CatchWindow fishing intelligence

Matagorda Bay Entrance Channel, TX Daily Water Report — August 27, 2026

The entrance channel is a strong go for fishing and boating today, while paddle craft and divers should also find a solid morning window before the southerly breeze firms up. Sailing is the standout play, scoring an 8.8, and the data backs it up: a steady southerly around 9 knots with gusts to 15, clear skies, and sub-half-meter waves mean you can reach planing speed without white-knuckling the tiller. For boaters and divers, both scoring 7.8, the calmest conditions arrive near 13:00, when wave heights bottom out around 0.32 meters. The ocean current here is modest, pushing northward at 0.6 m/s, but that’s manageable. Fishing scores a solid 6.9, helped by a waxing gibbous moon that’s nearly full, and solunar minor periods bookending early morning and early evening. The pressure is stable, winds are moderate—far better than the 12-plus knot days earlier this week, when fishing sat at 6.4 and 6.8. The water temperature anomaly is only half a degree below average, and those winds are fanning a light chop that should keep the channel oxygenated. Surfing, at 4.9, is a hard pass: short-period wind waves at 2.95 seconds won’t hold a face for long, and the swell is a whisper. Wildlife watchers might land a 6.5, but the morning minor period will be your best bet for activity near the surface. Compared to yesterday, when boating hit 8.2 with slightly lighter winds, today’s sailing potential is actually a touch higher thanks to that lunchtime lull. The southerly builds through the afternoon, climbing past 12 knots by evening, so afternoon kayakers—scored 5.8—should stick close to shore or plan an early return. Divers lose a few points from Monday’s 7.7, but the visibility at 17.7 kilometers in the air isn’t the same as underwater clarity, and you aren’t fighting swell. Looking ahead, Thursday and Friday tighten up further: wave heights dip as low as 0.1 meters on Friday, and peak winds settle near 11-12 knots. The weekend then kicks back up toward 0.5-meter waves and slightly stronger gusts. For a memorable best-bet, aim your morning launch toward the solunar peak at 11:45 and let that stable breeze carry you into a midday bite that the forecast favors.
