February 20, 2018 Surf Forecast
Swell Summary
Outlook through Monday February 26: A long period northwest swell arriving Tuesday night and peaking Wednesday may produce surf approaching the advisory level on north and west facing shores. This swell will gradually subside Thursday, but another reinforcing northwest swell will move through Thursday night and Friday before fading on Saturday. Short-period east swell will continue to produce surf near advisory levels on east facing shores Wednesday and Thursday, with the swell and surf building further on those shores Friday into 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.
