Warm Gulf Stream Keeps Florida Keys Bite Rolling Into Fall
Water temperature at Key West is holding at 87.4°F this week, with Florida Bay reading a similar 86.7°F, keeping the reef and Gulf Stream fishery running on a summer pattern even as the calendar turns toward fall. ALL IN Key West reports the offshore and reef bite has stayed strong through the season, with steady numbers of fish coming over the rail on recent trips and live-bait trips producing especially well along the reef edge. Bud n' Mary's Islamorada Fishing Marina points to early summer through early July as the most productive stretch of the year in the Keys, and captains say that momentum has carried into September. CCA Florida also flags ongoing federal court activity over South Atlantic fishery management pilot programs, a storyline anglers along Florida's coast are watching closely this fall.

What's next
With water still sitting in the upper 80s, expect the current pattern to hold through the next several days rather than shift abruptly. The next high tide at Key West lands around 7:33 PM ET today, per NOAA CO-OPS station 8724580, giving late-afternoon and evening anglers a strong incoming push to fish around the turn. The moon is at First Quarter, building toward fuller phases over the coming week, which typically sharpens tidal flow and can trigger more aggressive feeding windows on the flats and along channel edges.
Elsewhere along the Gulf coast, Sport Fishing Mag notes that snook are beginning their fall transition as days shorten, moving toward winter holding areas, a shift Keys backcountry anglers can watch for as the season progresses. Plan around the incoming tide window this weekend, and expect reef and offshore conditions to stay consistent with recent trips as long as water temperatures hold near current levels.
Context
Late September in the Florida Keys sits at the tail end of the summer offshore and reef season, a stretch Bud n' Mary's and other Keys operations have historically pointed to as some of the most productive months of the year. Water in the upper 80s is typical for this time of year and keeps the Gulf Stream fishery active well past the point where more northern fisheries begin cooling down. The Keys typically hold this warm-water pattern into October before a more pronounced fall transition sets in, so current conditions read as on schedule for the season.
