King mackerel landed near a Gulf coast jetty — illustrative photo

This week on South Padre the Brazos Santiago jetties are carrying the report. Late August puts green Gulf water right against the rock on calm mornings, and with it come kingfish, tarpon and everything else with a fin. Inside, the Laguna Madre is hot and clear, which makes the flats fishing a dawn proposition — but a very good one for anglers who beat the sun.

What’s Hitting

Kingfish are the most dependable jetty and nearshore target, with Spanish mackerel mixed in and the occasional cobia. Tarpon are rolling at the jetties and along the beachfront on flat mornings — this is the peak of the local season. Speckled trout are on the Laguna Madre grass flats and the deeper guts at first light. Redfish are on the spoil edges and the sand pockets, with tailing fish on the calmest mornings. Snook are around the jetty rock and the Brownsville Ship Channel structure. Flounder are showing on the sandy drops.

Where to Find Them

Work the Brazos Santiago jetties and the beachfront just north and south for kings and tarpon on a calm, green-water morning. 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. Nearshore rigs and hard bottom in 40 to 80 feet hold kings and bottom fish.

Tides & Conditions

Tidal range is small on the lower Texas coast and largely wind-driven — this week’s light morning wind should push clean green water to the beach and the jetty, which is exactly the setup you want. Water is 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.

Tackle & Tactics

For 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. Tarpon at the jetty want 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. On the flats, a 2500-size spinner with 10- to 15-pound braid, 20-pound fluoro, and 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, and 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 are concentrating on the green-water line at the jetty and on the grass-and-pothole edges inside — not on featureless flats. Texas trout, redfish and flounder limits were revised in recent seasons and differ from neighboring Gulf states; check current Texas Parks and Wildlife regulations before keeping any 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 up-wind side and let your plastic fall into the hole — most eats come as it drops off the grass edge.
