Swell Summary
Outlook through Thursday September 13: A large east swell generated by Hurricane Norman is expected to peak later today. The east swell will then gradually decline and shift to a northeast direction from Friday into this weekend. Hurricane Olivia could produce another large east swell, which may bring surf to advisory or warning levels early next 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.
