HIGH SURF ADVISORY FOR NORTH, WEST 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 Saturday April 21: The current northwest swell will quickly drop Sunday. A small north swell will gradually build Wednesday night, with a moderate northwest swell expected Thursday night, but should remain below advisory level. Strengthening trade winds will produce advisory level rough surf along east facing shores through Sunday and remain elevated into early next week. Surf along south facing shores will get a slight bump late this weekend into 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.
