Swell Summary

Outlook through Saturday January 26: The current north-northwest swell will gradually decline through the weekend, followed by a series of overlapping northwest swells next week. The first swell will produce moderate surf below advisory levels Monday and Tuesday. The next swell will arrive Tuesday and result in surf well above advisory levels for north and west facing shores Tuesday night and Wednesday. As this swell declines Thursday, a large reinforcing northwest swell will build, possibly leading to warning level surf late Thursday and Friday. Short period swell from the east will produce a small bump in east shore surf this weekend, with another increase possible around Wednesday. No significant south swells are due.
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.
