March 2026 — South Padre Island: Spring redfish and trout on warming flats, cobia building. March is a early spring month with water in the 62-70°F range — COBIA peak migration; trout and redfish transitioning to flats. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics.
What’s Biting — March 2026
Primary targets this month: Redfish, Speckled Trout, Snook, Black Drum.
Redfish
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. Cut bait, gold spoons, and soft plastics on light jigheads.
Speckled Trout
Trout holding 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. Live shrimp under a popping cork, soft plastic jigs in natural colors (root beer, new penny, opening night).
Snook
Snook in the Brownsville/Port Isabel area, the Brazos Santiago Pass jetties, the South Bay, and the Lower Laguna Madre — Texas’s strongest snook population. Live pilchards, scaled sardines, finger mullet. Artificial: white DOA Bait Buster, MirrOdine, walking topwaters at first and last light. Always verify current FWC snook season — slot is 28-33″ with seasonal closures.
Black Drum
Black drum (bull drum 30+ lb) on the channels, the Brazos Santiago Pass, the Arroyo Colorado, and the surf during the spring run. Cut blue crab, fresh shrimp, or peeler crab on a 5/0-7/0 circle hook with enough weight to hold bottom. Slow, deliberate fishery — set the rod and wait for the rod to bend.
Water Conditions & Patterns
Water temperatures are running 62-70°F. Cobia peak migration; trout and redfish transitioning to flats. 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
- Cobia readiness. Keep a heavy spinning rod (8000-class, 40-50 lb braid, 60-80 lb fluoro) ready with a bucktail or live eel — cobia don’t announce themselves.
- Sight-fishing weather. Plan trips around calm seas and sun overhead. Polarized lenses essential.
- Bait migration. Spanish, kings, and predators follow bait pods — watch for diving birds and surface activity.
March Outlook
Spring transitions accelerate — water warming, fish moving onto flats, migrations intensifying.
Regulations Reminder
Snook: 28-33″ slot (Atlantic and Gulf), one per day; seasonal closures vary by zone — verify FWC. Redfish: 18-27″ slot, one per angler per day (verify FWC zone-specific rules). Seatrout/Speckled Trout: FL: 15-19″ slot, 3 per day (verify zone). TX: 15-25″ slot, 3 per day. LA: 12″ minimum, 15 per day (verify current). Black Drum: 14-24″ slot or 16″ minimum depending on state; 1-5 per day. Always verify current state regulations before each trip — slots, bag limits, and seasons change.
