HIGH SURF ADVISORY FOR EAST AND SOUTH FACING SHORES

Our weather team will bring you any urgent weather alerts or updates as they occur. Check our breaking news section for the latest.

Swell Summary

Outlook through Wednesday October 17: The current northwest swell will gradually decline over the next couple of days, with a small reinforcement due Thursday and Friday. A larger short-period north-northwest swell is expected to fill in late Sunday into Monday as a low pressure system near the Aleutian tracks southeast on Friday. A new pulse of long- period south- southwest swell is starting to fill in along south facing shores today. This swell is expected to peak later today into tonight at advisory levels. Additional small to moderate southwest swells are expected through the week. Surf along east facing shores will continue to hold steady today due to a mid to long- period easterly swell from former Hurricane Sergio in the eastern Pacific. This swell will decline on Thursday and Friday.
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.
