MRMTC Offshore OpenMarine Weather — Manasquan Inlet to the Canyons
The MRMTC Offshore Open 2026 (Aug 29 – Sep 5, 2026) is fishing out of Brielle, New Jersey. Here are the live inshore, midshore, and canyon conditions for the run — refreshed every morning.
Tournament Location
The Offshore Open is fished on the crew's own schedule — two separate days or a single overnight inside the week — so the call that matters is which window is clean from the inlet all the way to the canyon. This page reads the run in three zones rather than giving one coastwide number. The live day-by-day GO / CAUTION / NO-GO cards are up top; here is the map, the context, and the latest one-line outlook for each zone.
Hudson Canyon
OffshoreThe Hudson Canyon — the East Coast's largest submarine canyon and the offshore ground the Offshore Open is decided on, roughly 80 nautical miles out of Manasquan Inlet. Pan and zoom the chart, and switch layers to read the water.
Manasquan Inlet
40.102, -74.033
The fleet's gateway to the Atlantic and the one piece of water every boat crosses twice. A narrow, jettied inlet where an ebb against an onshore swell stacks the bar up steep — read it against the tide before you commit to the run.
Great boating weekend—calm winds and small, gentle seas all three days
This is a strong GO stretch with light winds under 11 knots and small waves staying under 3 feet all three days. Wave periods run 4-6 seconds, which is short but the waves are small enough to stay comfortable and well-behaved throughout the forecast window.
Manasquan Inlet — Friday, Sep 11 · GO
A great day out on the water with light winds and small, gentle seas throughout. Morning brings 8-9 knot north winds easing to near-calm by midday, with 1.6-1.7 feet seas at 4-5-second periods from the east. The best window is midday into afternoon (12:00 PM-4:00 PM) when winds drop to just 2-5 knots and seas settle to 1.4-1.6 feet at comfortable 5-second periods from the southeast — ideal conditions for any recreational activity on the water.
Manasquan Inlet — Saturday, Sep 12 · GO
Another good day for boating, with a very calm start giving way to a steadier breeze by afternoon. Overnight into mid-morning winds stay under 5 knots with tiny 1.1-1.2 feet seas at smooth 6-second periods, while afternoon and evening bring a more consistent 9-10 knot southeast to south-southeast wind with gusts to 18 knots and seas building gradually to around 2.2-2.4 feet at a shorter 4-second period. Conditions remain comfortable and manageable all day, with the smoothest ride found in the early morning hours.
Manasquan Inlet — Sunday, Sep 13 · GO
Conditions remain favorable with light-to-moderate south to southwest winds easing through the day, from around 10-11 knots in the early hours down to just 3-5 knots by afternoon. Seas start the day at their largest for the weekend, near 2.4-2.6 feet at a short 4-second period from the southeast, gradually smoothing to 1.7-1.9 feet at a more comfortable 5-6-second period by evening. Afternoon and evening offer the calmest, most pleasant conditions of the day for anyone heading out.
Triple Wrecks
39.602, -73.028
The mid-shelf wreck complex about 55 nautical miles out, on a more southerly heading than the canyon run rather than a stop along it — a shorter-range option when the canyon window shuts. The honest read on what the middle grounds are doing.
Great Friday; weekend brings choppy wind-driven seas
Friday offers the best conditions of the period with light winds and gentle seas, while Saturday and Sunday see a steepening wind-wave chop develop on top of the underlying swell, warranting caution. A Sunday afternoon rain shower adds another reason to plan around the timing on that day.
Triple Wrecks — Friday, Sep 11 · GO
Friday is the pick of the week with light winds and gentle, well-organized seas throughout. Winds start near 8-9 knots west-southwest overnight, swing north-northeast and peak around 15 knots with gusts to 20 knots between 7:00 AM-9:00 AM, then ease dramatically to near-calm 1-4 knots by midday through evening. Seas stay a comfortable 2.2-3.5 feet at 5-6 second periods from the south/SSE all day, making for smooth, easy conditions - the 1:00 PM-5:00 PM window is essentially flat calm.
Triple Wrecks — Saturday, Sep 12 · CAUTION
Saturday starts quietly with light 5-11 knots east winds and small 1.9-2.2 feet seas at 5-6 second periods from the SSE, but through the afternoon and evening a steep wind-wave chop builds as SE winds strengthen to 13-14 knots with gusts to 17 knots, riding on top of the existing SE swell and shortening/steepening the sea for about 5 hours. Since the wind-wave and swell are both coming from the same SE sector, this isn't a crossing sea, but the added wind chop makes the ride noticeably choppier and less comfortable than the calm morning. Plan to be off the water or exercise extra caution during the evening hours when the chop peaks.
Triple Wrecks — Sunday, Sep 13 · CAUTION
Sunday brings a more persistent steep wind-wave chop lasting roughly 9 hours as SSW-SW winds of 11-13 knots with gusts to 16 knots kick up a wind-wave that sits at an angle to the underlying SSE swell, producing an awkward, confused motion with no single comfortable heading - the SSE swell crossing the SSW/SW wind-wave. On top of that, 0.56in of rain is expected, likely reducing visibility and adding to the unpleasant conditions, particularly from late morning through the evening. This is a day to use real caution, watching timing closely and being ready to shorten or postpone the outing if the chop and rain arrive together.
Hudson Canyon
39.552, -72.407
The East Coast's largest canyon and the nearest true canyon to Manasquan Inlet — where an overnight trip is won or lost on white and blue marlin, bigeye and yellowfin. Fully exposed, so weight swell period as heavily as height.
Choppy patches all weekend keep this a caution-only stretch
Friday 2:00 AM to 11:00 PM offers the steadiest conditions, with light 3-16 knots north winds and 2.4-4 feet seas at 5-second periods from the south once the early cross-sea clears out.
Hudson Canyon — Friday, Sep 11 · CAUTION
Winds stay light out of the north at 3-16 knots, but early on a SSW swell crosses an NE wind-wave for a confused, awkward chop through about 2:00 AM. Conditions settle after that into steadier 2.4-4 feet seas, though the brief cross-sea keeps today at caution.
Hudson Canyon — Saturday, Sep 12 · CAUTION
Winds are gentle at 6-13 knots from the ESE with mild gusts, and seas run 1.9-2.6 feet at 6-second periods from the SSE. A 6-hour stretch of steep wind-wave chop develops on top of otherwise good conditions, keeping this a caution day despite an overall favorable base.
Hudson Canyon — Sunday, Sep 13 · CAUTION
SW winds of 11-16 knots with gusts to 20 knots combine with 2.8-3.7 feet seas at 5-second periods from the south, plus a soaking 0.58in of rain. A long 10-hour bout of steep, choppy wind-wave conditions makes for an uncomfortable ride, warranting caution all day.
Manasquan Inlet tides
Every trip starts and ends at the inlet, and an outgoing tide against an onshore swell stands the bar up fast — read the run against the tide before you commit.

The Offshore Open is the Manasquan River Marlin & Tuna Club's premier offshore tournament — now in its 46th year and the biggest offshore event out of Manasquan Inlet. Boats run out the inlet and push offshore to the Hudson Canyon and the wider Northeast canyons chasing white and blue marlin, bigeye and yellowfin tuna, with nightly weigh-ins at the Brielle Yacht Club.
The format is what makes the weather call decisive: each boat fishes either two separate days or one overnight trip at a time of its own choosing during the week — so the tournament is won as much on picking the right window as on finding the fish. Because the fleet fishes a wide band of water, this page reads conditions across three zones at once: inshore at the inlet, midshore over the wrecks, and offshore at the canyon. Each zone gets a plain GO, CAUTION, or NO-GO call, updated every morning from the latest marine model data — the same AI rating used in the SeaLegs AI app.
Reading the run from Manasquan Inlet to the Hudson
The canyon run out of Manasquan is a genuine offshore commitment — roughly 70 to 85 nautical miles each way depending on where along the canyon you fish, with nowhere to duck in once you're past the shelf. That distance is the whole argument for the three-zone read: a clean inlet and flat wrecks at dawn say very little about what the canyon edge is doing twelve hours later, and an overnight crew is committed to the forecast on both ends of the trip. Weight swell period alongside height — a long-period 6-second-plus swell rides very differently from short, stacked wind chop at the same wave height, and the warm-eddy edges where the fish set up are also where wind-against-current stands the sea up steep.
The inlet itself deserves its own look. Manasquan is narrow and jettied, and a hard outgoing tide meeting an onshore swell can make the bar rough and steep even when the open-water forecast reads moderate — which matters most on the ride home, tired, at the end of an overnight. Summer here also runs on the sea breeze: mornings are often the calmest water of the day, a south or southeast breeze fills in around midday and can build through the afternoon, and pop-up thunderstorms are a daily risk. Pick the window that stays open across all three zones in both directions. This page is a planning aid, not a substitute for the official NWS coastal waters forecast and marine warnings — always check those before you leave the dock.
MRMTC Offshore Open forecast FAQ
What are the marine conditions at the Northeast canyons today?
As of Sep 11, 2026: Manasquan Inlet — GO; Triple Wrecks — GO; Hudson Canyon — CAUTION. Every rating is rebuilt each morning from the latest marine model data.
When and where is the MRMTC Offshore Open?
The Offshore Open is hosted by the Manasquan River Marlin & Tuna Club out of Manasquan Inlet, New Jersey, with the 2026 edition fishing August 29 through September 5. Registration is the evening of August 28 at Safe Harbor Crystal Point, and weigh-ins are held nightly at the Brielle Yacht Club.
How does the Offshore Open format work?
Each entered boat fishes either two separate days or one overnight trip at a time of its own choosing during the tournament week, rather than every boat fishing the same fixed days. That flexibility puts the weather window at the centre of tournament strategy — which is exactly what the three-zone board on this page is built to help you read.
What's the run from Manasquan Inlet to the canyons like?
It's a real offshore commitment — roughly 70 to 85 nautical miles each way to the Hudson Canyon — the nearest true canyon to Manasquan Inlet — depending on where along the edge you set up, with no shelter once you're past the shelf. Conditions can differ sharply between the inlet, the midshore wrecks, and the canyon edge, which is why this page reads all three zones separately rather than giving one coastwide number.
What species are caught in the Offshore Open?
The tournament is fished for white and blue marlin plus bigeye and yellowfin tuna in the Northeast canyons. Weigh-ins are held nightly at the Brielle Yacht Club; check the official tournament rules for the current category and release requirements.
How often is this forecast updated?
The three-zone board is rebuilt every morning from the latest marine model data, and each SpotCast card refreshes live in your browser. The date stamp above the outlook shows exactly when it was last generated.
What do GO, CAUTION, and NO-GO mean?
GO means conditions are favorable for most recreational offshore boats. CAUTION means marginal — manageable for experienced crews in capable vessels, but check the wind, swell period, and timing closely. NO-GO means conditions are hazardous for small craft and the trip is best postponed.
Can I get a forecast and fishing report for my own canyon numbers?
Yes. In the free SeaLegs AI app you can drop a pin on any spot on Earth — your own canyon numbers, a midshore wreck, or the inlet — and get the same AI-rated marine forecast, trip planning, and DeepCast AI fishing reports with SST breaks, chlorophyll edges, and structure.
