August 31, 2018 Surf Forecast
Swell Summary
Outlook through Friday September 07: A small south swell is expected to begin filling in today, peak late tomorrow near the summer average, then subside through Monday. Swells from Hurricane Miriam will spread to east facing shores over the weekend as Miriam moves north and weakens. This surf will remain below the advisory threshold. Swells from Hurricane Norman will reach Oahu during the second half of next week and could produce advisory level surf along east facing shores.
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.
