Swell Summary
A reinforcing bump in north shore surf is expected early Saturday as a small short to medium period north swell (350-360 degrees) fills into the region. However, the next significant north swell (350 degree) that could produce advisory-level surf along north- facing shores is scheduled to arrive Sunday night or early Monday. This swell will likely peak Monday night and then slowly decline through the rest of next week.
A small medium to long period south swell will maintain near waist high surf along south-facing shores for the next couple of days. Surf along west-facing shores will remain elevated as these shores will continue to be influenced by both north and south swell wrap. East-facing shore wind wave chop will remain relatively small under this weaker trade wind regime.
