Q.SST & Offshore Fishing
What SST triggers king mackerel migration?
A.
King mackerel migrations are triggered when SST drops below 68-70°F in their summer range. Spring migration northward begins when nearshore water hits 68-72°F. Fall migration south begins as water drops below 70°F. The Mid-Atlantic king run typically peaks in summer; Florida sees year-round populations because water stays warm.
