Late July in the Keys means heat, flat mornings, and a rhythm that rewards anyone willing to leave the dock in the dark. The July 29 full moon just fired off the mutton snapper spawn on the patch reefs and humps, and the wreck permit bite is in its summer prime.
What’s Hitting
Permit are the standout — the ocean-side wrecks from Islamorada down through Marathon are holding good numbers of 20- to 30-pound fish. Mutton snapper are the other headline, with post-full-moon aggregations still working the deeper patches and reef edges in 60 to 90 feet. Yellowtail snapper are steady on the reef with a good chum slick. Mahi are scattered but present on the weedlines and frigate birds out past the 200-foot line. Tarpon numbers have thinned since June, but bridge fish are still around at night, and bonefish are on the ocean-side flats in the very early morning.
Where to Find Them
Wreck permit are hanging just off the structure rather than on it — look for them 50 to 100 feet up-current. Muttons are on the rubble edges adjacent to the patch reefs, not in the middle of them. Yellowtail come to the boat behind a steady chum line in 50 to 70 feet. Bonefish are working the ocean-side flats from Lower Matecumbe to Long Key on the early flood before the water heats. Bridge tarpon are on the Channel Two and Channel Five spans with strong current.
Tides & Conditions
Tides are running strong off the full moon and will moderate toward the weekend. Water clarity on the ocean side is very good, with light southeast wind most mornings and a building afternoon breeze. Water temps are 86 to 88 on the flats and low 80s on the reef. The bay side is very warm and very quiet in the middle of the day.
Tackle & Tactics
For wreck permit, a live crab on a 4/0 circle with 30-pound fluoro and just enough weight to hold — a jig-and-crab combo also works when the current picks up. Mutton snapper want a long fluorocarbon leader, 5 to 6 feet of 40-pound, and a whole ballyhoo or live pinfish fished on the bottom at first light. Yellowtail take a small hook, 15-pound fluoro, and a chunk of silversides drifted back in the slick. Mahi respond to a bucktail or live pilchard pitched at the weedline.
Local Intel This Week
Founders Park in Islamorada, the Marathon city ramp at 33rd Street, and the Murray E. Nelson ramp in Key Largo are the reliable public options. Fish are concentrating on the ocean side this week — the bay is hot and slow. Several species in the Keys carry seasonal closures and special Keys-only rules, so check current FWC regulations and seasons before keeping any fish.
This Week’s Tip
When you set up on a wreck for permit, anchor well up-current and let the crab drift back to the fish rather than dropping on top of them. Permit that see the boat first will not eat, and one blown drift can shut the wreck down for an hour.
