Cooling Temps and Fall Snapper Season Fire Up the Keys

What's biting

What's next

If the cooling trend ALL IN Key West describes holds, look for flats and reef activity to sharpen through the week as bait moves with milder air. Sport Fishing Mag notes Gulf snook begin shifting toward winter holding water as days shorten, a pattern that applies to Keys backcountry snook as fall settles in; swimbaits like a Z-Man Mulletron or Diezel MinnowZ are a good starting point once that push begins. Offshore, the newly reopened 14-day fall red snapper season, per CCA Florida and Saltwater Sportsman, gives boats an added target while the weather cooperates.

The waxing gibbous moon heading toward full over the next several days typically brings stronger tidal flow, worth planning flats and reef trips around this weekend.

Context

Late September in the Keys sits at the tail end of summer's flats and offshore peak, with water still in the mid-to-upper 80s°F, typical for this time of year ahead of fall's gradual cooldown. Captains describe this stretch as the turn toward the stronger fall and winter season, consistent with the shift ALL IN Key West is reporting. Regulatory attention this month has centered on red snapper management as the reopened fall season begins; anglers should check current state and federal regulations before harvesting.
