Swell Summary
Outlook through Tuesday May 22: The current small north-northwest swell will diminish through Wednesday. Another round of small north to northwest swells are forecast Thursday through the weekend. A series of small south swells will continue to roll into south facing shores through the 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.
