Swell Summary
Outlook through Tuesday August 28: Choppy surf along east facing shores will gradually increase this week as trade winds strengthen. Most importantly, Hurricane Lane is forecast to pass south and southwest of the islands this week, and is expected to bring rough and extra large surf to south facing shores Thursday and Friday. Be sure to monitor forecast updates on Lane as it could bring significant impacts later this 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.
