Florida Keys Bite Holds Onto Summer Momentum Into Fall
NOAA CO-OPS readings this morning put water at 86.9°F at station 8724580 and 86.5°F at station 8723970, full summer warmth still holding through the Keys as September closes out. Charter and shop reports back that up. ALL IN Key West called a recent Gulf-side trip "bananas," logging steady reef and bottom action mixed with strong offshore activity, and an earlier report from the same captain noted having to run extra lead to hold bottom against unusually strong current on the reef edge. Bud n' Mary's early-summer report described abundant bait and gamefish spread from the shallow flats out to the Gulf Stream, the kind of pattern that typically fades by now but is clearly still running. Coastal Angler Magazine's current Keys coverage centers on strong blue-water action offshore, another read on a warm-season bite that hasn't broken yet even as the calendar turns toward fall.

What's next
Station 8723970 shows a high near 8:50 AM and a low near 3:48 PM local time; station 8724580 shows a low near 1:32 PM. With the moon in a Waxing Gibbous phase and building toward full, expect stronger tidal push over the next few days, which should sharpen current-driven bites around reef structure and channel edges during the mid-morning high and early-afternoon low windows.
Captains have been logging consistent offshore and reef activity through the summer months, per ALL IN Key West, and nothing in this week's reports signals a break in that pattern yet. Anglers planning a trip this week should work the morning high tide push on the flats and shift to reef and channel structure around the early-afternoon low, when current is moving hardest and bait gets pinned against structure.
Watch for the first real cool-down signal in coming weeks. Water in the high 80s this late is a holdover, not the new normal, and once temperatures start dropping the flats-to-reef pattern described this week will begin shifting toward a more typical fall transition.
Context
Late September in the Florida Keys typically sits at the tail end of the warm-water season, with flats and reef patterns still resembling summer before the first fall cold fronts begin nudging water temperatures down. Readings in the high 80s this week are consistent with that late-summer holdover rather than an early or late anomaly for the region. Statewide, CCA Florida's ongoing coverage of reef-fish season management and allocation debates is a reminder that rules for several popular bottom and offshore species remain in flux this fall, worth checking current state regulations before keeping anything close to size or bag limits.
