Swell Summary

Outlook through Friday May 25: Surf along east facing shores will steadily rise and become rough over the weekend as strong trades persist. Surf along south facing shores will rise over the weekend as two new long-period south southwest swells fill in. Another long period south swell will remain possibleduring the second half of next week. Surf along north facing shores will steadily lower through Sunday and remain low through the beginning of next week. A small boost to the northwest swell is expected around 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.
