Swell Summary

Outlook through Friday December 28: A series of small, north and northwest swells will affect north and west facing shores today through the weekend. A moderate to large northwest swell is expected to arrive Monday, and persist through the middle of next week. This swell is expected to bring advisory level surf to north and west facing shores exposed to the swell. A larger northwest swell will be possible late next week, possibly bringing another round of warning level surf to north and west facing shores. Short period choppy surf can be expected along east facing shores throughout the forecast period. Small, mainly background south swells can be expected through the remainder of the week and on into early next week.
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.
