King mackerel season in Florida is open year-round in Gulf state waters, but that's not why our nearshore fishing charters get busy every fall. What changes is where the fish are. Kings spend summer scattered up the Gulf coast, then start sliding south as the water cools, and when that fall run reaches the structure nine miles off Anna Maria Island, the bite turns into some of the most consistent hookups of the year. If you're wondering when to book, watch the water temperature, not the calendar.

King Mackerel Season in Florida: The Current Rules

Gulf state waters allow king mackerel harvest year-round; there's no closed season to plan around. The bag limit is three fish per harvester, with a 24-inch fork-length minimum, and legal gear is limited to hook-and-line and spearing, per FWC's saltwater regulations. Rules can change season to season, so check the current numbers before you fish, especially if you're keeping fish rather than releasing them for the fight alone.

You don't need your own license to fish for them with us, either. FWC's charter licensing rules state that customers fishing under a boat's vessel license aren't required to hold an individual recreational saltwater fishing license — that's handled by the boat, not you.

Why the Fall Run Happens

Kings are a warm-water fish. NOAA Fisheries notes they generally avoid water colder than about 68°F and migrate north in summer, south in winter, as temperatures shift. Both the Gulf and South Atlantic stocks eventually converge in a wintering area south of the Florida Keys, between November and March. That southbound push is what puts more fish moving through our stretch of the Gulf coast starting in fall. It's not a hard start date on a calendar; it's a pattern tied to when the water off Tampa Bay and Anna Maria Island starts cooling, and it can run a few weeks early or late depending on the year. NOAA also notes the migration tracks changes in food availability as much as water temperature, so a cold snap isn't the only thing that can trigger it.

If you want to time a trip instead of guessing, NOAA's Tides and Currents site tracks real-time water temperature at Gulf coast stations. Watch for the first real drop off the local readings and you're watching the run start, not reading about it after the fact.

Other Species Moving Through the Same Water

King mackerel don't show up alone. The same nearshore structure that holds them this time of year also holds cobia, tripletail, sheepshead, and blacktip shark, plus the usual red drum and sea trout closer to the passes. That's part of why we run the nearshore trip the way we do: you're not booking a single-species chase, you're fishing water that's actively loaded up with options as fall sets in.

Fishing the Run on a Nearshore Charter

We run that trip out to roughly nine miles of Gulf structure from Holmes Beach, and king mackerel are one of the species we're targeting once the fall push gets underway. As the run builds each fall, that's exactly the water these fish move through on their way south. If you want to be on the boat when it happens, get a date on the calendar so you're out there while they're moving through, not reading about it afterward.

The trip runs as a four-hour, six-hour, or full-day charter, so there's a window that fits your schedule even if you're only in town for a weekend. Give us a call at 941-290-9187 or book online. We'll get you on the water while the fish are actually here.
