March 2026 — Stuart: Cobia Arrive, Mahi Season Beginning, Tarpon Entering the System. March is a early spring month with water in the 60-68°F range — cobia migration building; inshore species moving onto warming 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: Cobia, Sailfish, Snook, Redfish.
Cobia
Peak cobia migration. Sight-fishing along the beach, around the St. Lucie Inlet, the Crossroads area, and bait pods on the beach 1/4 to 1/2 mile out, and following stingrays in clear water. Need calm seas (1-2 ft) and sun overhead. 4-6″ bucktails (chartreuse, white, pink), large soft plastic eels, or live eels and pinfish. Cobia often follow first refusals — make a second cast.
Sailfish
Peak sailfish season on the Push Button Hill area off Stuart, the color change at 100-200 feet, the Loran Tower numbers, and the Bahamas current edge. Live bait (goggle-eyes, threadfins) on kites or slow-trolled. North current with falling barometer triggers the best bites. The Stuart-Palm Beach-Fort Lauderdale corridor is the East Coast sailfish capital.
Snook
Snook in the St. Lucie Inlet jetty, the Crossroads (where the St. Lucie meets the Indian River), the Roosevelt Bridge, the Hells Gate area, and the docks of Sewall’s Point. 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.
Redfish
Redfish in the spoil islands of the IRL, Manatee Pocket, Jensen Beach Causeway flats, and Bird Island shorelines. Cut bait, gold spoons, and soft plastics on light jigheads.
Water Conditions & Patterns
Water temperatures are running 60-68°F. Cobia migration building; inshore species moving onto warming flats. St. Lucie Inlet moves serious water; outgoing tide concentrates bait and game fish in the Crossroads area. The first two hours of incoming tide push clean blue Gulf Stream water in.
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). Cobia: 36″ fork length, one per harvester (FL state waters — verify current rules). Always verify current state regulations before each trip — slots, bag limits, and seasons change.
