March 2026 — Fort Myers / Sanibel: Cobia at Pine Island Sound, Permit on Gulf Flats, Spring Begins. March is a early spring month with water in the 62–70°F range — cobia migration in full effect; inshore species moving from winter holes to flats. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics for this month.
What’s Biting — March 2026
Primary targets this month: Cobia, Snook, Redfish.
Cobia
Peak cobia migration. Sight-fishing along the beach, around Boca Grande Pass, the nearshore reefs (ARC, Bokeelia Wreck), and pots/buoys in 30–60 feet, and following stingrays in clear water is the move. You need calm seas (1–2 ft) and sun overhead to spot fish. Run the beach 1/4 to 1/2 mile off the sand looking for dark torpedoes — single fish, pairs, or pods of 4–6. Cast 4–6″ bucktails (chartreuse, white, pink), large soft plastic eels, or live eels and pinfish. Cobia will often follow the boat after first refusal, so make a second cast.
Snook
Snook are in the mangrove shorelines of Pine Island Sound, Matlacha Pass docks, the Caloosahatchee River bridges (Edison, Midpoint, Cape Coral), and the Sanibel Causeway. Live pilchards, scaled sardines, and finger mullet are top live baits. Artificial: white DOA Bait Buster, MirrOdine, and walking topwaters at first and last light. Always check current FWC snook season dates — slot is 28–33″ Atlantic, 28–33″ Gulf, with seasonal closures.
Redfish
Redfish are in Pine Island Sound mangrove edges, the Matlacha Pass flats, San Carlos Bay, Tarpon Bay (Sanibel), and the oyster bars north of Cabbage Key. Cut bait, gold spoons, and soft plastics on light jigheads all produce. Match the tide and look for activity on shorelines with clean water.
Water Conditions & Patterns
Water temperatures are running 62–70°F. Cobia migration in full effect; inshore species moving from winter holes to flats. Pine Island Sound and Matlacha Pass fish best on the early stages of incoming and outgoing tide — strong current pushes bait out of the mangroves. Boca Grande tarpon fishing is built around the strong tides at the pass; check the SOLUNAR major periods for peak bites.
Check the NOAA marine forecast and tide charts before launching. Wind direction matters more than wind speed for inshore fishing — east winds tend to push clean water in, while strong westerlies can muddy the bays.
Tactics & Tackle for This Month
- Cobia readiness. Keep a heavy spinning rod (8000-class reel, 40–50 lb braid, 60–80 lb fluoro leader) 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 (amber or copper for clarity) are essential.
- Bait migration. Spanish, kings, and predators follow bait pods — keep an eye on diving birds and surface activity.
March Outlook
Cobia migration intensifies through the month and peaks in April. Inshore species (snook, redfish, seatrout) shift from winter holes onto warming flats.
Regulations Reminder
Snook: 28–33″ slot (Atlantic), 28–33″ slot (Gulf), one fish per angler per day; seasonal closures apply (typically Dec 15–Jan 31 and Jun 1–Aug 31 on Gulf; Dec 15–Jan 31 and Jun 1–Aug 31 on Atlantic — verify current FWC dates).
