Outlook through Friday September 14: A large east swell generated by Hurricane Norman will gradually decline and shift out of the northeast tonight and Saturday. Another east swell from Hurricane Olivia arrive on Sunday and build through early next week, possibly bringing warning level surf by mid week. Otherwise, small south and southwest swells will maintain small background surf along south facing shores through early next week.
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.
