FLORIDA KEYS & MIAMI FISHING REPORT: Snapper Sizzle, Tarpon Tangle, Mahi Mahi Madness

Artificial Lure here with your Florida Keys and Miami fishing report for Friday, September 19, 2025. We woke up to calm, warm conditions this morning, with air temps right around 80 degrees and only a slight breeze ruffling the water—perfect for a day on the salt. Let’s break down the tides, starting in Miami. According to Tide-Forecast, we had a low tide at 1:51 AM, and the first high tide smacked in at 7:54 AM, bringing in a solid 2.69 feet. Around 2:13 PM, expect another low at 0.34 feet, then evening anglers can target the second high tide at 8:21 PM with a bump to 2.74 feet. Sunrise was at 7:08 AM, sunset is at 7:20 PM. Down in Conch Key, you saw similar patterns, with a high tide at 7:57 AM (1.94 ft) and another crest at 8:43 PM (1.52 ft). Key West’s high tides line up at 9:06 AM and 9:52 PM. That means the bite turns “ON” mid-morning and again near dusk—classic Florida fishing windows. Weatherwise, the forecast remains consistent with late-summer heat, mainly clear skies, and just a chance of scattered afternoon showers typical for the region. That’ll keep water clarity good and fish on the hunt near reef edges and flats. Fish activity’s been heating up. Snapper, especially yellowtail and mangrove, are showing in excellent numbers from Miami cut down to Islamorada. Local guides and Florida Insider Fishing Report note catches of respectable snapper up to 20 fish per boat, with legal mangrove and flag yellowtail mixed in. Plenty of lane snapper, grunt, and the occasional mutton reported out deeper. Inshore along Biscayne Bay, snook are busting mullet at dawn on the incoming tide. Tarpon continue to roll near bridges at first light, with a few fish breaking the 80-pound mark. Bonefish action remains steady off Miami Beach and Upper Keys flats, mostly in the 2–5 pound range, best in early morning before the sun gets high. Out in the bluewater, dolphin (mahi-mahi) are moving just past the reef line; yesterday, a handful of boats landed 6–10 fish apiece in the 8–12 pound class, mostly on trolled ballyhoo or skirts. Permit are cruising wrecks between Key Largo and Duck Key, with some hefty fish reported—bring crabs if you’re targeting these brutes. Hot lures and bait? For yellowtail, chum heavy and use small live pilchards or silversides. Locals swear by 1/16 oz pink or chartreuse jigheads tipped with shrimp for snapper—especially when the current runs hard at peak tides. Snook are hitting white paddle-tail soft plastics, DOA Baitbusters, and live mullet. For bonefish, the go-to remains live shrimp or pink ‘Gotcha’ jigs fished slow on the edge of the flats. Offshore, skirted ballyhoo or pink-and-blue trolling lures are nailing mahi; if you’re after blackfin tuna near the humps, try dark feathers and vertical jigs. A couple of proven hot spots: - Government Cut and Haulover Inlet in Miami for snook and tarpon on the morning flood tide. - The bridges near Islamorada, especially Channel 5 and Long Key, are producing good snapper, sea trout, This content was created in partnership and with the help of Artificial Intelligence AI.
