Swell Summary
Outlook through Wednesday May 23: Small north and northwest swells are expected Thursday through this weekend. Small south and southwest swells will maintain background surf along south facing shores through early Friday. A long-period south-southwest swell, expected to arrive late Friday, may produce a modest increase in surf heights along south facing shores this weekend. Expect choppy surf to increase slightly along east facing shores as the trades strengthen Friday through this weekend.
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.
