Outlook through Thursday October 18: A small reinforcement northwest swell is expected to fill in today and hold through Friday. A larger short-period north-northwest swell is expected to fill in late Sunday into Monday as a low pressure system near the Aleutian tracks southeast today through Friday. The current long-period southwest swell is expected to today and gradually decrease through the rest of the week. Additional small to moderate southwest swells are expected over the weekend. Surf along east facing shores will hold through today due to a combo trade wind swell and a declining east swell from former Hurricane Sergio. Looking out into next week, a large north-northwest swell is expected around Tuesday and is expected to reach advisory levels along north and west facing shores.
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.
