January 09, 2019 Surf Forecast
Outlook through Wednesday January 16: The current long period north-northeast swell is expected to cause surf to reach the High Surf Advisory conditions along east facing shores later today, and near advisory levels for north facing shores. Otherwise, small to moderate northwest swells will persist through Friday. A large northwest swell arriving late Friday night may increase surf to the High Surf Warning criteria along north and west facing shores this weekend. This northwest swell will remain elevated into early next week, so advisory level surf may persist next Monday and Tuesday.
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.
