Outlook through Saturday December 29: A series of small, northwest swells will affect north and west facing shores through the weekend. A moderate northwest swell is expected to arrive Monday and peak Monday night followed by a larger northwest swell building Tuesday and peaking Tuesday night. The latter swell could bring advisory level surf to exposed north and west facing shores. An even larger northwest swell will be possible late next week, possibly bringing warning level surf to north and west facing shores. Elsewhere, short period choppy trade wind surf can be expected along east facing shores throughout the forecast period. A slight bump in surf along south facing shores is possible Sunday into the beginning of next week as a very small, long period south swell fills in. Otherwise, mainly background south swells can be expected.
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.
