Your species-by-species guide to fishing the Middle Keys with Sweet E’Nuf Charters
Every angler headed to the Keys asks the same question first: “So… what’s biting?” Late summer in Marathon has one of the best answers of the whole year — because the honest answer is: almost everything. Here’s the species-by-species scoreboard for August and September in the Middle Keys, so you can pick your fight before you ever step on the boat.
MAHI-MAHI (Dorado) — PEAK SEASON
- Where: Offshore, along weed lines, current edges, and floating debris.
- The draw: Summer is prime mahi time in the Keys. They travel in schools, hit hard, jump wild, and light up in electric green and gold. When the bite is on, everyone on the boat is hooked up at once.
- On the table: One of the best-eating fish in the ocean — mild, sweet, and perfect grilled or blackened.
- Book-it tip: Mahi is an offshore run — a full-day trip gives you the time to find the fish and fill the box.
TARPON — STRONG SUMMER BITE
- Where: The bridges and channels around Marathon — some of the most famous tarpon water in the world, right beside the Seven Mile Bridge.
- The draw: They call it the Silver King for a reason. Tarpon run well over 100 pounds, leap completely out of the water, and will test every ounce of your arms. Tide changes and early mornings are prime.
- On the table: Tarpon are a catch-and-release fishery in Florida — this one’s all about the fight and the photo.
- Book-it tip: Ask about morning trips timed to the tide.
BLACKFIN TUNA — STEADY
- Where: The offshore humps — underwater seamounts near Marathon that stack up bait and tuna.
- The draw: Pound for pound one of the hardest-pulling fish you’ll hook in the Keys. Expect burning runs and a real workout.
- On the table: Outstanding — blackfin sashimi and seared tuna don’t get any fresher than same-day.
- Book-it tip: Pairs well with a mahi trip — both live offshore.
YELLOWTAIL & MANGROVE SNAPPER — RELIABLE YEAR-ROUND
- Where: The reef and wrecks, just a short run from the dock.
- The draw: The Keys’ most dependable action — snapper bite virtually every day of the year. Steady rod-bending fun that keeps kids and first-timers busy all trip.
- On the table: A Keys classic. Light, flaky, and a favorite at local restaurants.
- Book-it tip: The go-to family trip — a half day on the reef is plenty.
WAHOO — BUILDING INTO FALL
- Where: Offshore — the bite typically builds as the Keys ease from summer into fall.
- The draw: One of the fastest fish in the sea, with strikes that scream drag off the reel. Fall is when Keys anglers start counting the days.
- On the table: Firm, white, and delicious — ‘ono’ means ‘delicious’ in Hawaiian for a reason.
- Book-it tip: Fall wahoo dates are popular — booking ahead is smart.
Quick-Fire Round: Your Most-Asked Questions
Do I need experience? None. Charter trips include the rods, tackle, and know-how — you bring sunscreen, drinks, snacks, and polarized sunglasses.
Do I need a fishing license? No — anglers on a licensed Florida charter boat are covered by the boat’s license.
Can we eat what we catch? Yes — legal catch can be cleaned after the trip, and several Marathon restaurants offer to cook your catch. Dinner doesn’t get fresher.
Half day or full day? Half days are great for the reef and tarpon. If mahi, tuna, or wahoo are calling, book the full day so there’s time to run offshore.
