March 18, 2018 Surf Forecast
Outlook through Saturday March 24: Small northwest and north swells will continue through the next couple of days. Surf will stay below advisory levels along north and west facing shores. A larger and longer period northeast swell will arrive Wednesday and peak Wednesday night into Thursday. Surf along north and east facing shores will reach advisory level surf with this swell, possibly warning level heights for east facing shores at the peak. 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.
