Swell Summary

Outlook through Wednesday March 21: The current north swell will continue to gradually diminish through Thursday. As the trade winds weaken and shift to a southeast direction tonight and Thursday, expect surf to diminish along east facing shores. Small north and northwest swells arriving this weekend may produce slight bumps in surf along north and west facing shores from Saturday through 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.
