Ask any Galveston local when the best fishing of the year happens and you will hear the same answer: fall, when the flounder run. Every October, as the first cold fronts push across the Texas coast and bay waters start to cool, southern flounder leave the marshes and back bays and start moving toward the Gulf to spawn. They funnel through the same passes, channels, and jetties every year, which means anglers who know where to stand can have some of the most productive days on the water they will see all year.
For visiting families and fishing groups, the fall flounder run is one of the best reasons to book an October trip to the Island. The summer crowds are gone, the weather is comfortable, and you can fish from a pier, a jetty, a kayak, or the beach without needing a boat. This guide covers how the run works, where to fish around Galveston, what to throw, and the Texas regulations that change on November 1, plus a few BeachBox homes that make an easy base for an early morning bite.
What Is the Fall Flounder Run
Southern flounder spend spring and summer feeding in the shallow bays, marshes, and bayous around Galveston Bay. When water temperatures drop in the fall, usually starting in October and peaking into November, adult flounder migrate out through the passes and into the Gulf of Mexico to spawn offshore. Anglers call this seasonal migration the flounder run.
The key trigger is weather. A strong north wind and a falling tide after a cold front pushes bait and flounder toward the passes, and the days right after a front are often the best of the season. Flounder are ambush predators that lie flat on the bottom and wait for bait to come to them, so during the run they stack up along drop-offs, channel edges, and structure where the current carries shrimp and mullet past them.
Texas Flounder Rules for 2026
Before you plan your dates, know that Texas Parks and Wildlife Department rules make the timing of your trip matter. Under the 2026 to 2027 Outdoor Annual:
- Daily bag limit: 5 flounder per person
- Minimum length: 15 inches, with no maximum
- Possession limit: Equal to the daily bag
- Fall closure: November 1 through December 14, the flounder fishery is closed and the bag limit is zero. Any flounder caught during this window must be released.
- License: All anglers need a Texas fishing license with a saltwater endorsement
The closure protects flounder during the peak of their spawning migration, so October is the sweet spot for anglers who want to keep fish for dinner. If you visit in November, you can still fish and enjoy the catch-and-release action, but every flounder goes back in the water. Always check the current TPWD flounder regulations before you go.
Best Places to Catch Flounder in Galveston
The best flounder spots around Galveston share one thing: moving water that connects the bay to the Gulf. These are the areas we recommend first for visiting anglers.
San Luis Pass
At the far west end of Galveston Island, San Luis Pass connects West Bay and Christmas Bay with the Gulf, which makes it one of the most famous flounder funnels on the upper Texas coast. Anglers wade the edges and fish the shoreline drop-offs on outgoing tides, especially after a front. Fish here from shore or the bank only. The currents in the pass are extremely strong, and swimming and deep wading are dangerous.
- Best for: Experienced anglers and wade fishermen
- Location: West end of Galveston Island, where FM 3005 meets the San Luis Pass Bridge
- Insider tip: Fish the shallow edges near the drop-off rather than chasing deep water. Flounder sit right where the sand slopes into the channel. Parts of the beach here are soft sand, so a 4×4 helps if you plan to drive out.
Galveston Jetties
The granite jetties at the east end of the Island guard the entrance to the Houston Ship Channel and Bolivar Roads, the main highway for flounder heading out of Galveston Bay. The rocks hold bait, the current is steady, and flounder hug the base of the structure during the run. The South Jetty stretches out from the tip of East Beach.
- Best for: Anglers comfortable walking and fishing from rocks
- Location: East end of Galveston Island, past East Beach
- Insider tip: Wear shoes with good grip. The rocks are slippery, especially early in the morning.
Seawolf Park
On Pelican Island, just across the channel from downtown Galveston, Seawolf Park offers a fishing pier and rock shoreline right on the ship channel, along with a historic submarine and destroyer escort to explore. It is one of the easiest places for families to fish the flounder run without a boat.
- Best for: Families and casual anglers
- Address: 100 Seawolf Park Blvd, Galveston, TX 77550
- Phone: (409) 797-5114
- Insider tip: Combine a morning of fishing with a tour of the historic ships so non-anglers in your group have something to do.
Galveston Island State Park
The bay side of Galveston Island State Park features marshes, back lakes, and shallow flats that hold flounder all fall. It is a favorite for kayak anglers, with paddling trails that lead into quieter water away from the crowds at the passes.
- Best for: Kayak fishing and quiet wade fishing
- Address: 14901 FM 3005, Galveston, TX 77554
- Phone: (409) 737-1222
- Insider tip: Fish the mouths of marsh drains on a falling tide, when bait gets flushed out to waiting flounder.
How to Catch Flounder During the Run
Flounder fishing is all about slowing down. These fish wait on the bottom for bait to come to them, so the goal is to keep your presentation low and moving slowly with the current.
Live bait. Live mud minnows (also called mud fish or killifish), finger mullet, and live shrimp are the classic flounder baits. Fish them on a Carolina rig with a light sinker so the bait stays on the bottom and drifts naturally.
Artificial lures. Soft plastic paddle tails and shad-style baits on a jig head are local favorites. Bounce them slowly along the bottom and pause often. Many anglers tip their jigs with a small piece of shrimp or scented bait for extra appeal.
Setting the hook. Flounder often grab the bait and hold it before swallowing. When you feel a tap or a heavy weight, give it a few seconds before setting the hook firmly.
Gigging at night. Flounder gigging, wading the shallows at night with a bright light and a gig, is a Texas Gulf Coast tradition. It is legal during the open season but not allowed during the November 1 to December 14 closure, since no flounder may be kept. Book a local guide if it is your first time.
Hiring a guide. If you want to make the most of a short trip, a local Galveston fishing guide can put you on fish quickly and handle the gear and bait, which is a great option for families with kids.
When to Plan Your Galveston Fishing Trip
For the best chance at keeping fish, plan your trip for October, ideally timed around a cold front. Watch the forecast and aim to be on the water for the first two or three days after a front passes, when north winds and outgoing tides move flounder toward the passes.
A few tips that make fall fishing trips easier:
- Bring layers. October mornings on the Gulf can start cool and warm up quickly, and wind on the jetties makes it feel colder.
- Buy your license before you arrive. Texas fishing licenses with a saltwater endorsement are available online through TPWD.
- Check the tides. Outgoing tides are usually the most productive for flounder during the run.
- Book early. October weekends are popular on the Island, so lock in your rental before planning the rest of your trip.
