August 2026 Fishing Report — Marathon, Florida Keys

August keeps two fisheries going at once out of Marathon. The reef is holding steady for snapper, and the blue water offshore is still producing on the mahi mahi run. It is exactly the kind of month that makes a family trip out of Marathon worth planning around.

Mahi Mahi

Mahi mahi continue to show in the blue water off Marathon through the back half of summer. August is a solid window for anglers hoping to put a mahi in the box, and it is one of the most exciting fish out there for anglers of any experience level.

They hit hard, they jump, and they show up in every color of the rainbow, which makes them a favorite for families and first time anglers who want a fish that puts on a show.

Yellowtail Snapper & Mangrove Snapper

On the reef, yellowtail snapper and mangrove snapper are keeping rods bent all summer long. Both species are reliable staples of a Marathon reef trip and make for great table fare.

Reef and wreck trips out of Marathon offer a good mix of species and a manageable pace, which is part of what makes them such a good fit for families and anglers of all experience levels.
