period, building wind and confused sea-state layer steep wind-driven chop on top of it during key hours, pushing every day into NO-GO territory. Confidence is low-to-moderate across the period as wind speed and direction diverge significantly between model runs, adding uncertainty to the exact timing of the roughest chop.

Napier Boating Forecast

Live GO / CAUTION / NO-GO conditions for Napier — the open western shore of Hawke Bay, where boats cross exposed water from Napier and Ahuriri to the snapper and kingfish grounds. East and southeast swell drives the day; an offshore westerly flattens it right down.

📋 Latest outlook: Three straight calm, boater-friendly days with light winds

GOMon Sep 14

Light 1-7 knots winds (NW early, shifting E by afternoon) and small 2.2-2.4 feet seas at 7-8 second periods from the SSE make for an easy, comfortable Monday. A brief gust spike to 15 knots mid-afternoon is the only bump. Great day to be on the water.

GOTue Sep 15

Light 1-7 knots winds rotating from NW to E through the day and steady 2.4 feet SE seas at 7-8 second periods keep Tuesday calm and pleasant. A modest gust bump to 14 knots arrives early afternoon but nothing concerning. Good confidence supports a GO all day.

GOWed Sep 16

Wednesday's breeziest stretch is overnight into early morning with 8-10 knots WNW wind and gusts to 16-17 knots, easing to a light 1-5 knots by afternoon. Seas stay comfortable all day at 2.2-2.4 feet with 8-9 second SE periods. A solid GO day, best after mid-morning once winds ease.

A settled pattern holds through Monday to Wednesday with light winds and small, well-organized seas at every hour. Confidence is moderate (61-71%) due to some gust and wave-period model disagreement, but the overall wind and wave picture is consistent enough to call all three days GO.

Kaikōura Boating Forecast

Live GO / CAUTION / NO-GO conditions for Kaikōura — a coast that sits over a 1,000 m canyon within a few miles of the peninsula. One thing decides a small-boat day here — the southerly, which builds fast and hard and can shut a launch down by mid-morning.

📋 Latest outlook: Light winds all week; Monday's early swell chop eases by GO days

CAUTIONMon Sep 14

Choppy overnight-to-early-morning seas from a lingering 4.5-5 foot south swell ease by 9:00 AM. Winds stay light all day (under 6 knots), making the late morning onward the best time to head out.

GOTue Sep 15

Excellent conditions all day Tuesday: light 1-4 knot winds and a smooth, easing 2.6-4.1 foot SSE swell at 8-second periods. Good boating any time from morning through evening.

GOWed Sep 16

Wednesday offers the smoothest seas of the week - just 1.8-2.6 feet at 8-second periods - with light 2-6 knot winds all day. A comfortable, low-risk day for boating, though gust forecasts carry some uncertainty.

Winds stay light (under 6 knots) through the whole period, but Monday brings a lingering south swell at 4-5 feet that keeps overnight-to-morning seas choppy until mid-morning. Tuesday and Wednesday settle into consistently good wind and wave conditions all day, making them the preferred days to be on the water.

Cairns Boating Forecast

Live GO / CAUTION / NO-GO conditions for Cairns — the gateway to the northern Great Barrier Reef, where almost every trip crosses open water from Trinity Inlet to the outer ribbons. The SE trades set the sea state and decide the run out.

📋 Latest outlook: Three straight GO days with light winds and gentle seas

GOMon Sep 14

Light morning winds (2-6 kt) build to a moderate 9-10 kt southeast breeze by afternoon with gusts to 25 kt, while seas stay a manageable 3-3.6 ft at 6-second periods from the east all day. A good boating day overall, with the calmest conditions early morning and again after 5:00 PM.

GOTue Sep 15

Calm early hours give way to a breezier 8-10 kt southeast wind by midday with gusts to 25 kt, but seas stay a steady 3.6-3.8 ft at 6-second periods from the east. Good boating conditions all day, best in the early morning or after 6:00 PM when winds ease again.

GOWed Sep 16

The lightest day of the week, with winds mostly under 8 kt from the south/southeast and gentle 2.7-3.1 ft seas at 6-second periods from the east. Winds ease to just 2-4 kt by evening, making late afternoon and evening the best time to be out.

Monday through Wednesday offer consistently favorable boating conditions with light winds under 10 knots and manageable 3-4 foot east swell at 6-second periods. Midday hours see a modest breeze pickup with gustier conditions, but wind and wave states stay in the good range throughout. Model confidence is moderate (around 61-62%), mainly due to gust and wind-direction variability, but the overall pattern supports safe outings all three days.

Nelson Boating Forecast

Live GO / CAUTION / NO-GO conditions for Nelson — the sheltered top of Tasman Bay, where the bay geometry and Farewell Spit knock down most open-ocean swell. Wind-driven chop and the afternoon sea breeze, not swell, make the call.

📋 Latest outlook: Calm start Monday, but Wednesday's crossing swell brings caution

GOMon Sep 14

Excellent calm conditions all day Monday with light winds under 8 knots and seas under 1 foot. Great for boating any time - morning, midday, or evening are all favorable.

CAUTIONTue Sep 15

Tuesday looks calm on paper with light winds and small seas, but model confidence is low (47%) with notable disagreement on wind and wave details. Head out with extra caution and check updated forecasts before departing.

CAUTIONWed Sep 16

Wednesday starts calm with light 1-8 knot winds and a manageable 1.0-1.4 feet NNW/WNW swell at 3-second periods through the morning, but seas build steadily through the afternoon to a peak of 3.4 feet by 6:00 PM NZST. During the evening hours around 6:00 PM-7:00 PM NZST, wind-driven chop rides on top of the building NNW swell from a similar northerly sector, steepening and shortening the sea into an uncomfortable, choppy period even though winds themselves stay light. Plan to be off the water or well clear of exposed areas by late afternoon, with the morning through early afternoon offering the more comfortable window.

Monday offers excellent light-wind conditions with tiny, well-organized seas, making it the clear pick for boating this week. Tuesday looks similarly calm on paper but carries low model confidence, so treat it with some caution despite the favorable numbers. Wednesday sees building northerly swell that turns choppy for a few evening hours, so plan around that window.

Port Phillip Bay Boating Forecast

Live GO / CAUTION / NO-GO conditions for Port Phillip Bay — a big enclosed bay off Melbourne with no ocean swell — the sea state is wind-driven chop that stands up short and steep the moment the breeze pipes up. The Rip at the Heads is a separate, serious decision.

📋 Latest outlook: Deteriorating week: light Monday, then rough Tue-Wed chop

CAUTIONMon Sep 14

Light 7-13 knots winds and small 1-1.5 feet seas make Monday the best day of the week, though low model confidence (37%) means a cautious approach is wise. Conditions stay steady and comfortable all day.

NO-GOTue Sep 15

Winds build from 9 knots to 21-22 knots SW with gusts to 30 knots, and seas grow to 4.1 feet at just 3-4 second periods, producing steep, unsafe chop by afternoon. Avoid boating, especially after midday.

NO-GOWed Sep 16

Persistent 16-20 knots S/SSW winds with gusts to 30 knots and steep 1.8-3.8 feet seas at 4-second periods keep Wednesday rough and unsafe most of the day, especially overnight into early morning.

Monday offers light winds and calm seas, but confidence is low due to diverging wind models, so treat it with caution despite favorable numbers. Tuesday and Wednesday bring building southwest to south winds up to 20-22 knots with steep, short-period wind-driven waves that create rough, uncomfortable seas unsuitable for recreational boating.

Bay of Islands Boating Forecast

Live GO / CAUTION / NO-GO conditions for Bay of Islands — roughly 144 islands with glassy inner waters and exposed outer game grounds — the two rarely match. The call is how much easterly swell you'll take once you clear the last island.

📋 Latest outlook: Three straight days of calm winds and gentle seas - great boating

GOMon Sep 14

Great boating conditions all day with light 3-8 kt SW winds and calm 1 foot seas at long 9-12s periods. Any time is a good time to head out on Monday.

GOTue Sep 15

Light winds (1-7 kt) and small 1 foot seas at 8-11s periods make for another comfortable day. A brief afternoon breeze pickup to near 16 kt gusts is the only wrinkle - still easy conditions overall.

GOWed Sep 16

Calm morning with light winds and gentle seas gives way to breezier 7-8 kt NW winds and choppier, shorter-period seas by afternoon/evening. Morning is the smoothest window; afternoon is still boatable but bumpier.

This is an excellent three-day stretch for boating with light winds under 10 knots and small, long-period swell throughout. Confidence is moderate (63-68%) mainly due to some model disagreement on gust magnitude and wind direction shifts, but the overall calm pattern is well supported across all models.

Gold Coast Boating Forecast

Live GO / CAUTION / NO-GO conditions for Gold Coast — where the day is decided at the Seaway bar — a SE groundswell against an ebbing tide turns the entrance dangerous. Read swell period against the tide before the offshore forecast even matters.

📋 Latest outlook: Building southeast swell Wednesday makes for a NO-GO week overall

CAUTIONMon Sep 14

Light winds and organized 4-5 feet seas at 7-8 second periods make Monday look good, but low model confidence (40%) means conditions could shift - proceed with caution, especially outside the calm evening window.

CAUTIONTue Sep 15

Mostly calm with light winds and 3-4 feet seas, but watch for a steep, choppy wind-wave buildup around 3:00-4:00 PM. Best to boat before or after that window.

NO-GOWed Sep 16

Dangerous day: SE swell builds from 3 feet to nearly 11 feet while crossing a SSE wind-wave, creating a confused, unsafe sea state with gusty 25 knot SE winds. Stay off the water all day.

Monday and Tuesday offer light winds and manageable seas, though model confidence is low due to diverging wave height and gust forecasts. Wednesday deteriorates sharply as a growing SE swell collides with a crossing SSE wind-wave, producing a confused, dangerous sea state that builds to nearly 11 feet by evening.

Hervey Bay Boating Forecast

Live GO / CAUTION / NO-GO conditions for Hervey Bay — sheltered in the lee of K'gari (Fraser Island), which walls off the Coral Sea swell, so it's mostly local wind-chop. Strong northerlies down Platypus Bay are the exception.

📋 Latest outlook: Light winds most days, but model uncertainty keeps it a caution

CAUTIONMon Sep 14

Light 8-10 kt SE winds and small 1 ft seas all day, but low 47% confidence with diverging wind data keeps this a caution day. Best conditions arrive 6:00 PM-10:00 PM with winds easing to 5-7 knots.

CAUTIONTue Sep 15

Very light 3-7 kt winds and sub-1 ft seas expected, but only 53% model confidence with significant divergence on wind and wave period. Conditions look easy but could shift - stay alert, especially midday to afternoon.

CAUTIONWed Sep 16

Calm morning with light winds turns rough by afternoon as SE winds jump to 17 kt with 27 kt gusts and seas build to 2.4 ft in a steep, choppy wind-wave pattern. Low 50% confidence adds uncertainty - finish boating before 2:00 PM.

Wind and wave heights look benign on paper all three days, but low confidence readings (47-53%) mean the models disagree on wind direction, gusts, and timing, so treat this as a caution-level forecast requiring on-water verification. Wednesday afternoon also brings a steep wind-wave chop as breeze builds sharply through the day.

Coromandel Boating Forecast

Live GO / CAUTION / NO-GO conditions for Coromandel — snapper country around the Mercury Islands off Whitianga — often sheltered in close, but the open east coast catches easterly swell the moment you push out past the islands.

📋 Latest outlook: Light winds all week, but model uncertainty tempers Mon and Wed

CAUTIONMon Sep 14

Light SW winds build from 5 knots to 10 knots through the day with gusts near 20 knots by afternoon; seas stay under 2 feet but get choppier as periods shorten. Low model confidence (47%) means the forecast could shift, so mornings are the safer bet and it's worth rechecking updates.

GOTue Sep 15

The best day this week - light winds under 6 knots and small, well-organized 1.2-1.4 feet seas at 6-8 second periods all day. Best window is 3:00 PM to 7:00 PM, with good conditions from morning through evening.

CAUTIONWed Sep 16

Light WSW-W winds build from near-calm to 7-8 knots by afternoon, with small 1.0-1.2 feet seas at comfortable periods. Moderate confidence (58%) means afternoon gusts and direction could shift, so mornings before 10:00 AM are the more reliable window.

Wind and wave heights stay light and manageable across all three days, with Tuesday standing out as the most confident, calm GO day. Monday and Wednesday show genuinely gentle conditions on paper, but low model confidence in wind speed, gusts, and direction means the forecast could shift, so treat them with a bit more caution and keep an eye on updates closer to departure.

Strait of Georgia Boating Forecast

Live GO / CAUTION / NO-GO conditions for Strait of Georgia — the open water between Vancouver and Nanaimo, sheltered from Pacific swell by Vancouver Island. Almost all of its sea is locally generated wind chop, so a summer northwesterly building through the afternoon matters more here than any swell arriving from offshore.

📋 Latest outlook: Light winds and small seas, but low forecast confidence adds caution

CAUTIONMon Sep 14

Monday begins gusty (15-16 kt ESE, gusts to 21 kt) overnight but eases to just 6-8 kt by afternoon, with small 0.5-1.4 feet seas throughout. Model confidence is low, so plan for the calmer 10:00 AM-4:00 PM window and stay flexible.

CAUTIONTue Sep 15

Tuesday starts very calm (2-6 kt) but builds to 11-12 kt WNW winds by afternoon with seas up to 1.2-1.4 feet at short 2-second periods. Wind speed and gusts show notable model disagreement, so favor the calm early morning and watch conditions if going out later.

CAUTIONWed Sep 16

Wednesday builds from a calm 4-5 kt NNW start to 12-15 kt WNW winds with gusts to 20 kt by evening, and seas steepen to 1.6-1.8 feet at a short 2-second period from the NW as wind-wave rides on top of the same-direction swell. Wind speed model disagreement is high, so favor early hours and use caution later in the day.

Wind and wave heights stay modest all three days (generally under 16 knots and under 2 feet), but model confidence is low-to-moderate (42-57%), with wind speed, gusts, and direction diverging significantly across models. This uncertainty is the main reason for the CAUTION rating despite otherwise mild sea states.

Halifax Approaches Boating Forecast

Live GO / CAUTION / NO-GO conditions for Halifax Approaches — the open Atlantic approaches south of Chebucto Head, outside the shelter of Halifax Harbour. Long-period swell runs here independently of local wind, so a calm morning ashore says very little about the sea state past the headland.

📋 Latest outlook: NO-GO Monday-Tuesday, improving to caution by Wednesday

NO-GOMon Sep 14

NO-GO day: dangerous steep chop with gusts to 37 knots and seas near 7 feet at 4-5 second periods, plus heavy rain and low forecast confidence. Avoid boating entirely on Monday.

NO-GOTue Sep 15

NO-GO overnight into morning due to a confused cross-sea (S swell crossing NNW wind-wave) with gusty 15-18 knots N winds. Afternoon turns excellent with light winds and tidy 2-3 feet seas, but the day overall remains NO-GO.

CAUTIONWed Sep 16

CAUTION day - calm and comfortable through early afternoon with light winds and small 2 feet seas at 6-7 second periods. A steep wind-wave chop develops in the evening as WSW winds build to 15 knots, so plan your return before then.

This is a NO-GO stretch overall, with dangerous seas and confused wave patterns dominating Monday and Tuesday. Conditions ease significantly by Wednesday, though lingering wind-wave chop keeps it in caution territory. Mariners should hold off until Wednesday and even then watch for a few rougher hours.

📋 Latest outlook: Tre giorni favorevoli per uscire in mare, mare poco mosso e vento leggero

GOMon Sep 14

Giornata ottima con vento leggero da nord-est sotto i 5 nodi e mare poco mosso tutto il giorno. Leggero rinforzo del vento nel tardo pomeriggio da sud, ma condizioni sempre navigabili.

GOTue Sep 15

Condizioni ancora favorevoli con vento debole variabile tra nord-est e sud, mai oltre i 6 nodi, e mare poco mosso tutto il giorno. Confidenza dei modelli moderata, ma quadro generale stabile.

GOWed Sep 16

Mattinata calma con vento sotto i 4 nodi e mare poco mosso, ma nel pomeriggio il vento da sud rinforza fino a 9 nodi con raffiche di 20-22 nodi e il mare passa a mosso. Meglio rientrare entro mezzogiorno.

Da lunedì a mercoledì le condizioni restano navigabili con vento debole e mare poco mosso, salvo un peggioramento graduale mercoledì pomeriggio quando il vento da sud-est rinforza fino a 9 nodi con raffiche più intense e il mare passa a mosso. La confidenza dei modelli è alta lunedì e martedì, ma scende a livello moderato mercoledì per divergenze su vento e raffiche, quindi conviene monitorare gli aggiornamenti prima di partire nel pomeriggio.

Palermo Boating Forecast

Live GO / CAUTION / NO-GO conditions for Palermo — the Tyrrhenian gulf below Monte Pellegrino — open to the north, so a northerly tramontana or grecale sends swell straight in while a southerly blows offshore and leaves the inshore water deceptively flat.

📋 Latest outlook: Tre giorni di condizioni favorevoli con vento leggero e mare poco mosso

GOMon Sep 14

Lunedì offre mare poco mosso (0,3-0,4m) e vento debole, da quasi nullo la notte a 7-8 nodi da nord-nord-est nel pomeriggio con raffiche fino a 21 nodi. Condizioni favorevoli tutto il giorno, ideali sia al mattino presto che in serata.

GOTue Sep 15

Martedì presenta mare poco mosso (0,3-0,4m) e vento che passa da quasi calmo al mattino a 8 nodi da nord nel pomeriggio, con raffiche fino a 20 nodi. Giornata interamente favorevole, con le condizioni migliori in tarda serata.

GOWed Sep 16

Mercoledì offre le condizioni più calme della settimana: mare poco mosso (0,2-0,4m) e vento debole, massimo 7 nodi da nord-nord-est nel pomeriggio con raffiche sotto i 18 nodi. Giornata favorevole dall'alba al tramonto, ideale per uscire in qualsiasi momento.

Le prossime tre giornate offrono condizioni molto favorevoli per la navigazione da diporto, con venti generalmente leggeri (massimo 7-8 nodi) e mare poco mosso su tutto l'arco temporale. Le raffiche pomeridiane, seppur più marcate nelle ore centrali, rimangono gestibili e non compromettono la sicurezza della navigazione. L'incertezza dei modelli riguarda soprattutto le raffiche di vento, ma la componente di vento medio e le onde risultano coerenti tra i modelli.

MidAtlantic Tournament Marine Weather — Cape May to the Canyons

Live GO / CAUTION / NO-GO conditions across 3 zones for the MidAtlantic Tournament.

📋 Latest outlook: Choppy seas Mon-Tue keep boats in; Wed offers calm relief

NO-GOMon Sep 14

Winds run 6-21 knots NNW with gusts to 29 knots, and while mornings look calmer, waves build to 3.0-5.2 feet at just 5-second periods from the ENE for a steep, choppy chop most of the day. Low confidence and rough afternoon seas make this a NO-GO.

NO-GOTue Sep 15

Winds ease into the good range for most of the day at 10-19 knots NE, but seas stay rough, holding at 3.9-5.3 feet on short 5-second periods from the NE well into the afternoon. Combined with low forecast confidence, conditions add up to a NO-GO.

CAUTIONWed Sep 16

A big improvement: winds stay light all day at 4-9 knots ENE with gusts only to 13 knots, and waves settle to 3.0-3.8 feet at a more organized 6-second period from the east. Only a brief early-morning wave hiccup keeps this from a full green light, so it's CAUTION overall, best late morning onward.

Wednesday 1:00 AM to 11:00 AM is the pick, with light 4-9 knots ENE winds and manageable 3.0-3.8 feet seas at 6-second periods from the east.

📋 Latest outlook: Rough seas early week, calm returns Wednesday

NO-GOMon Sep 14

Winds run 5-19 knots NNW with gusts to 27 knots, and steep wind-wave chop builds through midday into evening as seas hold 2.8-5 feet at just 5-second periods from the NNE. That short period makes for choppy, uncomfortable seas most of the day - not a safe day to be out.

NO-GOTue Sep 15

Winds are steadier at 7-17 knots NE, but waves stay dangerous through the morning and midday, running 3.1-5 feet at 5-second periods from the NE - a choppy, punchy sea state. Conditions only ease late in the day, but low confidence keeps this a NO-GO overall.

GOWed Sep 16

A great day on the water: light 1-6 knots ENE winds with gusts under 11 knots and gentle 2.6-3 feet seas at 6-second periods from the east. Waves stay good all day, with the smoothest, most organized conditions from early morning through midday.

Wednesday 1:00 AM to 12:00 PM is the pick, with light 4 knots ENE winds and gentle 3 feet seas at 6-second periods from the east making for smooth, organized conditions.

📋 Latest outlook: Light winds all week, but caution flagged for building SW swell

CAUTIONMon Sep 14

Light NNW winds under 10 knots and organized 4.1 feet SW swell at 8-9 seconds make for a pleasant-looking Monday, but low model confidence (56%) on wind and gusts means conditions should be reconfirmed before heading out. Best window is midday to afternoon.

CAUTIONTue Sep 15

Tuesday's winds stay light under 6 knots, and the SW swell holds a comfortable 10-second period through most of the day, but it builds to nearly 4.8 feet by evening pushing conditions into caution after 8:00 PM. Model confidence is moderate (61%), so keep plans flexible and finish up before dark.

CAUTIONWed Sep 16

Light winds under 8 knots continue Wednesday, but the SW swell has grown to 4.8-4.9 feet at 10-11 second periods, keeping wave conditions in caution all day. Model confidence is moderate (62%), so approach with care despite the calm-looking wind forecast.

Wind stays light across all three days, but confidence is only moderate (56-62%) and the SW swell steadily builds from 4.1 ft to 4.9 ft, keeping every day at a CAUTION level despite calm breezes. Wave period is generally comfortable, but model spread on gusts and period keeps the safety margin thin.

San Juan International Billfish Tournament Marine Weather — San Juan, Puerto Rico

Live GO / CAUTION / NO-GO conditions on the grounds for the San Juan International Billfish Tournament.

📋 Latest outlook: Light winds but low-confidence forecasts keep it CAUTION all week

CAUTIONMon Sep 14

Winds run 5-14 knots ESE with gusts to 21 knots and seas 1.8-2.3 feet at 6-second periods from the NE - manageable on paper, but a period of steeper wind-driven chop develops for about 4 hours and forecast confidence is only 36%, so stay alert and flexible on timing.

CAUTIONTue Sep 15

A similar setup with 4-13 knots ESE winds, gusts to 20 knots, and 1.8-2.2 feet seas at 5-second periods from the NE keeps things generally comfortable, but confidence is just 48% and a bit of rain is possible, so treat this as a caution day and reassess close to departure.

CAUTIONWed Sep 16

Winds pick up slightly to 5-15 knots E with gusts to 24 knots, and seas run 1.8-2.5 feet at 5-second periods from the ENE - a bit choppier and gustier than earlier in the week. With only 41% confidence, conditions could shift, so plan for caution rather than a clean go.

Sunday night into Monday morning (9:00 PM to 8:00 AM) offers the calmest stretch, with 6 knots ESE winds and 2 feet seas, though forecast confidence is low so double-check conditions before heading out.

📋 Latest outlook: Calm Mon-Tue, but Wed brings dangerous steep chop

CAUTIONMon Sep 14

Light 2-7 knots NW winds and calm 0.7-1.0 feet seas at 3-4 second periods all day Monday. A favorable window for boating, though forecast confidence is only moderate.

CAUTIONTue Sep 15

Light-to-moderate 4-14 knots winds shifting from north to east through Tuesday, with seas staying under 2 feet most of the day. Evening winds and gusts increase, so plan for a cautious, well-timed outing given low forecast confidence.

NO-GOWed Sep 16

Dangerous conditions Wednesday: east winds gusting 24-28 knots build steep 4-6 feet seas at just 4-5 second periods. Rough, punishing chop persists most of the day - stay off the water.

Monday and Tuesday offer light winds and small, well-organized seas, though model confidence is low on both days due to disagreement on wind speed and gusts. Wednesday turns hazardous as easterly winds build past 20 knots with gusts into the high 20s, whipping up steep, short-period seas near 5-6 feet that make for an unsafe, choppy ride - avoid boating that day.
