Swell Summary
Outlook through Thursday August 30: Life-threatening surf and rip currents will likely continue along south facing shores through Saturday as Lane continues to impact the state. A gradual downward trend is anticipated Sunday through early next week as Lane moves west of the region and continues to weaken. Advisory surf is likely along east facing shores Friday through Saturday due to increasing onshore winds north of Lane.
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.
