March 2026 — Charleston / Lowcountry SC: Cobia Migration Through Charleston Harbor. March is a early spring month with water in the 44-54°F range — striped bass begin moving; spring tautog peak; perch in tributaries. 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, Sheepshead, Cobia.
Redfish
Redfish in the Charleston Harbor flats (Crab Bank, the Stono River, the Wando River backwaters), Mount Pleasant marshes, Folly Beach surf and inlet, Edisto, Bulls Bay, and Bohicket Creek. Cut bait, gold spoons, and soft plastics on light jigheads.
Speckled Trout
Trout holding in the grass flats and creek mouths of Charleston Harbor, the Stono and Wando, Bulls Bay marshes, Hilton Head approach, and the inshore creeks. 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 Charleston Battery seawall, the Cooper River bridges, the harbor’s barge wrecks, dock pilings of Mount Pleasant and Folly. 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.
Cobia
Peak cobia migration. Sight-fishing along the beach, around the Charleston Harbor jetties and nearshore reefs in spring (April-May), Edisto Beach, and the offshore wrecks, 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.
Water Conditions & Patterns
Water temperatures are running 44-54°F. Striped bass begin moving; spring tautog peak; perch in tributaries. Charleston has a major tidal swing (5-6 ft) — the marsh fishery is entirely tide-driven. Falling water out of the marsh creeks concentrates redfish at the mouths; rising water spreads them across the flats. The first two hours of the outgoing tide universally produce best on the inshore. The harbor jetties run hard 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
- Striped bass migration. Watch water temperatures — 50°F triggers the spring run.
- Pre-spawn tautog peak. Best blackfish window of the year — wrecks and rocky structure.
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. LA: 12″ minimum, 15 per day (verify current). Sheepshead: 12″ minimum, 8 per day (FL). 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.
