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 Saturday October 27: The current long period south swell is expected to produce well above normal surf through early next week. Re-enforcing south swells will keep south shore surf elevated through much of next week, with another Advisory level event possible by late next week or next weekend. Elsewhere, surf heights will remain below advisory levels through the middle to latter part of next week. A moderate short period north- northwest swell is expected to hold through tonight, then gradually drop Sunday through early next week. A moderate northwest swell is possible Tuesday through Thursday.
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.
