December 25, 2018 Surf Forecast
Outlook through Tuesday January 01: Surf will begin to rise by the end of the day Thursday, potentially reaching warning levels Thursday night through Friday along exposed north and west facing shores as a larger northwest swell fills in. Surf will slowly lower over the upcoming weekend along north and west facing shores as this swell eases. Small to moderate trade wind swell will keep the surf up along east facing shores into the second half of the week as the winds become light locally. Surf could near advisory levels once again early next week along exposed north and west facing shores as another long-period west-northwest swell fills in.
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.
