Texas Gulf Coast holds summer-warm water into late September
Water across the upper-to-middle Texas coast is still running summer-warm heading into the final days of September. NOAA's CO-OPS stations spanning Galveston to Corpus are reading 86.9°F, 84.6°F, and 87.3°F this morning, holding firmly in late-summer range for the Gulf coast. That warmth keeps the whole system on a summer clock even as the calendar turns toward fall.

These upper-80s readings should hold over the next few days. A stretch this warm typically only breaks with a real frontal push, and nothing in the current pattern points to one arriving immediately.
With a waning gibbous moon this week, morning and late-evening windows are the better bet, since surface temperatures in the upper 80s tend to slow activity through the hottest hours of the day. The next meaningful shift for this stretch of coast comes with the season's first real cool-down.
Context
Late September this far south on the Texas coast still runs on essentially a summer clock. Water in the mid-to-upper 80s is normal for the Galveston-to-Corpus stretch at this point in the calendar, and the real seasonal turnover, the cooling that triggers the fall pattern anglers wait for, typically arrives in October as the first strong cold fronts push through. Right now this coast is on schedule for the time of year, not early or late.
