Q.Inshore Migration Timing
When do Spanish mackerel arrive in spring?
A.
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.
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.
