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.
Fishing Licenses
Florida saltwater fishing license required. Redfish: 18–27″ slot, 1 fish per day on the Atlantic coast. Flounder: 12″ minimum, 10 fish per day. Snook: 28–33″ slot, 1 fish per day, Atlantic coast seasons apply.
Plan Your Jacksonville Fishing Trip
Jacksonville combines the lower St. Johns River, miles of tidal creeks and marsh, major jetties, Atlantic beaches, and offshore reefs. Check the latest Jacksonville fishing report, the report archive, and the seasonal fishing calendar before choosing a zone.
Fish marsh drains, oyster edges, creek bends, and flooded grass for redfish, trout, flounder, and sheepshead. The jetties add bull redfish, black drum, flounder, mackerel, and sharks, but require heavier tackle and careful boat positioning. Beaches produce whiting, pompano, bluefish, and seasonal pelagics; offshore reefs add snapper, grouper, cobia, and kingfish.
Boat Ramps and Public Access
- Mayport Boat Ramp: direct access to the lower river and inlet approaches.
- Sisters Creek Park and Boat Ramp: useful for the Intracoastal and marsh creeks.
- Oak Harbor Boat Ramp: access to protected tidal water north of the river.
- Huguenot Memorial Park: shoreline access near the inlet; tides and posted driving rules matter.
Verify ramp status, fees, and park hours. The St. Johns carries commercial traffic and strong current, while oyster bars and changing shoals create shallow-water hazards.
Local Strategy and Regulations
Time creek mouths and oyster points with moving water. Use medium tackle in open marsh and stronger leader around rocks, docks, and bridge structure. Check current FWC and federal regulations and seasons before harvest. For beach setups, see our surf rods under $200 guide.
