HIGH SURF ADVISORY FOR NORTH AND WEST FACING SHORES

Our weather team will bring you any urgent weather alerts or updates as they occur. Check our breaking news section for the latest.

Swell Summary

Outlook through Wednesday October 24: The current large north-northwest swell will peak today and then ease Thursday through Friday. A smaller north swell is possible over the weekend, with peak surf heights below advisory levels. Surf along south facing shores will remain elevated, but below advisory levels, through today. A new large south swell is expected to arrive Friday, peaking near warning levels Saturday into Sunday.
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.
