Port Isabel, TX Fishing Guide
Port Isabel sits at the southern tip of Texas, where the Lower Laguna Madre and the Gulf of Mexico meet. Most local trips are either half-day inshore runs for trout and redfish, or full-day ventures that push through Brazos Santiago Pass into bluewater for kingfish, snapper, and mahi in season. Inshore charters work the grassy flats, sand pockets, and channels of the Laguna Madre, as well as the jetties at South Padre Island. This fishery is shallow and clear, with sight-casting possible much of the year. Skiffs and bay boats dominate the inshore scene, able to run skinny water just inches deep.
Offshore runs leave from the Port Isabel side of the pass, with most prime reefs and rigs sitting 10–40 miles out. Summer sees captains chasing mahi and sailfish farther offshore, while winter trips target red snapper on nearshore structure. Launch points include the Port Isabel Public Boat Ramp and ramps along the Intracoastal Waterway. Most inshore trips stay within 5–15 minutes of the dock, while offshore boats can run an hour or more to reach target grounds.
Seasonally, spring brings schooling trout on the flats and sheepshead around structure. Summer’s heat pushes speckled trout deeper in the channels during the day, with early mornings and evenings best for topwater action. Fall offers aggressive redfish feeding on bait migrations, while winter means slower, deeper fishing with soft plastics and live bait. Common techniques inshore include drift fishing with live shrimp under popping corks, sight-casting soft plastics, wading with artificials, and slow-rolling jigs. Offshore captains troll, bottom fish, and sometimes kite fish for pelagics.
Nearby options include running north toward Port Mansfield for remote flats, or south into Mexican waters with proper permits. Whether wading the grass edges or running out past the rigs, Port Isabel offers year-round fishing for anglers who know how to work the tides, winds, and seasonal changes.
Fishing Seasons in Port Isabel
Spring (March–May)
Spring fishing in Port Isabel starts with warming flats and increased bait movement. Speckled trout school up on shallow grass and sand edges, and redfish start cruising shorelines in singles and small pods. Sheepshead are thick around pilings and jetties early in the season. Half-day bay trips are popular as weather can shift quickly. Live shrimp under popping corks and soft plastics worked over potholes produce well. Winds can still be strong, so captains often fish leeward shorelines. Offshore, kingfish begin showing nearshore, and snapper action improves on reefs.
Summer (June–August)
Summer brings some of the most consistent fishing of the year in Port Isabel. Trout feed early and late on topwaters and soft plastics before dropping to deeper channels mid-day. Redfish school along spoil islands and back bay cuts. Offshore trips peak for mahi, sailfish, and kingfish, with boats running 20–40 miles out. Many captains start trips at dawn to beat the heat, and night fishing around the causeway lights is popular for trout and mangrove snapper. Live bait—croaker, piggy perch, or mullet—is in high demand for trophy trout.
Fall (September–November)
Fall fishing means bait runs along the jetties and shoreline, and redfish feed aggressively ahead of winter. Schools of slot and bull reds push into the surf and passes. Trout move back onto the flats with cooler water, and flounder stage near channels ahead of their migration. Offshore, kingfish remain steady, and wahoo can be targeted on longer runs. Charter demand is steady, with anglers favoring full-day trips to take advantage of mild weather and active fish. Jigging spoons, soft plastics, and cut bait all work well.
Winter (December–February)
Winter in Port Isabel can still produce excellent fishing, especially on warmer days between fronts. Trout hold in deeper holes and channels, with soft plastics and slow presentations key. Redfish stay active in shallow mud flats on sunny afternoons. Offshore trips target snapper, grouper, and amberjack when seas allow. Half-day bay trips are common due to shorter daylight and cooler temperatures. Live shrimp and slow jigging over structure are reliable methods. Wading anglers often focus on midday windows when the water warms slightly.
