Tips & Techniques
- ✓The Florida Keys backcountry flats hold permit, bonefish, and tarpon — the Grand Slam of flats fishing — in sight-fishing conditions
- ✓Tarpon migrate through the Keys from April through July with fish averaging 80–150 pounds; the seven-mile stretch near Bahia Honda is legendary
- ✓Islamorada is known as the Sport Fishing Capital of the World — reef, wreck, and offshore fishing for mahi, tuna, and wahoo is excellent from March through October
- ✓Incoming tide activates permit and bonefish feeding on shallow flats — both species actively tail in water less than 2 feet deep
- ✓The Atlantic-side patch reefs from Key Largo to the Dry Tortugas hold yellowtail snapper, grouper, and cobia year-round
- ✓Full moon phases in May and June trigger the famous Palolo worm hatch at night — tarpon daisy chains feeding on the surface
- ✓Backcountry fishing in Florida Bay (Gulf side) targets redfish, snook, and seatrout on shallow grass flats protected from offshore swells
- ✓Light southeast wind (5–12 mph) creates ideal visibility for sight-fishing flats — strong or north winds push fish off the flats

How We Score Fishing Conditions
🌙 Lunar Phase
New and Full Moons produce peak fish activity (score: 2). First/Last Quarter and crescent phases produce moderate activity (score: 1–1.5).
💨 Barometric Pressure
Rising pressure (score: 2) strongly activates feeding. Stable pressure (score: 1) produces normal activity. Falling pressure (score: 0) suppresses the bite.
🌬️ Wind Speed
Light winds under 3 m/s (score: 2) are ideal. Moderate 3–8 m/s (score: 1). Strong winds above 8 m/s (score: 0.5–0) suppress feeding.
Frequently Asked Questions
Is a guide required to fish the Florida Keys flats?
Not legally required, but highly recommended. Permit and bonefish sight-fishing requires specialized knowledge of tides, flat locations, and presentation. A certified flats guide dramatically improves your chances on a first visit.
When is the best time to visit the Florida Keys for fishing?
March through July is the best window — spring tarpon migration, permit and bonefish in warm water, and offshore mahi season all peak simultaneously. Winter (December–February) is slower inshore but excellent for snapper and grouper on the reef.
What is the best bait for tarpon in the Florida Keys?
Live crabs are the top natural bait for Keys tarpon. Live mullet, pinfish, and threadfin herring also produce. Fly fishing with large EP flies, tarpon toads, and crab patterns is the preferred method for experienced anglers.
Can I catch permit in the Florida Keys without a guide?
It is extremely difficult. Permit are highly selective and require precise presentation to feeding fish spotted by sight. Most successful permit fishing is done with experienced guides who know where fish feed on each tide cycle.
Are there public access areas for fishing in the Florida Keys?
Yes. Long Key State Park, Bahia Honda State Park, and the Seven Mile Bridge all provide public access to productive fishing. These areas are excellent for families targeting snapper, jack, and small tarpon from shore.
