Jacksonville is Florida’s first coast — the St. Johns River system, the Nassau River, the Intracoastal Waterway, and the Atlantic beaches converge in a diverse fishery that’s often overlooked compared to south Florida’s more famous destinations. That relative obscurity is an advantage for local anglers: less pressure, more fish, and excellent access from a major metropolitan area.
Top Species in Jacksonville Waters
Inshore: Redfish (the primary target throughout the system), flounder (excellent in the fall along the ICW and marsh drains), spotted seatrout, sheepshead (around docks and bridge pilings year-round), black drum, snook (southern end of their range — present year-round but sensitive to cold), and cobia (spring).
Nearshore / Offshore: Red snapper and grouper on offshore ledges 40–80 miles out, king mackerel (spring and fall), cobia (spring inshore), Spanish mackerel, and mahi on offshore color changes in summer.
Top Fishing Spots in Jacksonville
- Mayport Jetties: The mouth of the St. Johns River — some of the most productive jetty fishing in North Florida for flounder, redfish, sheepshead, snook, and large black drum. The north and south jetties both fish well; access the south jetty via Huguenot Memorial Park.
- St. Johns River: The river itself holds excellent redfish and flounder throughout, particularly around the ICW intersections, tributary mouths, and oyster bar systems.
- Nassau River / Fort George Island area: The northeast corner of the Duval/Nassau county line produces excellent redfish and seatrout in the salt marsh system.
- Pablo Creek / Fort Caroline area: Protected backcountry with consistent redfish, seatrout, and flounder accessible from multiple boat ramps.
- Atlantic Beach / Neptune Beach surf: Good pompano fishing in the surf October–April. King mackerel visible from the beach in spring and fall during bait runs.
Seasonal Fishing Calendar
Winter (December–February): Redfish in deep holes and around warm discharges. Sheepshead excellent on hard structure. Flounder in deeper channel edges.
Spring (March–May): Cobia following cownose rays along the beaches — March and April can be spectacular for sight-casting cobia from boats running parallel to the beach. Spanish mackerel arrive. Redfish on the flats as water warms.
Summer (June–August): Flounder active in ICW and marsh drains. Tarpon occasional in the river. Offshore snapper and grouper season. Early morning topwater redfish on the flats.
Fall (September–November): The best time of year — redfish school up, flounder peak (October is the best flounder month), seatrout active, and offshore king mackerel near the beaches during the bait run.
