South Padre Island CG Station, TX Daily Water Report — August 23, 2026

Sailing and diving own Sunday at South Padre Island CG Station, posting 9.2 and 9.1, with fishing and boating both a solid 7.4 and wildlife at 7.8. Kayaking sits at a more cautious 6, and surfing is the clear leftover at 4.5 on a short, small sea. Those figures are suitability scores, not a safety declaration. Forecast and current conditions agree on a cloudless, rain-free stretch. Air runs 26.4 to 31.9 C and will feel nearer 36 C with a dew point around 24 C, so heat is the real tax of the day. A representative southeast wind near 14 knots stays fairly consistent through the lighter 3-to-14-knot range, with the strongest gust, 16.7 knots, held until 22:00. Pressure is stable near 1014 hPa. Atmospheric visibility stretches 26.5 km and UV sits at 7.25—a sun problem, not an underwater-clarity one. Marine guidance keeps waves between 0.3 and 0.4 meters, calmest near 09:00 at 0.32 meters, with a 0.22-meter swell from 115 degrees at only 4.9 seconds and even shorter wind waves on top. Surface water is 29.6 C, even with average. A 0.4 m/s current sets toward 333 degrees. That meek sea plus the breeze and empty sky is exactly what lifts sailing; the same height and period is why surfing stays muted. Diving’s mark tracks the light wind, small waves, and warm water. Boating and kayaking share the wind-wave-current-and-dry logic, with kayaking more sensitive to that southeast push. Fishing’s 7.4 leans on solunar timing, tide state, steady pressure, and wind—not on the moderate chlorophyll reading of 0.52 mg/m3. Wildlife’s 7.8 comes from solunar timing, the evening low, and the wind. NOAA tides give a 0.46-meter high at 05:20 and a near-zero low of -0.01 meters at 18:51. The cleaner fishing and wildlife windows sit on the morning major period, 08:35 to 10:35 after the 07:05 sunrise, and again from 20:35 to 22:35 once the flats have drained—though that later slot collides with the night gust. A waxing gibbous moon, 76 percent lit, rises at 17:09. Yesterday’s reconstructed scores were nearly identical for sailing, a tick higher for diving, a hair softer for fishing, and noticeably lower for wildlife and kayaking under similar wind and pressure. The week ahead looks like a photocopy: mid-20s to low-30s C, peak winds 13 to 15 knots, almost no rain chance, and waves still 0.3 to 0.5 meters. Best bet: take the morning breeze and that 09:00 sliver of smallest water if you are sailing or diving, and leave the board home.
