Fish of the Florida Keys

The Florida Keys sit at the crossroads of the Atlantic and the Gulf, giving Marathon some of the most diverse fishing anywhere in the country. While there is something biting year round, knowing the best time to fish for each species helps you plan the perfect trip.

Use this seasonal guide to see what you can catch in Marathon each month, when each fish is in season, and the trips where you can target them.

Winter

Dec · Jan · Feb

Prime sailfish season in the Keys. Blackfin tuna and wahoo are active offshore, and the reefs keep producing snapper and grouper year round.

Spring

Mar · Apr · May

The best all around season to fish Marathon. Sailfish are still running, mahi arrive, cobia and mutton snapper show up, and tarpon fishing turns on.

Summer

Jun · Jul · Aug

Peak mahi season with loaded weedlines offshore. Tarpon fishing is at its best around the bridges, and the reefs stay busy with snapper.

Fall

Sep · Oct · Nov

Wahoo and kingfish pick up, sailfish start to move back in late fall, and mahi often hang around. A great time with fewer crowds.
