December 2025 — Fort Myers / Sanibel: Sheepshead, Canal Snook, Winter Pattern Returns. December is a early winter month with water in the 60–68°F range — sheepshead returning to structure; redfish in deep holes; pattern shifts to winter mode. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics for this month.
What’s Biting — December 2025
Primary targets this month: Sheepshead, Snook, Redfish, Seatrout.
Sheepshead
Sheepshead are stacked on hard structure for the winter spawn. Target the Sanibel Causeway pilings, the Cape Coral Bridge, the Edison Bridge, Bokeelia pier, and Matlacha Bridge. Use fresh fiddler crabs or live shrimp on a #1 or #1/0 octopus hook with just enough split shot to hold bottom — sheepshead bite light, so feel for the slightest tap and set immediately. Vertical jigging right along pilings produces best; cast away from the structure and you’ll miss most of them.
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
Winter reds 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. Look for the warmest water in the system — dark mud bottoms, deeper canals, and creek mouths that warm fastest on sunny afternoons. Slow-rolled gold spoons, scented soft plastics on 1/4 oz jigheads, and live shrimp under a popping cork are reliable. Sight-fishing tailing reds on sunny low-tide flats is possible on the warmest afternoons.
Seatrout
Seatrout are gathering in the deep grass flats of Pine Island Sound, San Carlos Bay, and Matlacha Pass; potholes in 4–6 feet hold the biggest fish. Larger fish (gator trout 20″+) hold in deeper potholes in 4–6 feet. Soft plastic paddletails (DOA CAL, MirrOlure Lil John) on 1/4 oz jigheads, MirrOdine suspending baits, and live shrimp under popping corks are the standard producers. Slow your retrieve as water cools.
Water Conditions & Patterns
Water temperatures are running 60–68°F. Sheepshead returning to structure; redfish in deep holes; pattern shifts to winter mode. 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
- Slow it down. Cold water means cold fish — work jigs, soft plastics, and live bait with extreme patience. Bites are subtle.
- Fish the warmest water. Dark-bottom flats, deeper canals, and creek mouths warm fastest. Afternoons (after 2 PM) usually outproduce mornings in winter.
- Light fluorocarbon leader. 15–20 lb is plenty for inshore — winter water clarity is high and fish are line-shy.
December Outlook
Pattern shifts fully to winter — sheepshead return to structure, redfish concentrate in deep holes. By month’s end, the winter regime is locked in.
