August 13, 2018 Surf Forecast
Outlook through Monday August 20: The current south swell will gradually fade today, with only small surf then expected tonight through mid week. A series of small south swells may give a boost to surf along south facing shores Wednesday night into the upcoming weekend. A mix of small long-period east swell and trade wind energy will keep surf a bit elevated along east facing shores through tonight, with surf then lowering through midweek as the trade winds decrease. A very small northwest swell will be possible Wednesday through Thursday, boosting surf slightly along north facing shores.
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.
