Swell Summary

Outlook through Friday September 21: Choppy surf will continue along east facing shores through the weekend. Small background reinforcing south and south-southwest swells expected over the weekend will continue to generate small surf along south facing shores. A moderate south swell is expected Tuesday through midweek. A small northwest swell is expected to fill in Sunday night through Monday. A small west swell can’t be ruled out by midweek.
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.
