Snook push north as Gulf Coast flips into fall transition
Water on the upper Texas coast is still summer-warm, with CO-OPS stations near Galveston and Corpus Christi reading 86-90°F overnight into this morning, but the fall shift several writers have flagged is underway. Texas Fish & Game's look at the "Mystery of Upper Coast Snook" notes the species isn't confined to the Lower Laguna Madre and shows up well north of it, and Sport Fishing Mag's fall-transition piece has snook feeding up before pushing toward winter holding water, with swimbaits like Z-Man's Mulletron or a Diezel MinnowZ drawing strikes. Salt Strong's rundown of trusted fall lures backs that up, pairing bigger paddletails for redfish alongside snook as the seasonal switch flips.

With a full moon pushing tides, CO-OPS predictions across the three stations we're watching show an early high around 4:00-4:40 a.m. local sliding to a low near 9:30-10:30 a.m. Sport Fishing Mag's falling-tide piece is worth keeping in mind here: that outgoing push concentrates bait and predators, so the two to three hours after each morning high are the window to fish, before water goes slack toward midday.
If temps hold in the upper 80s to 90°F through the weekend, the snook bite Sport Fishing Mag describes should keep building as fish stage for their move toward winter grounds, and redfish should stay tuned into the same falling stages per Salt Strong's fall lure lineup. Worth watching whether that bite firms up further as mornings start to cool.
Context
Water sitting in the upper 80s to low 90s this late in September is typical for the middle Texas Gulf Coast, where the real cool-down and the strongest snook push toward winter refuges usually don't arrive until October. This reads as the early edge of that transition, a normal seasonal position for late September rather than an early or late one.
