Gulf snook feed up as Mobile Bay eases toward fall transition
Water in Mobile Bay and the adjacent Gulf is still running warm for mid-September, with NOAA CO-OPS stations reading 85.8°F on the lower bay (station 8735180) and 87.6°F up the estuary (station 8736897) as of this morning. That heat is keeping the Gulf's fall transition on a slow build rather than a fast turn. Sport Fishing Mag's fall-transition coverage this week notes Gulf snook are beginning to feed up as days shorten and fish start working toward winter holding water, with aggressive swimbaits such as Z-Man's Mulletron or Diezel MinnowZ drawing strikes on active fish. Pensacola Fishing Forum members kept the board busy with general chatter this week, trail-camera checks and gear talk, while the seasonal snook pattern comes from Sport Fishing Mag's coverage rather than a local bite report. Both bay stations are riding a falling tide into the afternoon and evening, a stage many Gulf Coast anglers favor for moving current around structure.

What's next
With both stations still reading well into the mid-80s, look for the current warm pattern to hold over the next couple of days rather than flip quickly. The snook activity Sport Fishing Mag describes should keep building gradually, since a fall transition plays out over weeks rather than overnight; a stronger push typically follows once overnight lows start pulling surface temps down.
Plan around the falling tide: the lower-bay station (8735180) bottoms out near 4:53pm CDT and the upper-bay station (8736897) near 6:06pm CDT today, putting the last few hours of daylight right on moving current for anyone working structure and passes on the falling stage. With the moon in its First Quarter, tidal swings stay moderate rather than the wider ranges around new and full moons, which keeps current speeds manageable for swimbait and topwater presentations.
Heading into the weekend, watch for the first real cool front to nudge these readings down. That's typically the trigger for the fall pattern Sport Fishing Mag describes to take hold more firmly in Gulf estuaries.
Context
Water temps in the mid-to-upper 80s are normal for Mobile Bay and the Gulf in mid-September; this region runs later into its warm-water season than the Atlantic side of Florida, and the full fall snook pattern usually doesn't lock in until surface temps ease into the 70s. Right now conditions sit at the early edge of that transition, closer to late summer than true fall. Inshore action through this stretch typically favors moving water around passes and current breaks, matching the falling-tide window above. Expect the picture to sharpen as temperatures come down and more local reports come in over the next few weeks.
