What is a boating forecast?

A boating forecast is a marine weather forecast built around the conditions that actually decide your day on the water: wind speed and direction, wave height and period, and the overall sea state. Unlike a land forecast, it's not about whether it'll rain — it's about whether the water is safe and comfortable for your boat.

The hard part is reading it. Raw marine data — knots, significant wave height, swell period in seconds — takes experience to interpret. SeaLegs AI does that interpretation for you, turning the numbers into a single, honest rating for each spot and each day:

GO

Favorable conditions for most recreational boats. Light-to-moderate wind, gentle seas, comfortable timing.

CAUTION

Marginal. Manageable for experienced boaters in capable vessels — but check the wind and wave timing first.

NO-GO

Hazardous for small craft. Steep or short-period seas, strong wind. Best to postpone the trip.

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: Great Wednesday; building swell-wind wave conflict later week

GOWed Aug 26

Best day of the period: light 4-12 knots west/northwest winds and calm 2.7 feet seas at 6-7 second periods from the southeast. Ideal window is 11:00 AM to 2:00 PM. Excellent visibility and high confidence.

CAUTIONThu Aug 27

Manageable early, but winds build to 15-17 knots south with gusts over 20 knots by evening and seas climb toward 4.7 feet. Late evening (9:00 PM-11:00 PM) brings a confused cross-sea as ESE swell crosses SSW wind-waves - use caution and plan an earlier return.

NO-GOFri Aug 28

NO-GO through midday: confused cross-sea as ESE swell meets SSW wind-waves, with steep 4-5 feet seas at 5-6 second periods and gusts to 21 knots. Conditions improve after 3:00 PM as winds ease and the cross-sea relaxes - avoid the water until then.

Wednesday offers clean, light-wind conditions ideal for boating, but confidence deteriorates through Thursday night into Friday as a crossing sea state develops between southeast swell and south/southwest wind-waves. Friday's confused cross-sea combined with steep short-period chop makes for an unsafe, uncomfortable ride through midday, improving only in the afternoon.

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: Three straight GO days with light winds and small, calm seas

GOWed Aug 26

Favorable Wednesday with 9-14 kt east-southeast winds (gusts to 19 kt) and small 1.8-2.8 ft seas at 3-second periods. Conditions ease into the evening and overnight, making for a comfortable day on the water throughout.

GOThu Aug 27

Great Thursday with light 9-12 kt southeast winds easing to just 3-5 kt by afternoon. Seas stay small at 1.6-2.3 ft throughout, with the calmest window arriving 4:00 PM to 7:00 PM.

GOFri Aug 28

Excellent Friday with light 4-9 kt east-southeast winds and the smallest seas of the week at 1.2-1.6 ft. Best window is 1:00 PM to 5:00 PM with near-calm conditions - a great day to be on the water.

Wednesday through Friday all offer favorable boating conditions with light winds under 15 knots and small wind-driven seas under 3 feet. Wave periods remain short at 3 seconds throughout, giving a bit of a wind-chop texture, but heights stay modest enough to keep things comfortable for recreational vessels. Confidence is high (95%) across all three days with stable model agreement on wind and wave parameters.

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: Confused cross-seas make all three days unsafe or risky

NO-GOWed Aug 26

NO-GO all day Wednesday - light 8-13 knots winds but a persistent cross-sea with south swell crossing northwest wind-waves creates confused, uncomfortable conditions. Waves build to 7.0 feet with no safe heading available. Avoid boating entirely.

NO-GOThu Aug 27

NO-GO Thursday - improved from Wednesday but still a confused cross-sea (south swell crossing west-northwest wind-waves) for about 10 hours. Winds are light at 9-11 knots, waves ease to 5.5-6.5 feet, but awkward wave interaction keeps this unsafe for boating.

CAUTIONFri Aug 28

CAUTION Friday - a lingering cross-sea (south-southwest swell crossing northwest wind-waves) persists for about 14 hours, though winds stay light at 8-13 knots and waves hold near 5.5-6.0 feet. Conditions are borderline; use caution and prefer early morning hours.

Light 8-16 knot winds mask a persistent confused sea state through the period, with south/southwest swell crossing northwest to west-northwest wind-waves creating awkward, uncomfortable boat motion. Wednesday is the worst day with a full 24-hour cross-sea and building 6-7 ft seas, while Thursday and Friday see the pattern ease slightly but never fully resolve. No day in this outlook offers a genuinely safe, comfortable window 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: Three calm, boat-friendly days with light winds and small seas

GOWed Aug 26

Light 4-9 knot SW-to-S winds and small 0.7-1.1 feet seas make for an easy, comfortable day on the water. Best conditions are in the early morning hours before winds build slightly in the afternoon. A great day to head out.

GOThu Aug 27

Thursday brings the lightest winds of the week, mostly under 8 knots from shifting W/WNW/NNE directions, with tiny 0.5-0.8 feet seas. High forecast confidence supports a smooth, relaxed day on the water with no real trouble spots.

GOFri Aug 28

Friday sees very light 1-5 knot WNW-to-NW winds and consistently small 0.7 feet seas, with a near-calm lull in the evening. A gentle, low-risk day well-suited for boating, especially through midday.

A stable, gentle weather pattern holds through Wednesday to Friday with light winds under 10 knots and tiny wave heights under a foot. Conditions are favorable for recreational boating all three days, with essentially no hour-to-hour risk periods to flag.

San Jaime Bank Boating Forecast

Live GO / CAUTION / NO-GO conditions for San Jaime Bank — a deep bluewater bank about 20 miles 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 choppy swell keeps caution flags up

CAUTIONWed Aug 26

Light north-northwest winds under 11 kt all day, but a persistent 5.0-5.5 ft SSW swell at 9-second periods keeps seas choppy and uncomfortable. Caution advised throughout Wednesday with no clear improvement window.

CAUTIONThu Aug 27

Overnight chop clears by 3:00 AM, giving way to a better afternoon with light 7-11 kt northwest winds and 4.1-4.7 ft southwest swell at 8-9 second periods. Wave period forecasts are uncertain, so exercise caution despite the improved outlook.

CAUTIONFri Aug 28

Friday looks like the best day with light winds and longer-period 10-11 second swell making for smoother seas through the afternoon. But wave period forecasts are highly uncertain, and evening brings building swell and shifting south-southwest winds - aim to return by 6:00 PM.

Winds stay light and manageable across all three days, generally under 11 knots from the northwest. The issue is wave steepness - southerly swell in the 4.5-5.7 ft range is creating uncomfortable, choppy seas that keep every day in caution territory despite the calm wind.

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: Good Wednesday, but wind-wave/swell cross-seas build Thu-Fri

GOWed Aug 26

Excellent conditions all day with light 5-12 kt winds and calm 2.5-foot seas at 6-8 second periods. Best window is 12:00 PM-2:00 PM when winds drop to just 5-6 knots. Great day for boating.

CAUTIONThu Aug 27

Good morning and afternoon with light-to-moderate south winds and 2.5-3.4 foot seas. After 5:00 PM a confused cross-sea forms (ESE swell crossing S wind-wave) plus a steep wind-wave chop with gusts to 22 knots - exercise caution or head in early.

CAUTIONFri Aug 28

Morning through early afternoon has a confused cross-sea (ESE swell crossing S wind-wave) with choppy 4.3-4.6 foot seas despite modest winds. Conditions ease markedly after 3:00 PM as winds go light and seas settle - wait until afternoon to head out.

Wednesday is the standout day with light southwest-to-northwest winds under 12 knots and gentle 2.5-foot seas at 6-7 second periods. Thursday and Friday both see a confused cross-sea develop as SE/ESE swell crosses S/SSW wind-wave, creating an awkward, uncomfortable motion even though wind speeds stay moderate under 15 knots.

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: Light winds, calm seas most days; Thursday has brief afternoon chop

GOWed Aug 26

Light 2-11 kt winds and calm 0.8-1.4 ft seas at 5-8 second periods make for excellent boating all day Wednesday. Conditions stay favorable from morning through evening with no concerning stretches.

CAUTIONThu Aug 27

Good morning conditions with 7-11 kt south winds and 1.4 ft seas, but afternoon (1:00 PM-5:00 PM) brings steeper 1.6-1.8 ft wind-driven chop with gusts to 20 kt. Plan your outing for the morning and be off the water or cautious during the afternoon rough patch.

GOFri Aug 28

Excellent, calm conditions all day with light 3-9 kt winds and gentle 1.5-1.8 ft seas at 6-second periods. One of the best days of the week for boating with no rough stretches to avoid.

Wednesday and Friday offer excellent light-wind, calm-sea boating conditions with waves staying well-organized at 6-second periods. Thursday is mostly good too, but a several-hour stretch of steepening south wind-driven chop combined with building southeast swell creates a rougher, less comfortable ride during the afternoon.

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: Good boating Wed & Fri; Thursday brings a bumpy midday chop

GOWed Aug 26

Light 7-9 knots south/southwest winds and calm 1-2 feet seas at 2-second periods all day Wednesday. Consistent conditions from morning through evening - a great day to be on the water anytime.

CAUTIONThu Aug 27

Steep wind-wave chop builds mid-morning as west-southwest winds hit 10-11 knots with gusts to 18 knots and seas reach 3.1 feet at a short 3-second period - the wind-wave rides on top of the swell from the same westerly sector, steepening the seas. Best to avoid roughly 5:00 AM-10:00 AM and the 4:00 PM-7:00 PM gusty spell; midday and evening are more comfortable.

GOFri Aug 28

Friday is the calmest day with light 2-7 knots north-northeast winds and tiny 1-1.5 feet seas at 2-second periods all day. Great conditions for any departure time, especially the quiet morning hours.

This stretch offers mostly light winds and small seas, with Wednesday and Friday standing out as excellent boating days. Thursday sees building west-southwest winds and a short-period wind-wave that creates a steeper, choppier sea mid-morning through midday, tempering an otherwise decent day.

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: Midweek chop makes way for a calm, boat-friendly Friday

NO-GOWed Aug 26

NO-GO Wednesday: steep 3.5-4.1 feet SW seas at just 3-4 second periods peak midday with 14-15 knot SW winds gusting to 24 knots. Even the calmer morning and evening hours carry lingering chop. Best to stay off the water entirely.

CAUTIONThu Aug 27

CAUTION Thursday: generally light 6-11 knot NNW winds with 2-3 feet seas, but 11:00 AM-2:00 PM brings a steeper 2.6-2.8 feet chop at short 3-second periods with gusts to 19 knots. Morning and evening hours are the better bets.

GOFri Aug 28

GO Friday: light 1-9 knot NE/N winds and calm 0.5-1.9 feet seas all day make this the best day of the week. Comfortable, easy conditions from morning through evening with no real weak spots.

Wednesday brings a steep, short-period wind-driven chop from the southwest that turns midday hours unsafe, while Thursday improves to mostly manageable conditions with just a brief early-afternoon rough patch. Friday is the standout day with light winds and calm, well-organized seas nearly all day, making it the clear pick for boating this week.

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: Good conditions with Thursday's afternoon chop needing caution

GOWed Aug 26

Great conditions all day with light 3-10 knots winds and small, well-organized 1.5-2.2 feet seas at 6-7 second periods from the southeast. No caution windows - a solid choice for boating.

CAUTIONThu Aug 27

Morning is calm with light south winds and small seas, but midday into afternoon brings building south winds to 19 knots gusts and a steeper, choppier wind-wave chop for about 4 hours. Conditions ease again by evening - time your trip around the afternoon caution window.

GOFri Aug 28

Light winds under 6 knots and organized 2.3-3.1 feet seas at 5-6 second periods from the southeast make for a comfortable, low-stress day on the water. High confidence forecast with no caution periods.

Wednesday and Friday offer favorable light-wind, small-wave conditions ideal for boating, while Thursday sees building south winds and a steeper afternoon wind-wave chop that requires more careful timing. Overall confidence is good across the period (87-95%), though wave period modeling shows some divergence on Wednesday.

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: Good Wednesday, deteriorating Thu-Fri with rising wind and swell

GOWed Aug 26

Excellent conditions all day Wednesday with light 5-12 knots west/northwest winds and calm seas under 1.5 ft at 2-second periods. High confidence forecast makes this the best day of the period for boating.

NO-GOThu Aug 27

Thursday morning is manageable with light north winds and small seas, but conditions turn rough by afternoon. From 3:00 PM onward, wind builds to 15 knots with 25 knots gusts and steep 3.5 ft seas at 3-second periods - avoid boating from mid-afternoon through the evening.

NO-GOFri Aug 28

Friday opens rough with steep 3-4 ft seas and gusty 20+knots north winds overnight into early morning - unsafe for boating. Conditions ease somewhat by mid-morning with longer wave periods, but lower model confidence means caution is still warranted, especially before 7:00 AM.

Wednesday offers calm, light-wind conditions ideal for boating, but a building northerly flow brings steadily rising seas and wind through Thursday afternoon into Friday. Thursday evening and Friday's early morning hours see steep, short-period wind-chop that becomes unsafe, with some improvement by Friday mid-morning as seas ease.

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, small seas — Thursday afternoon chop needs caution

GOWed Aug 26

Light 3-6 knots west winds and calm seas under 1.4 feet make Wednesday the best day of the period. Conditions stay favorable and even improve into the evening. Great for boating any time of day.

CAUTIONThu Aug 27

Thursday morning is calm with light north winds and small seas under 1.2 feet - a great window. By afternoon a north-northwest wind-wave stacks on the existing north swell, steepening the chop to near 2 feet with gusts to 25 knots for a few hours, so caution is warranted then. Best to be out earlier in the day.

GOFri Aug 28

Friday starts with the roughest conditions of the period - winds to 13 knots and seas near 2.8 feet overnight - but steadily improves through the day. By afternoon winds ease to 7-9 knots and seas settle toward 2 feet at better-organized 5-second periods. A good day overall, best enjoyed from mid-morning on.

Overall a favorable three-day stretch with light winds and small, well-organized seas dominating Wednesday and Friday. Thursday starts calm but develops a steepening wind-wave chop on top of the existing swell during the afternoon and evening, warranting caution during that window. Confidence is high to moderate across all three days, with some uncertainty in wave period/direction models for Thursday.

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: Good boating Wed-Fri, but Thursday brings choppy cross-seas

GOWed Aug 26

Light 2-12 kt winds and small 1-2 ft seas at 5-6 second periods make Wednesday a great, comfortable day for boating. Conditions stay favorable from morning through evening with no significant concerns.

CAUTIONThu Aug 27

Thursday sees building SSE winds (10-13 kt, gusts to 29 kt) and steep 2-2.3 ft seas at just 3-4 seconds from late night into midday, making for choppy, uncomfortable conditions during that stretch. Winds and seas relax again by evening, so time your outing around the calmer morning or evening hours.

GOFri Aug 28

Friday is the pick of the week with light 5-9 kt winds and small, well-spaced 1.2-1.7 ft seas at 4-6 second periods. Expect smooth, comfortable conditions throughout the day with high confidence in the forecast.

Wednesday and Friday offer light winds and gentle, well-organized seas ideal for boating. Thursday remains a GO overall but a steep, short-period wind-wave chop develops for about 10 hours as southerly winds pick up, creating an uncomfortable, confused sea state that warrants extra caution.

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: Rough seas and cross-swell make this a NO-GO stretch through Thursday

NO-GOWed Aug 26

NO-GO Wednesday: a confused cross-sea forms as building SSE swell crosses leftover NE wind-wave, producing awkward, uncomfortable seas up to 6.7 feet at 6-7s periods. Winds are light (6-12 knots S/SSW) but that doesn't offset the rough, disorganized wave state. Avoid boating all day.

NO-GOThu Aug 27

NO-GO Thursday: large SSE swell keeps seas at 4.9-6.7 feet at 8-9s periods all day despite very light winds. High confidence forecast - conditions are simply too big for recreational boating, plan to stay ashore.

CAUTIONFri Aug 28

CAUTION Friday: swell eases to 4.2-5.0 feet at 7-9s from the SSE but a choppier patch hits mid-morning (8-11 AM). Winds are light (2-8 knots) all day. Best window is midday to evening once seas settle - use caution and check conditions before departing.

This is a NO-GO period overall, driven by building southerly swell that clashes with residual easterly wind-wave energy early Wednesday, then large SSE swell dominating Thursday. Friday improves as the swell drops and organizes, but a confused morning chop keeps it at CAUTION rather than a clear GO.

Cook Strait Boating Forecast

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: Three-day stretch of gale-force winds and steep, confused seas — stay in port

NO-GOWed Aug 26

Steep 6-8 ft WNW wind-wave chop paired with 24-30 kt NNW-NW winds (gusts to 40 kt) dominate Wednesday, easing only slightly by afternoon as a new S swell builds in underneath. Sea state remains unsafe most of the day — not a boating day.

NO-GOThu Aug 27

A confused cross-sea sets up Thursday as 8-9 ft S swell crosses building N wind-waves, creating awkward, uncomfortable motion. Winds also ramp from a light 13 kt morning to 28-30 kt gusting 40+ knots by evening — unsafe conditions all day.

NO-GOFri Aug 28

Gale-force NNW winds to 37 kt (gusts 51 kt) combine with steep 9-10 ft wind-wave chop and a confused S-swell-versus-NW-wind-wave cross-sea. High model confidence confirms this as the most dangerous day of the period — stay off the water.

This entire period is a NO-GO from Wednesday through Friday, driven by strong-to-gale-force northwest and north winds combined with steep wind-driven chop and, on Thursday and Friday, a confused cross-sea where southerly swell meets northerly wind-waves. Even the brief lulls don't offer safe, comfortable conditions given the underlying sea state. Recreational vessels should stay off the water until this pattern clears.

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: Rough seas and crossing swells make this a no-go week

NO-GOWed Aug 26

NO-GO day with winds building to 22-26 knots SSE (gusts 33 knots) and 8.5-8.7 feet seas at 14-second periods. A WSW swell crosses SSW-SSE wind-waves creating a confused, choppy cross-sea for hours, plus nearly an inch of rain. Stay off the water.

NO-GOThu Aug 27

NO-GO all day: 17-22 knots S-SE winds (gusts to 30 knots) with 6-8.7 feet seas at 11-13 second periods. WSW swell crosses S wind-waves the entire day, creating a confused, uncomfortable cross-sea with steep chop throughout. Not a safe day to boat.

CAUTIONFri Aug 28

CAUTION day: winds ease to 13-19 knots SE in the best windows (early morning and after 3:00 PM), with waves dropping to 3.5-4 feet at 10-12 second periods. A lingering WSW swell crosses SSE wind-waves all day, keeping a confused cross-sea present. Avoid the midday 10:00 AM-2:00 PM stretch when winds gust near 28 knots.

A strong wind-wave/swell mismatch dominates Wednesday through Friday, with confused cross-seas and steep wind-wave chop driving unsafe conditions for most of the period. Winds build into the 20-26 knot range with gusts over 30 knots on Wednesday and Thursday, while a persistent WSW swell at 12-14 second periods crosses newer wind-generated seas from the south and southeast, producing an awkward, uncomfortable ride with no comfortable heading. Friday improves somewhat with a wider good-wind window, but the lingering cross-sea keeps it at caution rather than a clear go.

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 GO days with light winds and gentle seas

GOWed Aug 26

Light winds and calm, long-period seas dominate the morning and midday, with a breezier but still manageable afternoon (15-17 knots W, gusts near 30 knots) before calming again by evening. Best window is late morning into early afternoon.

GOThu Aug 27

Light 4-10 knot ENE/NE winds all day with seas building to around 3.4 feet at 5-6 second periods from the E by afternoon. Comfortable conditions throughout, with the lightest winds in the morning.

GOFri Aug 28

Light winds and moderate 2.3-3.1 foot seas at 6-8 second periods from the E/ESE, with a brief morning wind bump (12-13 knots, gusts to 24 knots) around 8:00-9:00 AM. Calms further by afternoon and evening for a pleasant finish.

This is a great stretch for boating with all three days rated GO. Winds stay light to moderate throughout (mostly under 17 knots) and seas remain small at 2-3.4 feet with generally organized period, making for comfortable outings each day.

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: Confused seas building midweek; overall NO-GO conditions

CAUTIONWed Aug 26

Light winds all day, but a S swell starts crossing an ESE/ENE wind-wave by late morning, creating a confused, uncomfortable sea by afternoon. Best window is before 10:00 AM NZST while seas remain under 3 feet. Caution advised for the rest of the day.

NO-GOThu Aug 27

Dangerous, confused sea state most of the day as S/SSE swell crosses ENE/NE wind-wave, with seas peaking near 6.3 feet overnight and 6.2 feet in the evening. Winds are light, but wave interaction makes conditions unsafe. This is a NO-GO day — stay off the water.

CAUTIONFri Aug 28

Overnight confused seas ease by early morning, giving way to organized SE/SSE swell around 4-9-10-second periods and light W/WNW winds under 6 knots. Best window is 9:00 AM to 2:00 PM as seas drop to 3.5-4 feet. Use caution before sunrise while the cross-sea lingers.

This forecast period is dominated by a persistent long-period S/SE swell crossing with a separate wind-wave from the E/ENE quadrant, producing a confused sea state that peaks Thursday with dangerous 6+ foot combined seas. Winds stay light to moderate throughout (under 15 knots), so wave interaction rather than wind is the main hazard. Only Friday afternoon offers a genuinely settled window as the swell and wind-wave trains align.

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 calm seas

GOWed Aug 26

Light sub-6 kt south winds and small 2-2.5 ft east swell at 5-6s periods make for an easy, comfortable day on the water. Best conditions are mid-morning through afternoon.

GOThu Aug 27

Light 3-9 kt south to southwest winds and organized 3 ft east swell at 5-6s periods keep Thursday comfortable. Early morning gusts to 24 kts ease by mid-morning, leaving a smooth midday-to-evening window.

GOFri Aug 28

Slightly larger 3.5-3.9 ft east swell at a steady 6s period keeps Friday comfortable, with light 3-10 kt south to southeast winds. Overnight gusts to 25 kts ease by early morning, leaving a smooth day from mid-morning onward.

A stable, high-pressure pattern keeps winds light and seas small across Wednesday through Friday, making all three days solid GO conditions for recreational boating. Wave heights build slightly through the period (2.5 ft to 3.7 ft) but remain well-organized easterly swell at 5-6 second periods, so the ride stays comfortable throughout.

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: One good day, then rough seas and rain shut things down

GOWed Aug 26

Light winds under 10 knots and seas under 3 feet at short periods make for a comfortable day. Best window is 6:00 PM-10:00 PM with calm 2-4 knot winds and seas under 2 feet. High confidence forecast.

NO-GOThu Aug 27

Calm morning gives way to rapidly building north swell, with seas growing from 2 feet to 6 feet at short 3-5 second periods and gusts up to 28 knots by evening. Only the pre-11:00 AM window is safe; afternoon and evening are hazardous.

NO-GOFri Aug 28

Dangerous leftover swell peaks near 7.2 feet overnight before gradually easing, while rain (0.51in) moves through during the day reducing visibility. Despite lighter winds, residual rough seas and rain keep this a no-go day.

Wednesday offers light winds and calm seas, but Thursday afternoon brings building north swell and Friday adds heavy rain on top of steep seas. Overall this three-day window is a NO-GO due to deteriorating wave conditions and precipitation.

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: Three straight GO days with light winds and calm seas

GOWed Aug 26

Good conditions all day with winds easing from 11-12 knots SSW in the morning to just 6-7 knots W by afternoon. Seas stay small at 0.8-1.6 feet with short 3-second periods. Best window is after 1:00 PM as everything calms further.

GOThu Aug 27

Very light winds (1-8 knots) and tiny seas (0.3-0.8 feet) make this an excellent day for boating from morning through evening. Some model uncertainty on wave period details, but conditions should stay calm and comfortable throughout.

GOFri Aug 28

Light winds (4-9 knots) and small seas (0.5-1.1 feet) all day, with the best-organized waves around midday at 5-6 second periods. Winds build slightly toward evening but stay easily manageable. A calm, comfortable day overall.

This is a favorable three-day stretch for boating with consistently light winds and small, short-period wind chop throughout. Wednesday sees the most breeze in the morning before easing, while Thursday and Friday are notably calm with winds under 10 knots nearly all day.

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: Wednesday is a great boating day; Thu-Fri turn unsafe

GOWed Aug 26

Light 2-10 knot winds and calm 1-1.5 feet seas at 6-8 second periods make Wednesday the best day to be out. Conditions stay comfortable and well-organized around the clock.

NO-GOThu Aug 27

Thursday looks manageable early with light winds and small seas, but conditions worsen sharply after 6:00 PM as winds and short-period seas build. Overall a NO-GO day given the deteriorating evening trend, with the roughest conditions arriving by 11:00 PM.

NO-GOFri Aug 28

Friday is dangerous with steep 5 feet seas at 4-6 second periods and gusts up to 31 knots persisting most of the day. Conditions only start easing after 8:00 PM - avoid this day entirely.

Only Wednesday offers safe, comfortable conditions with light winds and small, well-organized seas. Thursday deteriorates late as northeast winds build, and Friday brings dangerous steep 5-foot short-period seas with strong gusts, making the overall outlook a NO-GO for the back half of the period.

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: Confused cross-seas dominate; Thursday's rough chop is a NO-GO

CAUTIONWed Aug 26

Light winds and organized 3-4 feet seas at 6-7 second periods make Wednesday the best day, especially 7:00 AM-10:00 AM. Late evening brings a developing cross-sea as ENE swell crosses SSE wind-wave, so plan to return before 11:00 PM.

NO-GOThu Aug 27

Thursday is a NO-GO: an E swell crosses an SE wind-wave for about 8 hours (1:00 AM-2:00 PM AEST), creating a confused, uncomfortable sea with seas up to 5.3 feet at short 6-second periods. Even the afternoon improvement only reaches caution level - stay off the water.

CAUTIONFri Aug 28

Friday remains caution-level with a lingering confused sea state, seas around 4.8-5.3 feet at 8-second periods from the southeast. Winds are light, but wave forecasts have low confidence (68%) and are diverging, so expect possible surprises in sea conditions.

Winds stay light all three days, but a persistent cross-sea between swell and wind-wave trains creates awkward, uncomfortable motion, peaking Thursday when seas build to 5.3 feet at 6-second periods from the southeast. Friday remains caution-level as the confused pattern lingers even though wave heights ease slightly overnight. Only Wednesday offers a solid window before the cross-sea develops late in the day.

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: Three straight GO days with light winds and calm seas

GOWed Aug 26

Wednesday is the calmest day of the week, with winds under 10 knots from the south/southeast and seas around 0.7-1.1 feet all day. Excellent conditions throughout with no notable weak points.

GOThu Aug 27

Thursday sees winds build to 12-13 knots (gusts to 20 knots) from the southeast around midday, with seas peaking near 1.6 feet at short 2-second periods - a bit bumpy but still a GO. Early morning and evening are calmer with lighter winds and smaller seas.

GOFri Aug 28

Friday begins breezy with 9-10 knots winds and gusts to 18 knots from the southeast, easing steadily through the day to just 5-6 knots by afternoon. Seas calm to 0.6-0.7 feet later in the day, making midday onward the best window.

This is an excellent three-day stretch for boating with light-to-moderate winds and small, well-organized seas throughout. Wednesday is the calmest day, while Thursday sees a modest increase in southeast winds and short-period wind chop before easing again Friday. Confidence is high (95%) across all three days, so these forecasts should hold up well.

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: Three good boating days with light winds and calm seas

GOWed Aug 26

Light 5-7 knots west winds and calm 0.9-1.2 feet seas at 4-5 second periods make Wednesday an excellent, easy day on the water. Conditions stay steady and comfortable from morning through night with no concerning chop.

GOThu Aug 27

Thursday morning is glassy calm with 4-7 knots winds and tiny seas at long 6-8 second periods - ideal boating conditions. Wind and short-period chop build through the afternoon and evening, so plan to be out early for the smoothest ride.

GOFri Aug 28

Friday sees the choppiest conditions of the stretch, with 10-12 knots north winds and seas building to about 3.0 feet at short 4-second periods by midday. Still a good day overall, but an early morning or evening departure avoids the peak midday chop.

This is a strong three-day stretch for boating with light-to-moderate winds and small, manageable seas throughout. Wednesday and Thursday are especially calm, while Friday sees a gradual build in wind and wave height but stays within comfortable limits all day. Confidence is high early in the window and drops somewhat by Friday, mainly around wave height and period, but conditions remain boat-friendly.

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: Three straight GO days with light wind and calm, tiny seas

GOWed Aug 26

Good boating day with light morning winds building to a moderate midday peak near 15-16 knots ESE, then easing in the evening. Seas stay small (under 1.6 feet, short period) all day. Best window: 4:00 PM-8:00 PM when winds ease and conditions turn glassy.

GOThu Aug 27

Calm morning (4-8 knots E, seas under 0.5 feet) gives way to a breezier afternoon peaking near 14-15 knots ESE with gusts to 21 knots and seas up to 1.6 feet. Still a GO day overall - just favor the early hours for the smoothest conditions.

GOFri Aug 28

Light easterly winds (7-11 knots) and small seas (under 1.1 feet) make for an easy, comfortable GO day. Lightest winds are in the early morning and evening, with only a minor midday bump. Great visibility and stable forecast throughout.

A stable, high-confidence pattern holds across Wednesday through Friday with light-to-moderate east-to-southeast winds and small, short-period wind chop under 2 feet. No fronts or hazards are in the picture, making this a solid three-day stretch for recreational boating, though afternoon breezes build enough on each day to warrant slightly earlier or later outings for the smoothest ride.

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: Light winds all week but crossing swells create bumpy chop

CAUTIONWed Aug 26

Light 9-13 kt SW winds and 3.5-4.6 ft seas look tame, but a confused cross-sea (SSE swell vs SW wind-wave) makes for uncomfortable, choppy motion for much of the day. Best window is 10:00 AM-2:00 PM ADT when things settle down. Avoid early morning hours when the chop is worst.

CAUTIONThu Aug 27

Thursday is the pick of the week - near-calm winds (2-6 kt) and organized 7-second SSE swells dominate through midday. A brief confused cross-sea develops later as SW wind-waves cross the swell, so plan your outing for the 4:00 AM-1:00 PM ADT window for the smoothest ride.

CAUTIONFri Aug 28

Friday's wind (11-13 kt S/SSW, gusts to 17 kt) and wave heights (3-3.7 ft) look mild, but shortening 5-second periods and a confused cross-sea between the SSE swell and S wind-wave create choppy, uncomfortable seas for several hours. Best to go early, 6:00 AM-9:00 AM ADT, before conditions turn awkward later in the day.

Wind and wave heights stay modest all three days (mostly under 15 knots and under 5 feet), but a persistent SSE swell crossing SW-to-S wind-waves produces confused, choppy seas during parts of each day. Thursday offers the calmest, most organized window as winds go nearly calm overnight into midday. Use caution timing departures around the cross-sea periods even though wind and wave heights alone look benign.

Marseille Boating Forecast

Live GO / CAUTION / NO-GO conditions for Marseille — France's great Mediterranean port city — the rade de Marseille and the calanques coast, where a rising mistral can turn a calm morning into a short, steep sea by afternoon.

📋 Latest outlook: Vent d'est renforcé jeudi crée un clapot court et dangereux

CAUTIONWed Aug 26

Matinée calme avec vent léger et mer bien rangée, mais un clapot court et raide s'installe de la mi-journée au début de soirée avec des rafales jusqu'à 27 nœuds. Le vent d'est-sud-est mollit ensuite en soirée. Prévoir de naviguer tôt ou tard dans la journée.

NO-GOThu Aug 27

Vent d'est-sud-est à sud-est soutenu (13-16 nœuds, rafales jusqu'à 33 nœuds) et creux de 1,2-1,3 m à période courte de 4 s créent une mer dure et dangereuse presque toute la journée. Conditions inadaptées à la plaisance. Mieux vaut reporter la sortie.

CAUTIONFri Aug 28

Mer encore marquée en début de journée (creux 0,9-1,0 m, rafales jusqu'à 28 nœuds), nécessitant de la prudence jusque vers 9 h. Nette amélioration l'après-midi avec vent modéré et creux sous 0,8 m, puis conditions calmes en soirée. Privilégier un départ après 13 h.

La semaine s'ouvre dans de bonnes conditions mercredi matin, avant qu'un vent de sud-est à est se renforce nettement, générant un clapot court et raide qui dégrade la mer jusqu'à vendredi. Jeudi concentre les creux les plus marqués et les rafales les plus fortes, ce qui impose de rester à quai une bonne partie de la journée. Vendredi voit une lente amélioration, avec une mer encore inconfortable en début de nuit puis plus maniable l'après-midi.

CAUTIONWed Aug 26

Vents légers de secteur nord-est à sud-est (jusqu'à 12 nœuds) et creux de 0,5 à 0,7 m bien rangés toute la journée. Une courte période de trois heures en fin de matinée voit un clapot se superposer à la houle, restant maniable. Excellente journée globale pour naviguer.

NO-GOThu Aug 27

Dégradation nette entre 8 h et 15 h : vent d'est à 10 nœuds avec rafales à 26 nœuds et creux de 1,0 m à 3 s de période, clapot court et raide inconfortable et risqué. Avant 8 h et après 16 h, conditions plus calmes. Éviter toute sortie durant la fenêtre centrale de la journée.

CAUTIONFri Aug 28

Entre 8 h et 14 h, une houle de sud croise un clapot de vent tournant du sud-sud-est au sud-ouest, créant une mer croisée inconfortable sans bon cap. Avant 8 h et après 15 h, creux sous 0,6 m et vents modérés offrent de meilleures conditions. Privilégier ces créneaux pour sortir.

La semaine s'ouvre sur des conditions favorables mercredi avec vents et creux modestes, puis se dégrade nettement jeudi avec un clapot court et raide qui rend la sortie déconseillée en milieu de journée. Vendredi reste praticable mais une mer croisée en fin de matinée impose une vigilance particulière sur le choix du cap.

GOFri Aug 28

Vent très léger le matin, renforcé à 8-11 nœuds de secteur ouest en soirée. Creux faibles de 0,3 à 0,4 m toute la journée, mer maniable malgré une confiance modérée sur les modèles de creux.

Les trois journées présentent des conditions globalement favorables à la plaisance, avec des vents légers à modérés et des creux modestes bien rangés. Le week-end voit une légère hausse du vent jeudi après-midi et une divergence des modèles sur les creux vendredi, mais rien qui remette en cause la sortie.

📋 Latest outlook: Journée calme jeudi, prudence mercredi et vendredi (pluie, clapot)

CAUTIONWed Aug 26

Vents d'est modérés (jusqu'à 10 nœuds, rafales à 20 nœuds) et petits creux de 0,3-0,4 mètre, mais des averses (0,51 pouce) traversent la journée en milieu de journée. Mieux vaut sortir tôt le matin ou en fin de journée pour éviter la pluie.

Journée quasi parfaite avec des vents sous 5 nœuds de secteur sud-ouest et une mer bien rangée à 0,3-0,5 mètre, période 4 à 6 secondes. Aucune période à éviter — sortie recommandée à tout moment.

CAUTIONFri Aug 28

Un clapot court et raide se superpose à la houle d'ouest-sud-ouest tôt le matin (6 h – 8 h), avant des vents renforcés à 12 nœuds (rafales à 24 nœuds) et des averses (0,60 pouce) en matinée. Mieux vaut attendre l'après-midi, une fois la mer et le vent apaisés.

La semaine offre globalement des conditions favorables à la plaisance, avec un jeudi quasi idéal en vents et creux légers. Mercredi et vendredi passent en vigilance en raison d'averses notables et, pour vendredi, d'un clapot court et raide en début de matinée qui rend la mer inconfortable pendant quelques heures.

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.

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

📋 Latest outlook: Good Wednesday, but wind-wave/swell cross-seas build Thu-Fri

GOWed Aug 26

Excellent conditions all day with light 5-12 kt winds and calm 2.5-foot seas at 6-8 second periods. Best window is 12:00 PM-2:00 PM when winds drop to just 5-6 knots. Great day for boating.

CAUTIONThu Aug 27

Good morning and afternoon with light-to-moderate south winds and 2.5-3.4 foot seas. After 5:00 PM a confused cross-sea forms (ESE swell crossing S wind-wave) plus a steep wind-wave chop with gusts to 22 knots - exercise caution or head in early.

CAUTIONFri Aug 28

Morning through early afternoon has a confused cross-sea (ESE swell crossing S wind-wave) with choppy 4.3-4.6 foot seas despite modest winds. Conditions ease markedly after 3:00 PM as winds go light and seas settle - wait until afternoon to head out.

Wednesday is the standout day with light southwest-to-northwest winds under 12 knots and gentle 2.5-foot seas at 6-7 second periods. Thursday and Friday both see a confused cross-sea develop as SE/ESE swell crosses S/SSW wind-wave, creating an awkward, uncomfortable motion even though wind speeds stay moderate under 15 knots.

📋 Latest outlook: Great Wednesday; building swell-wind wave conflict later week

GOWed Aug 26

Best day of the period: light 4-12 knots west/northwest winds and calm 2.7 feet seas at 6-7 second periods from the southeast. Ideal window is 11:00 AM to 2:00 PM. Excellent visibility and high confidence.

CAUTIONThu Aug 27

Manageable early, but winds build to 15-17 knots south with gusts over 20 knots by evening and seas climb toward 4.7 feet. Late evening (9:00 PM-11:00 PM) brings a confused cross-sea as ESE swell crosses SSW wind-waves - use caution and plan an earlier return.

NO-GOFri Aug 28

NO-GO through midday: confused cross-sea as ESE swell meets SSW wind-waves, with steep 4-5 feet seas at 5-6 second periods and gusts to 21 knots. Conditions improve after 3:00 PM as winds ease and the cross-sea relaxes - avoid the water until then.

Wednesday offers clean, light-wind conditions ideal for boating, but confidence deteriorates through Thursday night into Friday as a crossing sea state develops between southeast swell and south/southwest wind-waves. Friday's confused cross-sea combined with steep short-period chop makes for an unsafe, uncomfortable ride through midday, improving only in the afternoon.

CAUTIONWed Aug 26

Light north-northwest winds under 11 kt all day, but a persistent 5.0-5.5 ft SSW swell at 9-second periods keeps seas choppy and uncomfortable. Caution advised throughout Wednesday with no clear improvement window.

CAUTIONThu Aug 27

Overnight chop clears by 3:00 AM, giving way to a better afternoon with light 7-11 kt northwest winds and 4.1-4.7 ft southwest swell at 8-9 second periods. Wave period forecasts are uncertain, so exercise caution despite the improved outlook.

CAUTIONFri Aug 28

Friday looks like the best day with light winds and longer-period 10-11 second swell making for smoother seas through the afternoon. But wave period forecasts are highly uncertain, and evening brings building swell and shifting south-southwest winds - aim to return by 6:00 PM.

Winds stay light and manageable across all three days, generally under 11 knots from the northwest. The issue is wave steepness - southerly swell in the 4.5-5.7 ft range is creating uncomfortable, choppy seas that keep every day in caution territory despite the calm wind.

NJ Offshore Fishing Report

Daily offshore conditions across 3 zones, rebuilt every morning.

📋 Latest outlook: Great Wednesday; building swell-wind wave conflict later week

GOWed Aug 26

Best day of the period: light 4-12 knots west/northwest winds and calm 2.7 feet seas at 6-7 second periods from the southeast. Ideal window is 11:00 AM to 2:00 PM. Excellent visibility and high confidence.

CAUTIONThu Aug 27

Manageable early, but winds build to 15-17 knots south with gusts over 20 knots by evening and seas climb toward 4.7 feet. Late evening (9:00 PM-11:00 PM) brings a confused cross-sea as ESE swell crosses SSW wind-waves - use caution and plan an earlier return.

NO-GOFri Aug 28

NO-GO through midday: confused cross-sea as ESE swell meets SSW wind-waves, with steep 4-5 feet seas at 5-6 second periods and gusts to 21 knots. Conditions improve after 3:00 PM as winds ease and the cross-sea relaxes - avoid the water until then.

Wednesday offers clean, light-wind conditions ideal for boating, but confidence deteriorates through Thursday night into Friday as a crossing sea state develops between southeast swell and south/southwest wind-waves. Friday's confused cross-sea combined with steep short-period chop makes for an unsafe, uncomfortable ride through midday, improving only in the afternoon.

Daily offshore conditions across 2 zones, rebuilt every morning.

📋 Latest outlook: Good Wednesday, but wind-wave/swell cross-seas build Thu-Fri

GOWed Aug 26

Excellent conditions all day with light 5-12 kt winds and calm 2.5-foot seas at 6-8 second periods. Best window is 12:00 PM-2:00 PM when winds drop to just 5-6 knots. Great day for boating.

CAUTIONThu Aug 27

Good morning and afternoon with light-to-moderate south winds and 2.5-3.4 foot seas. After 5:00 PM a confused cross-sea forms (ESE swell crossing S wind-wave) plus a steep wind-wave chop with gusts to 22 knots - exercise caution or head in early.

CAUTIONFri Aug 28

Morning through early afternoon has a confused cross-sea (ESE swell crossing S wind-wave) with choppy 4.3-4.6 foot seas despite modest winds. Conditions ease markedly after 3:00 PM as winds go light and seas settle - wait until afternoon to head out.

Wednesday is the standout day with light southwest-to-northwest winds under 12 knots and gentle 2.5-foot seas at 6-7 second periods. Thursday and Friday both see a confused cross-sea develop as SE/ESE swell crosses S/SSW wind-wave, creating an awkward, uncomfortable motion even though wind speeds stay moderate under 15 knots.

Boating forecast FAQ

What is a boating forecast?

A boating forecast is a marine weather forecast focused on the conditions that matter on the water — wind speed and direction, wave height and period, and overall sea state — for a specific spot and time window. SeaLegs AI turns those raw conditions into a simple GO, CAUTION, or NO-GO rating so you can decide at a glance whether it's a good day to head out.

What do GO, CAUTION, and NO-GO mean?

GO means conditions are favorable for most recreational boats. CAUTION means conditions are marginal — manageable for experienced boaters in capable vessels, but worth a closer look at the wind and wave timing. NO-GO means conditions are hazardous for small craft and the trip is best postponed.

How often does the boating forecast update?

Each spot card shows live conditions that refresh as new marine model data is published. For a forecast tailored to your exact launch point, download the SeaLegs AI app and add your own spot.

Can I get a boating forecast for my own spot?

Yes. The featured spots are examples. In the free SeaLegs AI app you can add any location on Earth and get an AI boating forecast with GO/CAUTION/NO-GO guidance, fishing reports, and trip planning for that exact spot.
