Swell Summary
Outlook through Monday October 22: A large north-northwest swell is expected Tuesday and Wednesday, likely producing well above advisory-level surf along north and west facing shores. This source will slowly ease Thursday and Friday and may receive a small reinforcement over the weekend. After a slow decline during the middle of the work week, a late season pulse of south-southwest swell is due on Friday and will likely generate advisory-level surf along south facing shores through the weekend. Surf along east facing shores will slightly increase early during the next couple of days as moderate to fresh trades return locally.
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.
