October 14, 2018 Surf Forecast
Outlook through Sunday October 21: A large northwest swell is expected Tuesday through midweek, that will likely generate advisory-level surf along north and west facing shores late Tuesday through Wednesday. This source will slowly ease through the second half of the week. Another advisory-level south swell is expected late in the week, which will be a long-duration episode, likely holding through next weekend. Surf along east facing shores will slightly increase early in the week as moderate 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.
