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 Sunday October 28: The current south swell will hold today, then gradually lower tonight and Monday. Re-enforcing south swells will keep south shore surf elevated through next weekend, with surf heights possibly rising to advisory levels once again during the second half of the work week. Elsewhere, surf heights will remain below advisory levels through the work week. A moderate short period north swell is expected to gradually drop today through Monday. A moderate north- northwest swell is expected to build on Tuesday, peak on Wednesday, then slowly decline through the end of the work 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.
