Swell Summary

Outlook through Friday July 20: A slight increase in trade wind swell is expected over the weekend and will hold steady into early next week. The current south swell will continue to decline through Saturday. A slightly larger southwest swell from the Tasman Sea, is expected to fill in Saturday night, peak Sunday night and slowly drop on Monday. A series of storms southeast of New Zealand this past week should provide surf near the summer average for the second half of next week. Surf heights along all shores are expected to remain below advisory levels.
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.
