December 16, 2018 Surf Forecast
Swell Summary
Outlook through Sunday December 23: The current long-period northwest swell will peak today, and gradually subside through Monday. A new, larger northwest swell is expected to build Monday night, bringing another round of warning level surf to north and west facing shores Tuesday through the middle of next 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.
