Swell Summary

Outlook through Sunday November 25: The current north-northwest swell will continue to slowly decline today. Another moderate sized northwest swell is expected to fill in late Monday, peak Monday night and early Tuesday, then lower gradually into Wednesday. An uptick in short period choppy surf can be expected along east facing shores through the middle of this week due to the strong trades. Small, mainly background south swells are expected through the upcoming 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.
