Galveston Bay Entrance, North Jetty, TX Daily Water Report — August 28, 2026

This is a boater’s and kayaker’s day, full stop. With a representative wind of just 3 knots from the SSE, waves averaging a flat 0.2 meters, and a peak gust barely brushing 15 knots late afternoon, the North Jetty is serving up conditions that rarely align this cleanly. The boating score of 9.3 and kayaking score of 8.8 are the highest we’ve seen in the past week, and they reflect the reality: a glassy morning, a light seabreeze that never turns nasty, and a falling tide that will clean up any residual chop by midday. The tradeoff comes for surfers, who get a score of 4.5 on a 3-second wave period. That’s a lake, not a lineup. The swell is barely 0.18 meters from 173 degrees, and the wind waves are effectively nonexistent. Diving sits at a 6.8, which is consistent with recent days—the water is bathtub-warm at 31.4°C with a slight positive anomaly, but the chlorophyll reading is very high, meaning you’ll be staring through green soup rather than clear blue. Visibility is the question no data point answers directly here, but bloom conditions generally mean milky water. Fishing scores a 6.4, which lands in the “worth the trip if you pick your window” zone. The full moon overhead, with major solunar activity from 12:23 to 14:23, coincides nicely with the outgoing tide this afternoon. The low at 22:45 will drain the flats, but the midday ebb will push bait and potentially larger fish past the jetty rocks. Compared to yesterday’s 6.2, it’s a slight uptick, though conditions remain average. Compared to recent history, the biggest shift is the drop in wind. Yesterday saw nearly 10 knots on average, and the day before that over 10. Today’s calm is a reprieve for anyone who wants to get offshore without a beating. The pressure is stable at 1017 hPa, and no rain is in sight. Heat is the real hazard—the feels-like temp hits 41.3°C, so bring more water than you think you need. Looking ahead, Saturday stays similarly calm but warms again, with winds picking up slightly Sunday and a chance of rain creeping in by Monday. If you’re chasing flat water, get it today. Best bet: slide a kayak off the north jetty on the morning ebb and let the full-moon tide do the work.
