Outlook through Monday December 24: The current long-period northwest swell will continue to steadily subside today. A new, larger northwest swell is expected to build tonight, bringing another round of warning level surf to north and west facing shores Tuesday through the middle of next week. Several small northwest swells are expected towards the end of the week into 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.
