This page covers sailfish fishing from Mayport, the First Coast port at the mouth of the St. Johns River. Sailfish are not documented from Mayport itself. What is documented is a summer-into-fall window for the offshore water off Jacksonville, a Gulf Stream distance, and several named reefs and wrecks that are not tied to sailfish. This page says what is known and what is not. The Atlantic Southeast sailfish guide (see also the Atlantic Southeast region guide) covers the wider coast, and the Mayport port page covers the port itself.
When the species is around the port
A single spot review for the offshore water off Jacksonville gives May through October as the best period for sailfish, mahi-mahi and blackfin. The review describes Jacksonville offshore water rather than Mayport itself, so treat the window as a marker, not a Mayport schedule. The regional pattern agrees that sailfish move north along the Stream as summer warmth arrives. No month is documented for Mayport specifically.
Where boats run
One spot review places the Gulf Stream roughly 40 to 60 miles from Jacksonville Beach. That makes the offshore run a long one. Check conditions yourself before you run offshore, and read the marine forecast for wind, seas and period before you commit to the trip.
Grounds and structure
Several named reefs and wrecks lie offshore of Mayport, but none is documented as sailfish water. Nine Mile Reef sits a few miles from the Mayport jetties and has five wrecks. Spike Reef sits at about 110 feet, with several hundred yards to the next reef, and the steel ship Anna lies at about 100 feet. Blackmar’s Reef holds five wrecked ships and two planes, with no depth given. Treat them as structure to know about, not as sailfish grounds.
How sailfish are fished out of the port
No Mayport method for sailfish is documented. The regional standard north of Stuart is trolled ballyhoo with teasers and dredges, and a pitch bait on a circle hook takes the fish when a sail rises behind the teaser. Kites and live bait are the Southeast Florida method, and they suit fish working an edge. Keep a rigged ballyhoo ready, let the circle hook set in the corner of the jaw on steady pressure, and release the fish in the water.
Who fishes it
No sailfish charter or tournament out of Mayport is documented.
Frequently asked questions
Is there a sailfish season at Mayport?
No Mayport-specific season is documented. The best window for the offshore water off Jacksonville is May through October, and that is the window to test on your own trips.
How do I tell a sailfish from a white marlin?
A sailfish’s first dorsal is a tall sail that runs most of the back. A white marlin’s dorsal is shorter, with a rounded tip. If you are unsure, release the fish.
Are the named reefs sailfish water?
None is documented as sailfish water. Use the reefs as known structure, and read the Gulf Stream edge on the map for the sailfish water instead.
