It depends on what you’re after! For the Pacific side, winter (Nov-March) brings consistent NW swells and offshore winds, with bigger, colder waves up north. Summer (June-Oct) is for the East Cape and the Sea of Cortez, with south swells from hurricanes and tropical storms bringing warm water and fun waves. Spring and fall can be hit-or-miss but offer fewer crowds. Basically, chase winter for power, summer for warmth, and always check the charts.
