Spanish mackerel will stay through summer and fall before moving south as water cools below 65°F. SST threshold pages cover the temperature signals that drive their migration; migration calendar pages cover regional timing.

When do Spanish mackerel arrive in spring?
Spanish mackerel arrive in spring as Atlantic and Gulf coast water temperatures hit the 65-68°F threshold — typically late April in the Carolinas, mid-May in the Mid-Atlantic, and progressively later northward. They follow bait pods (anchovies, glass minnows) along the beach and into bay mouths.
