March and April are great months for fishing in the Keys, and of course Key West has plenty of other entertainment options.
Offshore, the mahi bite should be going strong, blackfin tuna are available in good numbers, and there are plenty of sailfish still in the area. You might even get lucky and land a marlin. The experts have been catching more of them in recent years.
On the reef, you’ll catch plenty of yellowtail snapper, mangrove snapper and myriad grunts. By April the mutton snapper bite turns on.
On the flats, it’s prime time for permit and bonefish. The tarpon migration will begin moving through in late March. And there are plenty of cobia on the shallow wrecks. If you’re into sight fishing with fly and/or light tackle, Key West is hard to beat.
Diving is also a go. Check out the coral reefs or dive the wrecks. You’re sure to see some big fish on those things.
