This South Padre Island fishing report covers early September, when the island is hot, still and full of fish and the fall pattern arrives ahead of the first front. Speckled trout on the Lower Laguna Madre flats are the lead target in the first two hours of light, and the midday heat is the condition to plan around. Redfish tail on the shallows, the jetties at Brazos Santiago Pass hold tarpon and snook on the outgoing tide, and the first bull reds of the fall run show along the beach and at the pass.
What’s Hitting
Speckled trout work the grass flats and spoil islands of the Lower Laguna Madre at first light, with some solid fish among them. Redfish tail on the shallow flats on the east side and on the sand along the island, and the first bull reds show at the jetties and in the surf.
Tarpon roll outside the jetties and along the beachfront, and snook sit on the jetty rocks on the outgoing and in the Brownsville Ship Channel at night. Flounder start to show around the jetties and the causeway, and kings and Spanish work the nearshore structure.
Where to Find Them
Look for trout on the grass flats between the Arroyo Colorado and the causeway, and around the spoil islands along the Intracoastal. Find reds on the east-side sand and the flats north of the causeway.
Fish the south jetty at Isla Blanca Park and the north jetty at Boca Chica for tarpon and snook. Flounder hug the jetty rocks and the Queen Isabella Causeway pilings, and kings hang on the nearshore wrecks and bait schools in 30 to 60 feet.
Tides & Conditions
Expect flats water in the upper 80s, with the bite fading once the sun is high. Be on the water at first light and fish wind-blown shorelines with a bit of chop. Outgoing tides are the jetty tides for tarpon and snook, and the wind usually builds in the afternoon.
Watch the tropical outlook closely, since the lower Texas coast is in play throughout September.
Tackle & Tactics
- Trout: a topwater at dawn, then a soft plastic on a light jig head once the sun is up.
- Reds: a gold spoon, a weedless soft plastic, or a live shrimp under a cork.
- Tarpon: a live mullet on a 7/0 circle hook and 80-pound leader.
- Snook: a live mullet or a swimbait on 40-pound.
- Bull reds: cut mullet or a live crab on a fish-finder rig.
- Flounder: a Gulp on a jig head.
Local Intel This Week
The Isla Blanca Park ramp is the closest launch to the south jetty and Brazos Santiago Pass. The Jim’s Pier area ramp on South Padre opens the bay side of the island, and the Port Isabel city ramp sits near the causeway flats. For the trout flats near the Arroyo Colorado, launch at the Adolph Thomae Jr. County Park ramp.
Plan the flats for first light and the jetties for the outgoing tide. Texas red drum and snook both carry specific rules, including an oversize tag requirement for reds. Check current state and federal regulations and seasons before keeping fish.
This Week’s Tip
Trout on the Laguna Madre flats in September push to the deeper edges of the grass by mid-morning. When the topwater bite dies, do not leave: move to the 3- to 4-foot edges and switch to a soft plastic worked slow.
