Texas upper coast snook bite building as fall transition nears
Water temps are still running summer-warm across the upper coast, 87.3 to 89.6°F this morning at the Galveston-area and Corpus-area CO-OPS stations, holding well above where late-September usually sits. Texas Fish & Game Magazine's look at the upper coast points out that Lower Laguna Madre gets most of the attention for snook, but the species pushes north along the Texas coast too, and Sport Fishing Mag reports Gulf snook are already feeding up as days shorten ahead of their move to winter holding water, with swimbaits like the Z-Man Mulletron and Diezel MinnowZ working on aggressive fish. Tides are rolling through an overnight high, peaking between roughly 2:32 and 4:47 a.m. CDT across the three stations, into an evening low near 6:27 to 6:51 p.m., setting up a falling tide through the afternoon.

That afternoon outgoing tide is worth building around: Sport Fishing Mag's piece on falling-tide fishing notes that outgoing current concentrates feeding activity at inlets and jetties, and with lows landing right at dusk this week, the jetty systems from Galveston down through Corpus should see the strongest window in the two hours before low water.
Water this warm won't hold all fall; expect it to start sliding as nights cool into early October, which is when the snook bite Sport Fishing Mag describes should sharpen further as fish stage for their seasonal move. Plan around the falling tide in late afternoon and early evening rather than the overnight high, and watch the moon — a waxing gibbous heading toward full will push slightly stronger tidal exchange into the weekend.
Context
Upper-80s water in late September is on the warm side for this stretch of the Gulf Coast, which normally starts cooling through the low-to-mid 80s by now; the fall transition described in the snook reports is just beginning rather than already underway here. Snook activity typically holds through the Texas coast into November before fish pull back toward Laguna Madre and other traditional wintering grounds, so the upper coast window highlighted by Texas Fish & Game Magazine is opening now, not closing.
