Why Fall Can Still Deliver Big Hits
When most anglers think of mahi-mahi — also known as dolphin or dorado — they picture the peak summer months in Key West. Warm water, long days, and steady east to southeast winds typically bring these fast-moving fish into our offshore range. But here’s a secret every seasoned captain knows: late-season mahi fishing can still be incredible if the conditions are right.
As we move into the fall, mahi don’t simply disappear. They follow structure, temperature, and current — and when South winds push warm blue water toward the Lower Keys, these neon-colored fish often stay within striking distance well past summer’s end. While the schools may be smaller and the fish more scattered, late-season mahi tend to be larger, more aggressive, and less pressured than they are during the busiest months.
For our charters, this time of year brings a special kind of excitement. Weedlines, floating debris, and bird activity are still prime indicators, and with fewer boats offshore, we can work these zones longer and more strategically. It’s not uncommon to hook into impressive bulls and cows even as we move deeper into fall.
There are many reasons Mahi are one of my customers’ favorite fish to catch. They are aggressive and fight very hard for their size. They can get very large. My personal “boat best” on the Southbound is 56lbs. and 68 inches long. The customer was only 64 inches tall. It was a hell of a good catch!!
Mahi are also a beautiful fish. When they come charging in, their colors are intense, and they are a sight to behold. Their peck fins glow iridescent blue in contrast to the blue-green and yellow of their bodies (the colors change)
One of the main reasons people like to catch Mahi is that they are a delicious fish. Unlike some fish, the larger Mahi taste just as good as the smaller ones, so no matter if you’re catching “chickens”,(small), “Schoolies” (medium), or “Slammers” big ones, Dinner will still be delicious.
If you’re looking for a light-tackle thrill, delicious fillets, and a chance to target one of Key West’s signature species without the summer crowds, late-season mahi fishing is absolutely worth it. With the right conditions — especially those favorable South winds — the bite can be just as memorable as midsummer.
