Outlook through Friday May 18: A series of small north-northwest swells will continue through early next week. Small background south-southwest swells will persist through the weekend, followed by a moderate long period south swell that will peak Monday and Tuesday. Small east shore surf is expected increase to moderate levels as trade winds rebuild 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.
