Swell Summary

Outlook through Saturday September 22: Choppy surf will continue along east facing shores through the weekend. Surf will drop below average levels along east facing shores middle of next week as trade winds weaken. Small background reinforcing south and south-southwest swells will continue to generate small surf along south facing shores through early next week. A larger south swell is expected Tuesday through midweek. A small northwest swell is expected to fill in Sunday night and peak Monday and 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.
