Swell Summary
Large, rough surf along south-facing shores that has been observed over the past few days will trend lower tonight and Monday as wind speeds subside. A new long-period south swell will arrive late Monday night and Tuesday, giving an extended boost to south shore surf through late this week.
A moderate sized, short-period west-northwest swell will continue to affect north and west facing shores through Monday, but surf will remain below advisory levels. The one exception is for west facing shores of the Big Island, where a High Surf Advisory remains in effect through 6 AM HST. This 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.
