March 17, 2018 Surf Forecast
Outlook through Friday March 23: A small northwest swell will build tonight and peak tomorrow night, with another small reinforcing northwest swell forecast to peak Sunday night. Surf will stay below advisory levels with both of these events. A short period northeast swell is expected to produce choppy surf along the east facing shores from Sunday into Tuesday before a larger and longer period northeast swell arrives Wednesday and peaks Wednesday night into Thursday. Surf along north and east facing shores could see advisory level surf with this swell. Surf along south facing shores should see above null conditions for a next few days with small long period background swells moving through.
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.
