Outlook through Thursday December 13: Surf along north and west facing shores should briefly drop below advisory levels Saturday, then quickly rise to warning levels along north facing shores Saturday night through Sunday as a large north swell fills in. Surf should drop below advisory levels by Monday as this source eases. A moderate northwest swell arriving on Tuesday could result in surf along north and west facing shores climbing back to advisory levels and holding through Wednesday before lowering. Surf along east facing shores will become rough over the weekend, likely reaching advisory levels due to strong trades.
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.
