March 2026 — St. Augustine / Northeast FL: Cobia Migration, Spring Reds Moving to Flats. 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, Redfish, Speckled Trout, Sheepshead.
Cobia
Peak cobia migration. Sight-fishing along the beach, around the offshore wrecks and reefs, the artificial reefs, and following stingrays on the beach in spring, 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.
Redfish
Redfish in the Tolomato River, Salt Run, Matanzas River, the Guana River, the marshes south of St. Augustine, and the Tolomato bird island flats. Cut bait, gold spoons, and soft plastics on light jigheads.
Speckled Trout
Trout holding in the deep grass flats of the Matanzas, the Tolomato channels, Salt Run, and the back bays of Vilano Beach. Live shrimp under a popping cork, soft plastic jigs in natural colors (root beer, new penny, opening night).
Sheepshead
Sheepshead are stacked for the winter/early-spring spawn. Target the St. Augustine Inlet jetty, the Bridge of Lions, the Vilano Bridge, the marina pilings. Fresh fiddler crabs and live shrimp on a #1 or #1/0 octopus hook with minimal weight. Bites are subtle — set on the slightest tap. Vertical jigging tight to structure produces best.
Water Conditions & Patterns
Water temperatures are running 60-68°F. Cobia migration building; inshore species moving onto warming flats. St. Augustine Inlet moves significant water — outgoing tide concentrates bait at the jetty and is the prime snook/tarpon window. The Tolomato and Matanzas Rivers are heavily tide-driven; falling water out of the marsh creeks concentrates redfish at the creek mouths.
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
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.

Always verify current state regulations before each trip — slots, bag limits, and seasons change.
