San Luis Pass, TX Daily Water Report — August 28, 2026

Today is a spectacular day for getting on the water at San Luis Pass, with near-perfect conditions for small craft and flat-water activities. Boating and kayaking are both scoring above a 9 out of 10, and diving is close behind at an 8. This is a rare window where the wind is practically a whisper, the heat is intense, and the Gulf is glassy. The key driver is a light easterly breeze that is holding steady around 2 knots this morning, with gusts barely registering. That is the calmest we have seen since at least August 22nd, when winds were blowing over 12 knots. The water is dead flat, with waves only 0.24 meters and a 3-second period, and the ocean current is negligible. If you have a kayak, paddleboard, or small skiff, the window from now through late afternoon is about as ideal as it gets—just be prepared for the heat, because a feels-like temperature of 40°C with zero cloud cover means you’ll want plenty of water and sun protection. The calmest moment looks to be around 7 p.m., when waves dip to 0.14 meters. Fishing scores a respectable 6.7, which is in line with recent days. The solunar major period from 12:24 to 2:24 p.m. might offer a little edge, and the low tide at 10:42 a.m. will concentrate any action in deeper cuts. The chlorophyll reading is elevated, but we cannot say what that means for fish activity on the flats here. Surfing remains a low 4.5—the swell is minimal and barely above 2 seconds, so not worth the drive. Compared to yesterday, the wind has dropped from over 8 knots to near nothing, making this the best boating day of the past week. The diving score holds steady at 8, which reflects the calm surface conditions and warm 31.5°C water, though underwater visibility from the surface is not accounted for in that score. Looking ahead, Friday through early next week stays quiet, with waves staying below half a meter and peak winds in the low teens. A slight chance of rain creeps in by Sunday, but nothing that would derail a trip. Your best bet today: launch before the midday sun bakes the pass, and you will have a rare, mirror-flat August afternoon to yourself.
