Marine Forecast for Hudson Canyon Sep 11–13, 2026
📋 Choppy patches all weekend keep this a caution-only stretch
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.
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.
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.
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.

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.
