Galveston Pier 21, TX Daily Water Report — August 25, 2026

Today's conditions at Galveston Pier 21 make it a fine day for most water activities, with boating and diving scoring particularly well. Boaters will enjoy an 8.1/10, aided by gentle winds from the south-southwest and manageable wave heights peaking at 0.6 meters. Meanwhile, divers can take advantage of a 7.9/10 score, thanks to stable barometric pressure and warm sea surface temperatures around 31.1°C, though visibility underwater wasn't specified. Fishing is decent, with a 7.2/10 score, bolstered by favorable solunar periods late morning and late evening, though anglers should be mindful of the low tide at 21:26 which might affect catch rates. The waxing gibbous moon at 90% illumination won't hurt evening efforts either. For the surfers, the day isn't quite as promising, with a score of 5.5/10. Waves are moderate, reaching up to 0.58 meters, but the short period and lack of significant swell might leave you longing for more challenging conditions. Kayakers and sailors face a mixed bag, with scores of 6.5/10 and 6.7/10 respectively. Light winds and manageable wave heights are good news, but stronger gusts reaching up to 17.5 knots earlier today might have left some choppy conditions in their wake. Looking back, today's conditions are similar to yesterday's, with a slight improvement in boating and kayaking scores. However, the wind has calmed down a bit since the bluster of the past few days, making for a more pleasant outing on the water. As we cast our eyes forward, expect rising winds over the next few days, peaking at 22.5 knots by August 28, accompanied by a higher chance of rain. For now, your best bet is to hit the water during the calmest period around midday, when the waves dip to their lowest and the sun is high in the sky.
