May 2026 — Mississippi Gulf Coast: Tarpon Building, Red Snapper Opener Looming. 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 2026
Primary targets this month: Speckled Trout, Redfish, Mangrove Snapper, Tarpon.
Speckled Trout
Summer trout in the Mississippi Sound (Biloxi Marsh, Bay St. Louis, Pascagoula River mouth), the barrier island flats (Cat Island, Ship Island, Horn Island), and the deeper sound holes — Mississippi is the speckled trout capital of the Gulf — 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 Biloxi Marsh, Bay St. Louis flats, Pascagoula River mouth, the barrier islands’ interior bays, and the rip-rap shorelines. Fish dawn and dusk — once water hits 85°F bites slow significantly. Live pinfish, cut ladyfish, topwater walking baits at first light.
Mangrove Snapper
Mangrove snapper on the offshore oil platforms (the Mississippi rigs — same fishery as Louisiana), the nearshore artificial reefs. Live shrimp on light leader around bridges and structure.
Tarpon
Peak tarpon season. Fish stacked on the Mississippi Sound from July through September — Cat Island, Ship Island, the deeper Sound, the river mouths. 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.
Water Conditions & Patterns
Water temperatures are running 74-80°F. Tarpon arriving gulf passes; offshore action builds. Mississippi Sound has minimal tide range (1-1.5 ft) — wind dominates the fishery. South winds push water and bait into the marsh; north winds drop water and concentrate fish in the deeper Sound holes. The passes (Pass Christian, Biloxi Bay, Pascagoula) run on real tidal current and fish best on outgoing.
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.
