South Florida & Keys Offshore Fishing

South Florida and the Florida Keys form one of the most diverse and productive offshore fishing regions in the world. The proximity of the Gulf Stream to the coastline — often running within 15 miles off Palm Beach County and tightening to under 10 miles near Fort Lauderdale — gives anglers quick access to blue water and pelagic species that other regions can only dream of. From the deep reefs and wrecks off Miami to the backcountry flats and offshore humps of the Keys, this region offers something for every offshore angler year-round. Water temperatures rarely dip below the low 70s even in winter, keeping bait and gamefish active through every season.

The Gulf Stream dominates this region, flowing northward at 2-4 knots and carrying warm, nutrient-rich water from the Caribbean. Off Jupiter and Stuart, the Stream runs 15-20 miles offshore, but it pushes progressively closer as you move south, hugging the reef line off Fort Lauderdale and Miami. The western wall of the Stream creates temperature breaks and current edges that concentrate bait and predators. In the Keys, the interplay between Atlantic and Gulf of Mexico water masses generates unique eddies and current seams, particularly around the Islamorada Hump and Marathon's western ridges. The continental shelf drops steeply off the upper Keys, while the shelf broadens significantly west of Marathon.

Success in South Florida and the Keys hinges on reading the Gulf Stream's daily position and identifying productive temperature breaks. In winter, sailfish stack up along the Stream's western edge from Stuart to Miami, and the kite fishing fleet targets them on temperature differentials as small as one degree. Summer shifts the focus to mahi runs on weedlines and wahoo on deep trolling spreads. In the Keys, anglers work the humps and deep drops for swordfish and tilefish while running offshore for tuna. Monitoring SST charts for Stream meanders and cold-water upwellings is critical — a westward push of the Stream can turn a slow reef day into a pelagic bonanza within a few miles of shore.
