September 09, 2018 Surf Forecast
Outlook through Sunday September 16: Small long period swell from Hurricane Olivia will gradually increase through Monday and is expected to significantly increase Tuesday into Wednesday as Olivia nears the state. Surf is expected to rise into the solid advisory levels Tuesday and Wednesday and possibly to warning levels along east facing shores. Surf heights will be highly dependent on track and intensity of Olivia. Otherwise, a small, long-period southwest swell will provide a small bump to south facing shores today into Tuesday.
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.
