Strong southerly winds will keep large and rough surf in place along south facing shores today, with the surf then trending lower tonight and Monday. A new long period south swell will arrive late Monday night and Tuesday, giving a nice and extended boost to south shore surf through late next week.

A moderate sized short-period west swell associated with the kona storm will affect north and west facing shores during the next couple days, but surf will remain below advisory levels. The one exception is over west facing shores of the Big Island, where advisory level surf is expected today. As a result, a High Surf Advisory has been issued for west facing shores of the Big Island through 6 pm this evening. The short-period swell will lower Monday night and Tuesday, while a new medium-period north- northwest swell fills in. This north- northwest swell could bring surf up to advisory levels Tuesday night and Wednesday, with the swell then shifting more northerly and lowering below advisory levels Thursday into next weekend.

Surf along east facing shores will remain well below normal levels through the middle of the week, before trending upward Thursday into next weekend as trade winds return over and upstream of the islands.
