December 09, 2018 Surf Forecast
HIGH SURF ADVISORY FOR WEST AND EAST FACING SHORES
Our weather team will bring you any urgent weather alerts or updates as they occur. Check our breaking news section for the latest.
Outlook through Sunday December 16: A long-period northwest swell arriving Tuesday will peak Wednesday, bringing advisory-level surf to north and west facing shores. A moderate-sized north-northwest swell is possible late Thursday into Friday. Rough and choppy surf will persist along east facing shores for most of the week, gradually diminishing next 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.
