Florida Fall 2026 Fishing Season Openers: Snook, Gag Grouper and What Changed

Gag grouper reopened in Gulf state waters on September 1 for one month only: it closes again October 1 and stays closed for the rest of the year. Snook is the opposite story in Southwest Florida. Most of the Gulf coast reopened to snook harvest on September 1, but FWC keeps the Charlotte Harbor and Southwest regions, which cover Lee, Collier and Charlotte counties, closed through September 30. Here, snook harvest reopens October 1, the same day gag closes.

Snook: closed here until October 1, then open through November

Snook harvest in the Gulf-side Charlotte Harbor and Southwest regions, which cover Lee, Collier and Charlotte counties, closed May 1 and stays closed through September 30, 2026. FWC lists these two regions with a longer summer closure than the rest of the Gulf, which reopened September 1. Harvest here reopens October 1 and runs through November 30, before the winter closure starts back up December 1 and runs through the end of February. Until October 1, snook in Lee, Collier and Charlotte are catch and release only. The slot stays the same year round: not less than 28 inches or more than 33 inches total length, one fish per person per day, and a snook permit required on top of the base saltwater license. Fall is one of the better stretches of the year for snook here, with fish dropping back out of the passes and beaches into the backcountry as water cools. See our snook species guide for where and how to fish this window, and our season calendar for the exact closed dates going forward.

Gag grouper: a one-month window, then closed again

This is the one worth double-checking before you book a trip. Gulf state-water gag grouper is open September 1 through September 30, 2026, and FWC’s own language is direct about what happens next: harvest closes October 1 for the remainder of the year. That’s a change from the longer open stretch anglers may be used to in other years, and it means a trip planned for October assuming gag season is still running would come up against a fish that has to go back regardless of size. The minimum size is 24 inches total length, with up to 2 gag counted within a 4-grouper aggregate bag limit per person per day. Charter captains and crew carry a zero-fish bag limit on grouper. Red grouper and black grouper, by contrast, are open year round in Gulf state waters at 20 and 24 inches respectively, so a trip that misses the gag window can still target those instead. Our gag grouper guide and our roundup of every grouper species and how to tell them apart cover tackle and identification for the wider structure bite.

Redfish: no change, still open

Redfish don’t have a seasonal opener to track. Harvest stays open year round in the Southwest and Charlotte Harbor regions, with an 18 to 27 inch slot, one fish per person per day and a two-fish vessel limit. Fall is genuinely one of the best stretches for redfish here regardless of the calendar quirks affecting snook and grouper: bigger fish school up on the flats and oyster bars as water stays warm through October and November. If a grouper trip gets rained out or the offshore window closes, redfish on the flats is the reliable fallback, and it’s catchable from shore.

Why this matters more than usual this fall

Gag grouper opening September 1 makes it easy to assume Southwest Florida snook opened with it, since the rest of the Gulf did. It did not. Snook in Lee, Collier and Charlotte opens October 1 and stays open through the end of November; gag closes on that same October 1 after a 30-day window. A boat rigged for an offshore grouper trip in the second week of October is targeting a species that’s currently closed, even though the season “just reopened” a few weeks earlier in most anglers’ memory. Checking the actual current status before each trip, rather than working off what was true last month, is the only way to avoid that mismatch. FWC’s own Fish Rules app and the source pages linked throughout this post are the fastest way to confirm status the morning of a trip.

Before you go

Regulations here move fast enough that a page written even a few weeks ago can be out of date on a specific closure. Our regulations page tracks the current figures for every species covered on this site, each one linked to the FWC page it came from, and the season and regulation calendar is built specifically around Southwest Florida’s Gulf-side rules. Make sure your fishing license is current before you head out, whichever species you’re chasing this fall.
