Fishing Seasons in Key Largo – What’s Biting When

Fishing in Key Largo isn’t just a pastime—it’s a way of life. With warm waters, coral reefs, and access to both the Atlantic Ocean and the Florida Bay, the area offers world-class fishing twelve months a year. All Hanns On Deck Fishing Charters brings you the ultimate month-by-month guide to help you plan your trip around the best fishing seasons in Key Largo. Whether you’re chasing Mahi Mahi offshore, dropping baits for Snapper on the reefs, or battling Sailfish during winter, there’s always something biting.

January – March: Sailfish and Snapper Season

Winter brings calm, cool weather and clear blue water—ideal for Sailfish, Blackfin Tuna, and King Mackerel. Offshore currents push baitfish close to the reef, attracting pelagic predators. Reef anglers can expect solid action on Yellowtail and Mutton Snapper, while bottom fishing produces Grouper until the seasonal closure begins.

April – June: Mahi Mahi Madness

Spring and early summer are peak months for Mahi Mahi fishing in Key Largo. Floating weed lines and color changes offshore hold schools of brightly colored dolphin fish. You’ll also find Wahoo, Amberjack, and Blackfin Tuna around deeper wrecks. Closer to the reef, Mangrove Snapper and Barracuda start heating up. Now’s the best time to book a Key Largo offshore fishing trip if you want steady action and calm seas.

July – September: Night Fishing and Summer Snapper

Summer is prime time for Yellowtail Snapper, especially on evening and night reef trips. Warm, clear water and light winds make for comfortable fishing conditions. Captain Justin Hann of All Hanns On Deck offers flexible night charters perfect for families and small groups. While the surface slows during the heat of the day, nighttime brings the reef alive with Snapper, Sharks, and Barracuda.

October – December: Grouper, Tuna, and Fall Action

As temperatures cool, Grouper fishing in Key Largo picks up again, along with Blackfin Tuna offshore. The fall months offer a mix of reef and offshore opportunities, making it one of the best times for variety. Mahi remain possible into early fall, while Sailfish return as the water cools. Fall trips are a great option for anglers looking for fewer crowds and strong, consistent bites.
