Marine Forecast for FAD Buoy 1 Sep 11–13, 2026
📋 Friday's brief chop eases into a calm, boat-friendly weekend
A brief bout of steep, choppy wind-wave conditions hits overnight into early Friday morning with 3-second period seas near 3 feet and gusty 16-23 knot SSW winds. Conditions steadily improve after sunrise, with calmer 8-12 knot winds and smaller seas taking over by midday. Best to avoid the first few hours and wait for the afternoon window.
Saturday is calm and favorable throughout, with light 3-9 knot winds and small 1.3-1.9 foot seas at 3-4 second periods. Midday brings near-calm winds before a light southerly breeze returns in the afternoon. A great day to be on the water.
Sunday brings the smoothest conditions of the forecast, with light 2-6 knot winds and gentle 0.9-1.2 foot seas at 4-second periods all day. No rough patches are expected - a great day for boating from morning through evening.
Friday brings a short window of steep wind-driven wave chop from the SSW that overlaps with SSW swell, creating an uncomfortable but survivable few hours around midnight into early morning, while winds stay manageable all day. Saturday and Sunday see winds and seas both ease steadily, delivering calm, well-organized conditions ideal for recreational boating. Model confidence is high (95%) across all three days, giving good reliability to this outlook.

About this Gulf of Mexico forecast
This forecast tracks conditions at FAD Buoy 1, a fish aggregating device anchored in the open northern Gulf of Mexico that concentrates mahi-mahi, tuna, and wahoo around it. As a fixed open-water point well offshore, it is an honest read on what the open Gulf is actually doing — beyond the sea buoy, past the beach forecast, where conditions can shift fast.
The outlook below updates every morning from the latest marine model data, with a plain GO / CAUTION / NO-GO call for each day — the same AI rating used in the SeaLegs AI app.
Reading open-Gulf conditions
Gulf seas are typically shorter-period than open-Atlantic or Pacific swell — wind-driven chop that builds quickly when a breeze sets in and lays down almost as fast when it quits. That makes the Gulf less forgiving of a deteriorating afternoon than the raw wave heights suggest: 2 feet at 4 seconds is a wet, pounding ride in most center consoles. Watch the trend within each day on the cards above, not just the daily headline.
Summer patterns hinge on the sea breeze and afternoon thunderstorms; frontal season flips the Gulf rough for days at a time. When the outlook shows a building trend late in the day, plan to run early and be headed in before it arrives — the open Gulf gives you nowhere to hide.
FAD Buoy 1 forecast FAQ
How is the sea at FAD Buoy 1 today?
As of Sep 11, 2026, the SeaLegs AI verdict for FAD Buoy 1 is CAUTION. Friday starts with a rough patch: steep wind-wave chop develops around midnight into the early morning hours, with SSW swell crossing SSW wind-wave creating a confused, uncomfortable short-period sea near 2.8-3.0 feet at just 3 seconds, paired with 13-16 knot S/SSW winds gusting up to 23 knots. This steep chop period lasts about 3 hours before easing, and conditions improve steadily through the day as winds settle to 8-12 knot SW/SSW and seas drop to 2.0-2.6 feet at 3-second periods from the SSW/S. Exercise caution overnight into early morning, but afternoon and evening are more manageable for boaters willing to wait out the rough start.
What is a FAD, and why forecast one?
A FAD (fish aggregating device) is a buoy anchored in open water that concentrates pelagic fish like mahi-mahi, tuna, and wahoo. Because it sits at a fixed point well offshore, it doubles as a reliable reference for what open-Gulf conditions are really doing.
How often is this Gulf of Mexico 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 when it was last generated.
What do GO, CAUTION, and NO-GO mean?
GO means conditions are favorable for most recreational boats. CAUTION means marginal — in the Gulf, pay special attention to the within-day trend and afternoon wind. NO-GO means conditions are hazardous for small craft and the trip is best postponed.
