High Island, TX Daily Water Report — August 27, 2026

Boating and kayaking are the clear winners today along the High Island coast, with a nearly flawless 9 out of 10 for the former and a strong 8.1 for the latter. The Gulf is putting on its best late-summer face: a representative southeast breeze around 6 knots keeps things moving without pushing you around, and those wave heights hover near a flat 0.22 meters for most of the day. Anyone who got tossed around by the 11.8-knot gusts on August 22 will appreciate how much more civilized this feels. The calmest stretch arrives around 9 p.m., when the wave heights drop to just 0.2 meters, but the entire daylight window is workable for anyone with a hull under them. Wildlife watchers should pay attention too—the 8.9 score reflects the lingering effects of very high chlorophyll levels and favorable solunar timing around midday. The morning minor feeding period runs from 6:06 to 7:06, which dovetails nicely with dawn at 6:28, giving early risers a two-for-one window. Fishing sits at a respectable 7.1, a solid notch above the 5.8 we saw on August 23, though the midday major solunar period from 11:36 to 1:36 may see increased activity despite the bright, 98-percent-illuminated moon overhead. The water temperature remains a bathtub-like 31.8 degrees Celsius, so push through the heat with plenty of hydration and sun protection—the UV index may be low, but the feels-like temp of 34.5 is no joke. Surfing suffers from those small, quick-period waves at 0.22 meters with a 2.8-second swell interval, offering little more than knee-high slop for anyone who absolutely needs a session. The diving score of 6.9 is decent but unremarkable, held back by that same flat water that makes for easy entry but limited underwater structure. The southerly swell direction from 193 degrees doesn't favor any particular break, so divers should find calm conditions for spearfishing or reef exploration, just don't expect crystal clarity. Tomorrow keeps the trend going with similar wave heights and slightly stronger wind peaking near 9 knots, then a minor bump in precipitation chances by Sunday. For today, the best bet is to launch early, soak up that gentle southeast breeze, and let the falling afternoon glass-off carry you home.
