Outlook through Saturday July 21: Fresh to locally strong trade winds will continue to produce rough and choppy surf along east facing shores through early next week. A new southwest swell from the Tasman Sea is expected to fill in tonight, peak Sunday night and slowly drop on Monday. A series of storms south and southeast of New Zealand over the past several days should provide surf near the summer average for the second half 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.
