December 10, 2018 Surf Forecast
Swell Summary
Outlook through Monday December 17: A long-period northwest swell arriving Tuesday will peak Wednesday, bringing surf along north and west facing shores close to advisory levels. This swell will slowly fade through the end of the work week, keeping surf elevated along north and west facing shores. A new and larger north-northwest swell will likely bring advisory and possibly warning level surf to north and west facing shores late next 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.
