The Lower Laguna Madre is running its high-summer split shift: trout and reds on the grass at dawn, then tarpon, snook, and jetty fish once the boat traffic pushes everything off the flats. The tarpon showing at the jetties are the real headline — some of them are big.
What’s Hitting
This week, tarpon from 40 pounds to triple-digit class are rolling around the Brazos Santiago jetties and the channel edges on the early tides. Speckled trout are steady over the grass in 2 to 4 feet — solid keepers with a few big ones — and redfish are working the edge of the Intracoastal spoils and the sand pockets. Snook, the Texas kind, are holding in the Brownsville Ship Channel and around the jetty rocks, and the surf has whiting, pompano-size palometa, and sharks after dark.
Where to Find Them
Tarpon: the end of the jetties on the incoming at first light, and rolling fish along the channel. Trout: the grass flats west of the island, drifting with the breeze. Snook: dock lights in the channel at night and the jetty rocks on moving water.
Tides & Conditions
The building full moon strengthens the tidal exchange through Brazos Santiago Pass — that’s the trigger for the jetty tarpon and snook. Mornings have been light-wind with the standard afternoon southeast breeze filling in; flats water is hot and gin-clear.
Tackle & Tactics
Jetty tarpon: 60- to 80-pound leader, a swimbait or soft plastic eel swum through the rollers, or a live mullet drifted on the tide. Trout: soft plastics on 1/8-ounce heads over the grass, topwaters at gray light. Snook: white paddletails worked along the shadow lines at night, 40-pound leader against the rocks.
Local Intel This Week
Jim’s Pier and the Adolph Thomae Jr. County Park ramps cover the bay; the Isla Blanca Park jetty gives shore anglers a legitimate shot at the tarpon and snook. Fish are concentrating around the pass and jetties on the tides, and on the grass at dawn. Texas snook rules are strict and specific — check current TPWD regulations and seasons before keeping any fish.
Spots & Access This Week
The Port Isabel ramp and the South Padre Island convention center launch are the practical public access points, and Isla Blanca Park puts shore anglers directly on the Brazos Santiago jetty granite. Adolph Thomae Jr. County Park covers the Arroyo Colorado side for anglers working the deeper guts. Kayak anglers should stay on the spoil banks and protected flats north of the causeway, since the pass current is genuinely dangerous on a strong tide. Fish are concentrating at the jetties and the deeper guts rather than spread across the flats. Tarpon are catch-and-release under Texas rules without a specific tag — check current Texas Parks and Wildlife regulations before keeping any fish.
Timing the Tide at the Jetties
Everything at the jetties keys on the tide. On a strong outgoing, bait is flushed out of the pass and stacks in the rip beyond the last rock, and that is where the kings, tarpon and bull reds set up. Get up-current, cast past the rip line, and let the bait swing through it. On the flats, work the earliest light with topwaters and switch to soft plastics on a light jighead once the sun is up. The sea breeze is reliable and arrives by mid-morning, so build the day around being on the flats first and at the rocks afterward, where wind matters far less.
This Week’s Tip
Jetty tarpon here follow a rhythm — watch the rollers for a few minutes and time your cast so the bait swims into the pod as they cycle back up. Random casting puts fish down; a timed presentation gets an eat by the third cycle.
