Swell Summary
Surf along south-facing shores will remain below average into Friday as a small background south swell lingers. Forerunners from a fresh long-period south-southwest swell are expected to arrive during the second half of Friday, bringing an upward trend with above-average surf this weekend. The latest guidance indicates that the swell will likely peak at advisory levels Saturday through Sunday, then ease through the first half of next week.
Surf along exposed north and west-facing shores will gradually lower and slowly shift out of the north-northeast over the next several days. Surf along east-facing shores will remain rough and choppy throughout the next few days due to fresh to strong trade winds.
