September Fishing on the Florida Gulf Coast

Artificial Lure here with your Gulf of Mexico Florida fishing report for Wednesday, September 3, 2025.

Sunrise set the sky ablaze at 7:04 a.m., and we’re looking at about 12 hours and 38 minutes of daylight before sunset at 7:42 p.m. Today’s weather along the Gulf is classic September: marginally cooler than the dog days but still humid and warm. A stalled frontal boundary is bringing scattered showers, especially in southern sections, so watch for pop-up thunderstorms. The heat index will creep toward triple digits, especially in the afternoons. Winds are moderate, mostly from the southeast, settling down after a breezy start to the week. The first round of fall king tides is ramping up, so expect some minor coastal flooding close to high tide, especially in estuaries and low-lying spots.

Tidal action is on the gentle side: the tidal coefficient around Sanibel and the central Florida Gulf only creeps from the mid-30s early to about 47 by day’s end—meaning weaker currents and a less pronounced difference between high and low tides. This makes for easier fishing from small craft and kayaks, though savvy anglers know moving water is always better for bites.

September’s mild temp drop means fish are stirring. Offshore, grouper and snapper are moving into shallower waters—65 feet out is prime for big red grouper and consistent lane and mangrove snapper. Madeira Beach captains report solid mackerel and trout action around hard bottoms and artificial reefs, with Spanish and king mackerel blitzing bait pods. Reports from Sarasota, Tampa Bay, and Tierra Verde echo the trend: both live bait and big silver spoons are scoring fish, particularly for mackerel and trout. The gag grouper season is open for just two weeks—if weather allows, grab that rare shot.

Inshore, snook are transitioning off beaches and Gulf passes, heading back into the back bays and flats. Snook are on the move and hungry, hanging by oyster bars, mangrove shorelines, sandy potholes, and any structure you can cast to. Sanibel and Pine Island Sound are seeing midsize linesiders feeding aggressively, mostly on live pilchards, finger mullet, and pinfish, but larger swim baits and bucktail jigs are getting hits too. Even though snook season is still closed, catch-and-release action is excellent.

Trout are active across grass flats, especially near deep holes and inside bay cuts where tidal movement pushes bait. Most catches have landed on DOA shrimp, paddle tails in pearl or chartreuse, and Gulp! baits rigged under popping corks. Early morning and dusk are prime, with some bigger trout appearing on topwater plugs.

For bait, live pilchards, threadfin herring, and scaled sardines are best for everything from snook to snapper, but artificial lures like silver spoons, MirrOlure Twitchbaits, and soft plastics in natural “greenbacks” are getting it done. Mackerel and bluefish are smashing fast-moving spoons along color breaks and bait balls near passes.

Hot spots this week:
- **Sanibel Island:** Especially the causeway piers and the flats southeast of Blind Pass are loaded with snook and trout, and snapper are thick under docks and near deeper mangrove edges.
- **Madeira Beach Reefs:** Spanish mackerel, kingfish, and plenty of snapper are working the artificial reefs and ledges—use live bait for quantity or big spoons for fast action.

Offshore, look for pelagics like bonito and the occasional mahi as pods of bait push south. If you're after sharks, several charters from Tampa Bay to St. Petersburg report good numbers—fresh-cut mullet or bonita slabs are the ticket.

A quick reminder: always check regs before you keep, gag season is brief, and snook are still off-limits for harvest. With king tides rising through the week and mild weather patterns, it’s the perfect window to wet a line and see what Florida fall fishing is all about.
