This South Padre Island fishing report covers late August, when the Brazos Santiago jetties carry the report. Calm mornings put green Gulf water right against the rock, and with it come kingfish, tarpon and everything else with a fin. Inside, the Laguna Madre runs hot and clear, which makes the flats a dawn proposition, but a very good one for anglers who beat the sun. Plan around the southeast sea breeze, which fills by mid-morning and keeps the fishable window short.
What’s Hitting
Kingfish are the most dependable jetty and nearshore target, with Spanish mackerel mixed in and the occasional cobia. Tarpon roll at the jetties and along the beachfront on flat mornings; late August is the peak of the local season.
Speckled trout are on the Laguna Madre grass flats and the deeper guts at first light. Redfish work the spoil edges and the sand pockets, with tailing fish on the calmest mornings. Snook hang around the jetty rock and the Brownsville Ship Channel structure, and flounder show on the sandy drops.
Where to Find Them
On a calm, green-water morning, work the Brazos Santiago jetties and the beachfront just north and south for kings and tarpon. Nearshore rigs and hard bottom in 40 to 80 feet hold kings and bottom fish.
The Laguna Madre grass flats from the Convention Centre flats north toward the Land Cut hold trout and redfish; look for potholes and grass edges. The spoil islands along the Intracoastal are reliable redfish structure through the middle of the tide.
Tides & Conditions
Tidal range is small on the lower Texas coast and largely wind-driven. A light morning wind pushes clean green water to the beach and the jetty, which is exactly the setup you want. Water runs 86 to 90 degrees.
The southeast sea breeze fills by mid-morning and gets strong by afternoon, so the fishable window is genuinely short. Scattered afternoon storms are possible, so keep an eye on the radar.
Tackle & Tactics
- Kings: slow-troll a live mullet or ribbonfish on a light-wire stinger rig, or throw a heavy casting metal at bait pods along the rock. The stinger matters because kings often slash at the tail of a bait.
- Jetty tarpon: a 6000- to 8000-size spinner, 50- to 65-pound braid, 80-pound fluorocarbon and a big swimbait or a live mullet cast well ahead of rolling fish.
- Flats: a 2500-size spinner with 10- to 15-pound braid and 20-pound fluoro, with a soft plastic on a light head, or a topwater at first light.
Wade rather than drift when the water is glass.
Local Intel This Week
The South Padre Island Convention Centre ramp and the Port Isabel public ramp are the standard launches. The Adolph Thomae Jr. County Park ramp gives access to the Arroyo Colorado. Shore anglers do well from the jetty granite on the island side and from the Isla Blanca Park shoreline.
Fish concentrate on that green-water line at the jetty and on the grass-and-pothole edges inside, not on featureless flats. Texas trout, redfish and flounder rules differ from neighboring Gulf states. Check current state and federal regulations and seasons before keeping fish.
This Week’s Tip
On the Laguna flats in this heat, fish the potholes on the edge of the grass rather than the open sand. A pothole is cooler, holds bait, and gives a trout an ambush point with cover on three sides. Work the upwind side and let your plastic fall into the hole; most eats come as it drops off the grass edge.
