September 10, 2018 Surf Forecast
Outlook through Monday September 17: Swell from Hurricane Olivia will gradually increase through Tuesday and is expected to significantly increase Tuesday evening 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 Tuesday night into Wednesday along east facing shores. Currently, exposed north facing shores are seeing swell from former tropical cyclone Norman. This swell is expected to fade into Tuesday. A small northwest swell is expected to fill in late Wednesday and peak on Thursday. Otherwise, a small, long-period southwest swell will provide a small bump to south facing shores into Tuesday. Another small south swell is expected over the weekend.
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.
