HIGH SURF WARNING FOR NORTH AND 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 Monday March 26: The incoming large northeast swell will steadily lower during the second half of the week, with the potential for advisory-level surf to continue into Friday for east-facing shores. Surf along south facing shores could trend up beginning Friday as a small southwest swell fills in.
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.
