Spanish run the beaches and nearshore reefs — 1-15 miles off the 904 coast — when water temps are right. They follow bait schools (glass minnows, pilchards) and crash into them aggressively. Mayport, the Jax Beach pier, and offshore reefs (4-10 miles) all hold them in season.
Slender silver body with bronze-yellow oval spots scattered along the sides. Florida minimum 12 inches fork length, daily bag of 15. Most are 1-3 lb in NE FL; 5+ lb is a big one. Distinguished from king mackerel by the spots and smaller size.
Spring (April-May) and fall (September-November) are the marquee windows — water temps in the 68-75°F range. Summer they push offshore into deeper water; winter they're south of the 904. When the run is on, the action can be every-cast nonstop.
Look for diving birds and busting bait near the beach or at the jetty mouth. Cast a small silver spoon, a Gotcha plug, or a metal jig and burn it back fast. Use a short fluoro bite leader (12 inches of 30 lb) — Spanish have small but sharp teeth that fray light line. From the pier, walk the south end at the start of incoming tide for the highest-percentage shot.
Florida fishing regulations change. Always confirm slot, bag limits, and seasons on the official source before you keep anything. See our Licenses & Regulations page or go straight to MyFWC.com.
