Swell Summary
Outlook through Wednesday September 26: The current south swell will gradually decrease through Friday. Surf along east facing shores will build during the latter part of the work week as stronger trade winds return.
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.
