Tides & Timing β€” Northeast Florida Cheat Code

The Golden Rule

Mayport Jetties is the key to Northeast Florida fishing. Incoming tides funnel baitfish and flounder into the deep channels. Outgoing tides push snook and other predators through the inlet mouth. St. Augustine Inlet is another major funnel. Amelia Island flats fish best on low tide with gin-clear water.

Incoming Tide

Baitfish and flounder push into Mayport channels. Deep channel edges come alive.

High Tide

Snook push into mangrove creeks. Work tree lines and marker poles.

Outgoing Tide

Mayport and St. Augustine inlets are funnels. Snook and flounder concentrate at inlet mouths.

Low Tide

Sight-fish tailing reds on Amelia Island flats. Gin-clear water enables sight-casting.

Top Spots by Season

Spring (Mar–May)

Snook spawn run at inlets. Bluefish appear nearshore. Redfish activate on flats.

Summer (Jun–Aug)

Night snook under dock lights. Morning flounder jigging at Mayport. Backcountry action in creeks.

Fall (Sep–Nov)

Bluefish school at Mayport. Flounder migration begins. Sheepshead appear at pilings.

Winter (Dec–Feb)

Sheepshead peak at Mayport. Flounder dominate channels. Cold snaps trigger big fish.
