CatchWindow fishing intelligence

Coast Guard Sector Mobile, AL Daily Water Report — August 28, 2026

This is a day for getting out on the water. The full moon is overhead, the wind is barely a whisper, and conditions are about as settled as they get this time of year. Boating and kayaking score near-perfectly, fishing is excellent, and even diving is well above average. If you’ve been waiting for a window that feels like a gift, this is it. The story is the wind. A light NNW flow, representative around 4 knots and topping out under 8, keeps the surface glassy through the morning. Waves are negligible—just a 0.1-meter ripple with a 4-second period—and the swell is almost nonexistent. The marine layer is thin with only 27% cloud cover, visibility stretches over 13 kilometers, and barometric pressure is rising steadily at 1017 hPa. That’s a textbook setup for stability. The only tradeoff is the heat: air temperatures climbing toward 29°C with humidity near 90% will make it feel steamy, but the water is a bathtub-warm 32.3°C, which is nearly a full degree above average for late August. Fishing scores an 8.4, driven by the incoming high tide around 1:42 PM and a major solunar period peaking at noon. That midday window lines up nicely with the rising water and slackening currents. Kayakers and boaters should treat this as a green-light day—both activities score above 8.5—though boaters should note the 0.2 m/s northward current near the pass. Divers get a 7.6, which is consistent with recent days and reflects the warm water and calm surface; just don’t confuse the 13.6 km of atmospheric visibility with what you’ll find below. Surfers will find little to work with—the 4.5 score reflects the flatness—so leave the longboard at home. Compared to yesterday, wind has dropped from around 1.7 knots to a similar calm, but pressure is higher and the solunar alignment is stronger. The last few days have been consistently good for boating and kayaking, but today’s fishing score surpasses anything since August 23. Looking ahead, Friday brings a chance of showers and winds picking up to 10 knots, which will roughen the surface slightly. The weekend sees a warming trend with heat indices rising and a 50% chance of rain Saturday and Sunday. The marine forecast suggests waves staying under half a meter through Monday, but the settled calm of today won’t last. Best bet: If you can hit the water by late morning, you’ll be floating under a full moon’s influence with the Gulf flat as a table and the tide rising right on schedule.
