Swell Summary
Outlook through Thursday November 22: A new northwest swell is expected to fill in tonight, peak on Friday at advisory levels along north and west facing shores, then lower gradually Friday night and Saturday. A slightly smaller north northwest swell is expected Saturday night and Sunday. Another small to moderate size northwest swell is expected to arrive on Monday. Small, mainly background south swells are expected through the remainder of the week and on through the weekend. A slight uptick in short period choppy surf can be expected Friday through Sunday as the trade winds strengthen.
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.
