September 2025 — Naples / Marco Island: Snook Reopens Sept 1, Fall Fishing Begins, Excellent All Around. September is a early fall month with water in the 80–84°F range — snook season reopens (FL); bait migrations begin; redfish bulls show. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics for this month.
What’s Biting — September 2025
Primary targets this month: Snook, Redfish, Tarpon.
Snook
Snook are in the mangrove shorelines of the Ten Thousand Islands, Marco River, Rookery Bay, Naples Bay docks, Gordon Pass jetties, and Doctor’s Pass. Live pilchards, scaled sardines, and finger mullet are top live baits. Artificial: white DOA Bait Buster, MirrOdine, and walking topwaters at first and last light. Always check current FWC snook season dates — slot is 28–33″ Atlantic, 28–33″ Gulf, with seasonal closures.
Redfish
Redfish are in the back bays of the Ten Thousand Islands, Rookery Bay, Coon Key, Goodland flats, and the shorelines south of Marco Island. Cut bait, gold spoons, and soft plastics on light jigheads all produce. Match the tide and look for activity on shorelines with clean water.
Tarpon
Tarpon are mostly absent — a few resident fish in deeper backwater rivers and warm-water outflows.
Water Conditions & Patterns
Water temperatures are running 80–84°F. Snook season reopens (fl); bait migrations begin; redfish bulls show. Ten Thousand Islands fishing is heavily tide-driven — the backcountry rivers fish best on the first two hours of outgoing tide as bait flushes out. Beach tarpon are typically most active two hours either side of high tide.
Check the NOAA marine forecast and tide charts before launching. Wind direction matters more than wind speed for inshore fishing — east winds tend to push clean water in, while strong westerlies can muddy the bays.
Tactics & Tackle for This Month
- Mullet run. Massive bait migrations south along the coast trigger feeding frenzies — every predator follows. Target inlets, passes, and beach troughs.
- Topwater dawn. The fall coolness extends the topwater window — walk-the-dog baits (Heddon Spook, MirrOlure Top Dog) produce explosive strikes.
- Front timing. The 24 hours before a cold front pushes through are typically lights-out; the day after is often slow as fish reset.
September Outlook
Snook season reopens in Florida — bag a slot before the next closure. Mullet begin migrating south. First cold fronts of the year reset patterns.
Regulations Reminder
Snook: 28–33″ slot (Atlantic), 28–33″ slot (Gulf), one fish per angler per day; seasonal closures apply (typically Dec 15–Jan 31 and Jun 1–Aug 31 on Gulf; Dec 15–Jan 31 and Jun 1–Aug 31 on Atlantic — verify current FWC dates). Snook stamp required. Redfish: 18–27″ slot, one per angler per day (verify current FWC zone-specific rules). Tarpon: Catch-and-release only — tarpon over 40″ must remain in the water. Tarpon tag required to possess a fish for state record. Always verify the current FWC regulations at myfwc.com before your trip — sizes, bag limits, and season dates change.
