May 2025 Islamorada Fishing Report: Tarpon, Snapper & Mahi

‍Fishing in Islamorada is firing on all cylinders this May. Whether you're chasing the thrill of a tarpon fight or looking to load the cooler with snapper and mahi, now’s the time to hit the water in the Florida Keys.

‍

Tarpon Biting Strong in the Backcountry

Bridge fishing is slower this year, but the backcountry tarpon bite is on fire. Local captains report 6-10 bites per morning in the channels and basins north of Islamorada, especially on outgoing tides.

• Best bait: Live mullet or small crabs
• Gear: 30–50 lb setup with 60–80 lb leader and circle hook
• Top areas: Snake Creek and the Everglades backcountry channels
• Tip: Start early—sunrise is when the silver kings are most active

‍

Reef Fishing: Yellowtail & Mutton Snapper

The reef bite is red-hot in 60–90 ft of water. Yellowtail snapper are thick in the chum slick, and mutton snapper are lurking deeper.

• Best bait: Cut squid, ballyhoo, and live pilchards
• Tactics: Anchor, chum heavy, and drift bait back naturally
• Top spots: Alligator Reef, Pickles Reef, deeper wrecks for muttons
• Tip: Light line and fluorocarbon leader get more bites

‍

Offshore Mahi Starting to Show

Mahi-mahi are here, especially around floating debris and weed lines in 600–800 ft. Look for frigate birds and troll skirted ballyhoo.

• Baits/lures: Skirted ballyhoo, jet heads, live pilchards
• Top areas: Offshore of Alligator Reef and the Islamorada Hump
• Tip: Hook one, then stop and chunk to keep the school around
