Florida Keys Fishing Report: Late September Paradise

Artificial Lure here with your Florida Keys fishing report for Saturday, September 20, 2025. Sunrise was at 7:11 AM and sunset’s set for 7:22 PM—plenty of daylight for chasing trophy fish in paradise. Today's tidal coefficient is riding high at 88, meaning we’ve got active tides and steady water movement. High tides hit around 3:16 AM and again at 3:14 PM, with lows in between. More current means more bait moving and game fish hunting, so plan your trips around these swings for best results (source: Channel Five Hawk Channel tide charts and Flamingo, Florida Bay tide tables). Weatherwise, it’s classic late September Keys—starting near 82°F at dawn, climbing to the upper 80s by midday. Winds are light out of the southeast, less than 10 knots, and water clarity is excellent. Calm seas will let you get out to the reefs, bridges, or flats without a fuss. The bite picks up with the incoming tide, so mid-morning through late afternoon should be prime time. Fish activity has been fantastic all week, with recent catches ranging from hefty mangrove snapper, Spanish mackerel, and swing-busting snook to big tarpon reported both after dark and at dawn (Spacefish and Suns Out Fishing reports). Offshore, dolphin (mahi-mahi) are migrating south—look for weed lines and birds, especially outside Tennessee Reef and around Islamorada Hump. Sailfish are starting to show early thanks to cooling waters, with king mackerel mixed in just outside the reef line. Inshore, the bridges lit up at dusk with snapper and mackerel, and the flats have produced bonefish, permit, and a few juvenile tarpon for the patient stalkers. Pinfish and pilchards are abundant in the shallows, which means the predators aren’t far behind. For bait, live pilchards and pinfish are the gold standards. If you’re bridge or marina bound, cut ballyhoo on a jig or freelined shrimp have been deadly. On the flats, a well-placed crab or shrimp will get the bonefish rooting. Artificial anglers, break out minnow baits—soft jerk shads rigged weedless, scented split-tail minnows, and small topwaters like Rapala’s Crush City Mooch Minnow mimic the real deal and fool wary snook and trout. Wired2Fish notes that adding scent gels to plastics is a proven difference-maker when the fish are playing hard to get. Hotspots you shouldn’t miss: - Channel Five Bridge, east side of Hawk Channel: Night and early morning sessions here have been electric for snapper and mackerel. Fish spinning gear with live pilchards, or bump a scented jerk shad near pilings. - Long Key Flats: Sunup brings bonefish cruising and some surprise permit. Downsize leader and quietly cast a live shrimp or crab. - Tennessee Reef: Dolphin and sailfish have been popping up along weed lines. Troll skirted ballyhoo or pitch live bait under birds for explosive action. - Islamorada Hump: Deep drop rigs and vertical jigs are putting big blackfin tuna and amberjack in the cooler. Bridge fishing after sunset has been reliable, with mangrove and lane sn This content was created in partnership and with the help of Artificial Intelligence AI.
