Swell Summary
Outlook through Saturday September 15: The current swell, generated from Tropical Cyclone Norman, will continue to subside and turn out of the northeast today. Advisory level surf is expected along exposed east facing shores through this afternoon. Another east swell from the westward advancing Hurricane Olivia is forecast to begin arriving on Sunday and will continue to build through early next week, possibly bringing warning level surf back to east facing shores by mid week. The surf forecast surrounding the Hurricane Olivia swell will be highly dependent on track and intensity. A small long period southwest swell will provide a small bump to south facing shores from Sunday night 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.
