Swell Summary

Outlook through Friday August 03: Breezy trade winds will generate modest choppy surf along east facing shores into early next week. A long fetch of strong trade winds developing east and northeast of the islands next week may cause a slight increase in surf heights along east facing shores by the middle of next week. Small southeast and south swells will maintain small background surf along south facing shores through the middle of next next week.
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.
