Snook feed up as Gulf Coast fall transition begins
Gulf water is still running warm this week, with our two Gulf Coast tide stations reading 83.7°F and 86.2°F this morning, typical late-September numbers before the real fall cooldown sets in. Sport Fishing Mag's fall coverage lines up with what we're seeing on the calendar: as summer's heat starts to break, Gulf snook feed up ahead of their push toward winter holding water, and aggressive fish are answering fast-moving swimbaits like the Mulletron and Diezel MinnowZ. Tides are swinging through a solid range today, a sign current is still moving well enough to concentrate bait along the usual fall travel lanes.

What's next
The next few days should keep favoring snook as water starts trending down from these high-80s readings; each cooling pulse this time of year pushes more fish out of the summer pattern and into the fall transition Sport Fishing Mag describes. Watch the tide swings closely: the stronger movement around the midday and early-afternoon highs, and the morning and evening lows, is when current stacks bait against structure and sharpens the bite.
With the moon in a waxing gibbous phase heading toward full, expect stronger tidal exchanges over the next several days, which typically widens the bite window around each tide change. Anglers planning a weekend trip should build around the afternoon high-tide push and the last couple hours of daylight, when falling light and moving water tend to overlap with peak snook activity during the fall transition.
Florida Sea Grant also flagged a rare rust tide algae bloom in Charlotte Harbor this month, distinct from red tide but still worth checking before launching in that stretch, since algae blooms can affect water clarity and bait behavior.
Context
Late September sits right at the seam between summer and fall on Florida's Gulf Coast, with water temperatures in the low-to-mid 80s typical for this point in the calendar; the pattern usually holds until a string of stronger cold fronts starts working temperatures down through October. Snook keying up ahead of their move to winter holding areas is an on-schedule seasonal shift, not an early or late one this year.
Charter operators on both coasts, including Naples Offshore Fishing Charters and Fin & Fly Charters out of Cocoa Beach, have tracked this kind of seasonal changeover through the year's cooler-to-warmer swings, and the current stretch fits that same rhythm. Tidal range and current strength through the transition tend to matter more than temperature alone for triggering activity, which is why timing the moving water matters most over the coming weeks.
