September 05, 2018 Surf Forecast
Swell Summary
Outlook through Wednesday September 12: A large east swell generated by Hurricane Norman will gradually increase throughout the day today and will continue to rise through Thursday. The east swell will gradually decline and shift to a northeast direction from Friday into this weekend. Hurricane Olivia could produce a reinforcing east swell, which may provide a boost in surf along east facing shores starting Sunday. 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.
