Outlook through Thursday August 23: Overall, small surf is expected along all shores through the weekend. A small south-southeast swell is expected to fill in today, peak tomorrow and hold through Saturday at heights below the summer average. Models are suggesting a broad area of low pressure developing near the Aleutian Islands this weekend. This may bring a small to moderate north to north-northwest swell starting around Monday night or Tuesday of next week. We will continue to monitor the development of tropical cyclone Lane for any surf potential.
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.
