September 04, 2018 Surf Forecast
Swell Summary
Outlook through Tuesday September 11: A large east swell generated by Hurricane Norman will begin to spread across the area tonight. This will cause surf to increase along east facing shores, with surf likely approaching the High Surf Warning criteria on Thursday. The east swell will gradually decline and shift to a northeast direction from Friday into this weekend. East Pacific Hurricane Olivia will likely produce a reinforcing east swell, which is expected to 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 this 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.
