Swell Summary

Outlook through Thursday January 24: A short to mid period pulse from the northwest will boost surf to at or near advisory levels for the west and north facing shores tonight through Friday before fading over the weekend. East facing shores will see a slight bump up over the weekend due to the return of locally strong trade winds. A series of small to moderate northwest swells is expected through early next week and will be followed by larger northwest swells towards the middle of 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.
