Swell Summary
Outlook through Sunday May 27: Surf along east facing shores will remain rough through the week. A new south swell is expected for the second half of the week. A small northwest swell is possible Wednesday.
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.
