Swell Summary
Outlook through Tuesday November 27: The small northwest swell peaking today will lower gradually through midweek. Another northwest swell is forecast to begin filling in on Saturday with a larger and longer period northwest swell expected Saturday night and Sunday. Advisory-level surf is possible with this longer period swell. The largest swell of the season will be possible next Monday with heights potentially exceeding warning levels. Specifics will come in later forecasts as confidence rises.
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.
