Fly Fishing the Florida Keys & Everglades in March

March marks the true shift from winter to spring in the Florida Keys and Everglades. While occasional cold fronts still push down from the north, they are weaker, shorter, and less frequent than earlier in the year. Longer warming trends dominate, with stable conditions that last for days at a time. Water temperatures rise steadily into the mid to upper 70s, creating ideal conditions for tarpon, permit, and bonefish. These more prolonged windows of good weather give anglers greater consistency and more opportunities to sight fish across the flats, channels, and backcountry. Even when the winds pick up, protected areas in the Everglades or the leeward sides of the Keys provide fishable water.
