Swell Summary
Outlook through Wednesday November 28: Rough surf will continue along east facing shores due to strong trades. A moderate northwest swell is forecast to begin filling in on Saturday with a larger and longer period northwest reinforcement expected Saturday night and Sunday. Advisory-level surf is expected with this longer period swell. The largest swell of the season will be possible next Monday with heights potentially exceeding warning levels.
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.
