Chase Mahi in the Blue Water off the Florida Keys
Fast runs, bright colors, and offshore fishing that can go from quiet to wide open in a hurry.
Mahi mahi are one of the signature offshore fish we chase from Marathon. When the season and conditions line up, they're one of the most exciting fish you can target in the Florida Keys.
Mahi Mahi Fishing in Marathon: Quick Answer
Mahi mahi are an offshore, blue-water target around Marathon, with the general Florida Keys season running from April through October.
If mahi are the main reason you're coming to fish, give Captain Johnny a call before booking. He'll tell you what the bite has been doing and which trip makes the most sense.
Why Fish for Mahi from Marathon?
Marathon sits in the Middle Keys with access to reef, wreck, and offshore fishing.
For mahi, we're heading offshore and looking for the right water and signs of life.
Captain Johnny has spent more than 30 years fishing these waters. That local experience matters when the goal isn't simply reaching a spot on a map, but figuring out where the fish are that day.
What Is Mahi Fishing Like?
Mahi fishing is different from dropping baits over a reef or wreck.
We're covering offshore water and looking for the conditions and activity that can lead us to fish.
Once mahi show up, things can happen quickly.
They're fast, strong fish known for their green, blue, and yellow colors. For plenty of anglers, watching a mahi light up next to the boat is one of the highlights of fishing the Florida Keys.
When Is Mahi Mahi Season in Marathon?
The general Florida Keys mahi season runs from April through October, putting the heart of the action through spring, summer, and into fall.
That's a fishing calendar, not a guarantee.
Weather, water conditions, and the bite can change from one week to the next. If you're planning your whole trip around mahi, talk to Captain Johnny before you choose your charter.
How Long Should I Book for Mahi Fishing?
If mahi are your main target, give yourself enough time to fish offshore.
A Full Day Fishing trip gives Captain Johnny more time to cover water, work different areas, and adjust to what we're seeing.
For anglers looking for a bigger offshore day, our Big Game Offshore Adventure is built around making the longer run.
Depending on the trip and conditions, we also fish offshore grounds including the Humps, the Ups and Downs, and The Ledge
Can Beginners Fish for Mahi Mahi?
Absolutely.
You don't need years of offshore fishing experience to come chase mahi with us.
Captain Johnny and the crew can help with the equipment and show you what to do once the action starts.
Experienced anglers can get after it. First-timers can learn as they go.
What Else Can We Catch Offshore?
Mahi aren't the only reason we head into the blue water.
Depending on the season and conditions, Marathon's offshore fishing can also put us around species including wahoo, tuna, sailfish, marlin, and other pelagic fish.
That's part of the appeal of an offshore trip. We may leave the dock with a plan, but what's happening on the water ultimately helps determine how we fish.
