HIGH SURF ADVISORY 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 Tuesday February 27: A long period northwest swell is expected to arrive tonight and peak on Wednesday. This swell could approach advisory level on north and west facing shores. This swell will gradually subside Thursday, but another reinforcing northwest swell will move through Thursday night and Friday before fading on Saturday. Short-period east swell will continue to produce surf near advisory levels on east facing shores tonight, before possibly dropping below advisory levels Wednesday. Another boost on Thursday will likely bring advisory level surf back to east facing shores into the weekend.
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.
