HIGH SURF WARNING FOR EAST 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 September 19: Swell from Tropical Storm Olivia will peak today, rising to warning levels along east facing shores. A small northwest swell is expected to fill in late today and peak Thursday. A small south swell is likely over the weekend, with another small northwest swell expected late in the weekend and 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.
