Marine Forecast for Hudson Canyon Sep 4–6, 2026
📋 Building seas Sunday make this a NO-GO overall weekend
Light morning winds (9-11 knots W/WSW) and organized 3 feet seas give way to a steep wind-wave chop in the afternoon as northwest winds build to 14 knots gusting 19 knots. Conditions smooth out again after 9:00 PM. Best to time your trip for morning or evening.
Light north winds around 8-11 knots and small 2.5-2.8 feet seas make for a pleasant Saturday, but a steep wind-wave chop develops for about 6 hours creating an awkward, choppy ride. Best conditions are in the morning and early afternoon before the chop sets in.
Sunday is unsafe for boating with northeast winds building to 16-19 knots (gusts to 25 knots) and seas peaking near 5.3 feet at 5-second periods. The short-period, rough seas persist through the afternoon and evening. Stay off the water and wait for conditions to ease overnight.
Friday and Saturday offer generally light winds and manageable seas, though both days develop a steep wind-wave chop during a portion of the afternoon/evening that warrants caution. Sunday sees winds build to near 19 knots from the northeast with seas climbing to over 5 feet at 5-second periods, producing a rough, unsafe sea state that drives the overall NO-GO recommendation for this period.

About Hudson Canyon
Hudson Canyon is the largest submarine canyon on the U.S. East Coast, roughly 70–100 nautical miles offshore of New York Harbor — a premier run for tuna, marlin, and mahi, and one of the longest offshore commitments in Northeast fishing. At that distance there is no ducking back in when the wind comes up, so the forecast below is built around the two things that decide a canyon trip: wind against current and swell period.
The outlook updates every morning from the latest marine model data, and each day gets an honest GO, CAUTION, or NO-GO call — the same AI rating used in the SeaLegs AI app.
Reading conditions at Hudson Canyon
The canyon sits at the edge of the continental shelf, where the bottom drops away and offshore swell arrives with nothing to soften it. Short-period seas that feel manageable at the inlet stack up steep and close over the shelf break, and a south or southwest blow against an ebbing current makes it worse. When you read the days below, weight the wave period as heavily as the height: 5 feet at 12 seconds can be a comfortable ride out, while 4 feet at 5 seconds is a punishing one.
Plan the whole window, not just the departure. A canyon day is commonly a 16–20 hour round trip — an overnight for the tuna bite — so a forecast that opens calm and builds through the afternoon can close the door on the ride home. The three-day view above is exactly for that call: pick the day the window stays open on both ends.
Hudson Canyon forecast FAQ
How is the sea at Hudson Canyon today?
As of Sep 4, 2026, the SeaLegs AI verdict for Hudson Canyon is CAUTION. Friday starts calm with 9-11 knots west to west-southwest winds and steady 3.0-3.1 feet seas at 5-second periods from the southeast, comfortable conditions for most of the morning. By early afternoon into evening, winds shift northwest and build to 13-14 knots gusting up to 19 knots, and a steep wind-wave chop develops on top of the southerly swell for around 4 hours, making the sea state choppier and less comfortable even though wave heights only reach about 3.4 feet. Conditions ease again after 9:00 PM as winds drop back to 8-9 knots, so plan around the mid-afternoon window if heading out.
How far offshore is Hudson Canyon?
Hudson Canyon lies roughly 70–100 nautical miles offshore of New York Harbor, at the edge of the continental shelf. Depending on your inlet and cruise speed, that's commonly a 4–6 hour run each way.
How often is this Hudson Canyon forecast updated?
The forecast on this page is rebuilt every morning from the latest marine model data, and the 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 and wave timing closely. NO-GO means conditions are hazardous for small craft and the trip is best postponed.
