Keys Flats Fishing Report: Tarpon, Bonefish, and More Bite in Late Summer Bounty

Good morning from the Florida Keys—Artificial Lure here with your updated fishing report for Wednesday, August 20, 2025. Sunrise brought color to the flats at 7:03 AM with sunset expected at 7:56 PM, giving us nearly 13 hours of sunlight to chase fish across gin-clear waters. The weather’s doing us a favor today: winds are light, skies mostly clear, and that classic late-summer humidity’s holding steady, which means plenty of fish activity according to the local guides on Keys Flats Fishing Charters. Tide action is strong, with a high tidal coefficient today at 88 and rising, so you’ll see good water movement. The morning high in Key West hits at 8:13 AM and drops to near dead low by 3:03 PM—a prime window for feeding activity around the edges and channels, especially with the increasing current through the backcountry, reefs, and bridge pilings, as shared on Tide-Forecast.com. Out on the flats, anglers are still raving about tailing bonefish and some solid shots at permit during the higher stages of the tide. Key West Flats Fishing Charters reports tarpon are cruising channels at first light, often feeding aggressively around the incoming tide. The shallow waters between the islands are loaded with juvenile tarpon and barracuda, which are both entertaining and ready to smash twitch baits or fly presentations. For reef action, expect strong bites from snapper and grouper around midday when that water drops out. Yellowtail snapper have been thick along the outer patches—live pilchards and fresh cut ballyhoo are consistently putting fish in the box. Those targeting mutton snapper have also had success bumping the bottom with jigs just offshore, per recent local charter logs. As for lures and bait, tackle shops like Discount Tackle and the locals are moving a lot of Z-Man soft plastics, Rapala X-Raps, and bucktail jigs for inshore and bridge fishing. Topwater poppers and shrimp-imitating soft baits are excellent at dawn or dusk for snook and sea trout around mangrove edges. For hardcore flats folks, nothing beats live shrimp or small blue crabs when sight-casting at permit and bones, while silver or chartreuse artificial lures still fool plenty during moving water. Offshore, trolling Nomad Design, Nomad Madmacs, or traditional feathered jigs around humps is getting dolphin (mahi) and blackfin tuna. Notable hotspots this week include: - Western Sambo Reef: strong snapper, grouper, and even occasional cobia showing up, especially on the falling tide. - Sugarloaf Key backcountry: reliable shots at tarpon and bigger jacks at first light. - Vaca Cut and Long Key bridges: tide-swept pilings are loaded with mangrove snapper and the odd snook at sunrise. The lighter crowds this time of year offer prime water—more fish, less boat pressure, and plenty of room to drift or stalk quietly. Local guides remind everyone to keep it simple: stick to the tides, fish the moving water, and don’t overthink your lure selection.
