Swell Summary
Outlook through Sunday August 26: A small, north-northwest swell is expected to arrive Monday and continue through Tuesday. A larger north swell is expected to arrive late Tuesday, peak Tuesday night and early Wednesday, then slowly fade through Thursday. Choppy surf along east facing shores will be on a gradual increase this week as trade winds strengthen. We will continue to monitor the track and intensity of Hurricane Lane as it moves closer to the islands, as this could result in a period of elevated surf along south facing shores during the middle of 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.
