December 11, 2018 Surf Forecast
Outlook through Tuesday December 18: A new long-period northwest swell will arrive today, build tonight, then peak on Wednesday near advisory levels for north and west facing shores. This swell will slowly fade through the end of the work week, keeping surf elevated along north and west facing shores. A small reinforcement is expected on Friday out of the northwest. A new and larger northwest swell will likely bring advisory and possibly warning level surf to north and west facing shores late this weekend. Rough and choppy surf will persist along east facing shores for most of the week, gradually diminishing over 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.
