May 2025 — South Padre Island: Pre-spawn redfish, offshore snapper season approaching. May is a late spring month with water in the 74-80°F range — tarpon arriving Gulf passes; offshore action builds. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics.
What’s Biting — May 2025
Primary targets this month: Speckled Trout, Redfish, Tarpon, Snook.
Speckled Trout
Summer trout in the Lower Laguna Madre (some of the best trout fishing in Texas), Baffin Bay (just north), the Land Cut, Mexiquita Flats, and the spoil islands — focus on deeper grass edges and potholes early and late. Live shrimp and pinfish under popping corks; trolling MirrOlures over grass flats.
Redfish
Summer redfish in the Lower Laguna Madre flats, the Land Cut, the Arroyo Colorado, Cullen’s Bay, the South Bay, and the shorelines of Padre Island National Seashore. Fish dawn and dusk — once water hits 85°F bites slow significantly. Live pinfish, cut ladyfish, topwater walking baits at first light.
Tarpon
Peak tarpon season. Fish stacked on the Brazos Santiago Pass, the Gulf side of South Padre, the offshore beach in summer — the Texas tarpon recovery is centered here. Live crabs, threadfin herring, pinfish on 6/0-8/0 circle hooks and 60-80 lb fluoro leader. Pre-dawn anchor bites at major passes; sight-fishing the beach; rolling fish in the channels.
Snook
Snook season is closed for harvest in Florida — catch-and-release only this month. Target the Brownsville/Port Isabel area, the Brazos Santiago Pass jetties, the South Bay, and the Lower Laguna Madre — Texas’s strongest snook population for fun. Handle fish carefully and release quickly.
Water Conditions & Patterns
Water temperatures are running 74-80°F. Tarpon arriving gulf passes; offshore action builds. South Padre tides are minimal (typically 1 foot or less) — wind dominates the Lower Laguna Madre. South winds push water in and concentrate bait on the windward flats; north winds drop water and concentrate fish in the deeper holes. The Brazos Santiago Pass moves real tidal current and fishes best on outgoing tide.
Check the NOAA marine forecast and tide charts before launching. Wind direction often matters more than wind speed for inshore fishing — clean water beats churned water nine times out of ten.
Tactics & Tackle for This Month
- Early and late. 5-9 AM window and 6 PM to dark are gold; midday water temps push fish deep or into shade.
- Live bait season. Cast-net pilchards, scaled sardines, and threadfins for snook, tarpon, and snapper. Chum with a few live ones to start a feed.
- Storm awareness. Afternoon thunderstorms develop fast — check radar before and during trips. Get off at first thunder.
May Outlook
Late spring — tarpon arriving, snook moving, summer pelagic season building offshore.
