Outlook through Friday April 20: The current northwest swell will peak Saturday morning, slowly subside through Saturday night, then quickly drop Sunday. A small north swell will gradually build Wednesday night, with a moderate northwest swell expected Thursday night, but should remain below advisory level. As trade winds strengthen this weekend, rough surf along east facing shores will reach advisory levels later Saturday and remain elevated into early next week. Surf along south facing shores will increase a bit later this weekend.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
