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
