Marine Forecast for Norfolk Canyon Sep 19–21, 2026
📋 Choppy Saturday, clearing by Sunday afternoon
Saturday is a NO-GO: 12-17 knots ENE winds gusting to 24 knots stack up 2.8-5.4 feet seas at just 5-second periods from the ENE, a steep, choppy ride with no settled 12-hour stretch of good waves to work with.
Sunday starts rough with bad-to-caution waves through late morning, but conditions settle nicely and go GO from 12:00 PM onward into Monday. Winds are light at 6-12 knots SE; go only within that afternoon-onward window, not before.
Monday is the pick, with a long GO stretch from 12:00 AM to 7:00 PM: winds 7-16 knots NNW and 3.0-4.3 feet seas at 6-second periods from the east stay manageable. Waves turn cautious after 7:00 PM, so plan your trip before evening.
Sunday 12:00 PM to Monday 7:00 AM offers the best run, with steady 6-9 knots winds and waves settling to a comfortable 3.9-4.0 feet as the choppy morning seas fade.

About Norfolk Canyon
Norfolk Canyon is the southernmost of the major Mid-Atlantic shelf-edge canyons, cutting the edge roughly 65 nautical miles off Rudee Inlet and Virginia Beach and a little less from Wachapreague. It is the Virginia fleet's offshore run — yellowfin and bigeye tuna, white and blue marlin, mahi and swordfish along the warm edge, and one of the better tilefish grounds on the coast.
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 Norfolk Canyon
The canyon sits where the bottom falls away at the shelf break, and offshore swell arrives with nothing to soften it. Short-period seas that feel manageable inside the Chesapeake Bay mouth stack up steep and close over the edge, 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.
Two things make the Virginia run its own problem. The Chesapeake Bay mouth is a tide gate — a strong ebb against an onshore breeze stands the sea up in the approaches before you are even offshore — and the Gulf Stream edge sits close enough that a current-against-wind chop can build fast on the outside. Plan the whole window, not just the departure: the run is commonly 60 to 70 nautical miles each way, so a forecast that opens calm and builds through the afternoon can close the door on the ride home. Always confirm the official NWS offshore waters forecast and marine warnings before you leave the dock.
Norfolk Canyon forecast FAQ
How is the sea at Norfolk Canyon today?
As of Sep 19, 2026, the SeaLegs AI verdict for Norfolk Canyon is NO-GO. Saturday is a NO-GO: 12-17 knots ENE winds gusting to 24 knots stack up 2.8-5.4 feet seas at just 5-second periods from the ENE, a steep, choppy ride with no settled 12-hour stretch of good waves to work with.
How far offshore is Norfolk Canyon?
Norfolk Canyon lies roughly 65 nautical miles off Rudee Inlet and Virginia Beach, at the edge of the continental shelf, and a little less from Wachapreague. That is commonly a 60-to-70-mile run each way, with no shelter past the shelf break.
What fish does Norfolk Canyon hold?
The shelf-break canyon concentrates yellowfin and bigeye tuna, white and blue marlin, mahi and swordfish along the warm temperature edge, and it is one of the better golden tilefish grounds on the Mid-Atlantic coast.
Does the Chesapeake Bay mouth affect the run out?
Yes. A strong ebb through the bay mouth against an onshore breeze stands the sea up in the approaches before you reach open water, so a day that looks fine offshore can still be a rough first hour. Check the timing of the tide against the wind, not just the offshore numbers.
How often is this Norfolk 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.
What is the water temperature at Norfolk Canyon today?
As of Sep 19, 2026, the satellite-derived sea surface temperature at Norfolk Canyon is about 76.4°F, with chlorophyll around 0.31 mg/m³ (green shelf water). The SST and chlorophyll charts on this page are rebuilt every morning from the SeaLegs AI DeepCast satellite pipeline.
