Marine Forecast for Wilmington Canyon Nov 3–5, 2026
📋 Great Tue and Wed; skip Thursday's rough seas
GO all day. Light south winds of 2-10 knots with gusts to 14 knots and 1.7-2.0 foot seas at 6-second periods from the east-southeast. Visibility is 10+ nm and it stays dry, so any time works for a 12-hour trip.
GO all day. South winds of 6-12 knots with gusts to 15 knots, and seas building from 2.0 to 3.7 feet at 6-second periods from the southeast. Seas run moderate but manageable, visibility is excellent and it stays dry, so any time works.
NO-GO. South winds of 11-18 knots with gusts to 23 knots and seas of 3.8-5.3 feet at 6-second periods from the south-southeast turn steep and rough from late morning on. Seas are only workable until about 9:00 AM, which is no settled stretch for a 12-hour trip. Stay ashore.
Tuesday, November 3 from 9:00 AM to 8:00 PM is the pick, with light 5-knot south winds and gentle 2-foot seas at 6-second periods from the east-southeast.

About Wilmington Canyon
Wilmington Canyon notches the shelf edge roughly 75 nautical miles off Indian River Inlet and Ocean City, Maryland, the next canyon north of the Baltimore and a standard run for the Delaware, Maryland and South Jersey fleets. Where the bottom drops away, warm water and bait stack up — and with them yellowfin and bigeye tuna, white marlin, mahi and swordfish, with tilefish on the muddy edges.
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. Each day gets an honest GO, CAUTION, or NO-GO call — the same AI rating used in the SeaLegs AI app.
Reading conditions at Wilmington Canyon
The canyon sits at the edge of the continental shelf, where offshore swell arrives with nothing to soften it. Short-period seas that feel manageable at the inlet stack up steep over the shelf break, and a blow against the current makes it worse — so weight the swell 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. The warm shelf-break temperature edge where the fish set up is also where wind-against-current stands the sea up steep.
Plan the whole window, not just the departure. The run out is commonly 70 to 80 nautical miles each way — a long offshore day, often 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. Pick the day the window stays open on both ends, and always confirm the official NWS offshore waters forecast and marine warnings before you leave the dock.

How far offshore is Wilmington Canyon?
Wilmington Canyon lies roughly 75 nautical miles off Indian River Inlet, Delaware and Ocean City, Maryland, at the edge of the continental shelf. Depending on your inlet and cruise speed that is commonly a 70-to-80-mile run each way, with no shelter past the shelf.
What is the difference between Wilmington and Baltimore Canyon?
Wilmington is the next canyon north of the Baltimore, and slightly further east. Both are shelf-edge Mid-Atlantic canyons holding the same mix of tuna and billfish; which one a crew runs usually comes down to the inlet they leave from and where the warm edge has set up that week.
What fish does Wilmington Canyon hold?
The shelf-break canyon concentrates yellowfin and bigeye tuna, white marlin, mahi and swordfish along the warm temperature edge, with tilefish on the muddy bottom at the canyon's edges.
How often is this Wilmington 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, swell period, and timing closely. NO-GO means conditions are hazardous for small craft and the trip is best postponed.
