December 31, 2018 Surf Forecast
Swell Summary
Outlook through Monday January 07: A new small northwest swell will build today, then peak well below advisory levels tonight. A larger northwest swell will build Tuesday and Tuesday night, then peak at or near advisory levels Wednesday through Thursday. Persistent moderate to strong trades will result in elevated surf along east facing shores through much of the week, with advisory level surf possible at times, Tuesday through late in the week.
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.
