Galveston Pier 21, TX Daily Water Report — October 4, 2026

Galveston Pier 21 gets a qualified green light today: best for sailing and diving, solid for boating and fishing, with paddlers needing to pick their moment rather than treating the bay like a flatwater pond. A NNE breeze around 10 knots, gusting 17 knots, is putting a little texture on the water without making it unruly. Waves run roughly 0.5 to 0.9 m, with the calmest conditions near 9 PM at about 0.54 m. That supports an 8.1/10 sailing outlook and an 8.2/10 diving outlook, helped by warm 28.9 C marine water and relatively modest seas. Those scores are suitability estimates, not a substitute for checking conditions at launch or entry; short-period wind waves at 2.2 seconds can still make for a busy surface. The most useful daylight window is early, from dawn through the 7:14–9:14 AM solunar major period. It lines up with the high tide having passed overnight and comes before the day’s low water at 5:41 PM. Fishing rates 7/10, aided by the solunar timing, rising pressure, tide state and available clarity inputs. The afternoon minor period, 1:44–2:44 PM, is another reasonable option, though the falling tide will be well established. Wildlife suitability is 7.9/10, with the low-tide approach and lighter-than-gusty wind profile doing some of the work. Boaters have a 7.4/10 day, but the pre-dawn gust peak—up to 21.4 knots around 3 AM—deserves respect, especially before daylight. Kayaking is more conditional at 6.4/10: the 0.22 m/s current toward 225 degrees and choppy short-period wave component favor sheltered routes and competent crews. Cloud cover is complete, humidity is high, and rain is possible through 3 PM despite representative precipitation near zero; the reported 13.5 km visibility is atmospheric, not a read on underwater visibility. Compared with yesterday, fishing, boating, kayaking and wildlife all improve, while sailing eases slightly from 8.2/10. The next three days look generally manageable, with lighter seas Tuesday and Wednesday before wind and waves build notably Thursday into Friday. Best bet: sail or fish the early-morning major window, then let the falling tide and evening calm decide whether the second outing is worth the dock lines.
