HIGH SURF ADVISORY FOR SOUTH 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 Friday October 19: The current southwest swell will gradually decline this weekend. The current northwest swell will fade through Saturday. A moderate north northwest swell will arrive Sunday and peak Sunday night. A larger northwest swell Monday night may produce advisory level surf along north and west facing shores by 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.
