Swell Summary

A new large north to north-northeast swell will rapidly fill in from northwest to southeast down the island chain today and tonight, hold through the remainder of the weekend, then slowly lower early next week. A moderate northwest swell will move through the islands Wednesday through late next week. An east swell will gradually lower through the weekend as trade winds upstream of the islands diminish. A more typical short-period trade wind swell will return during the middle to latter part of next week as trade winds over and upstream of the islands increase. Surf along south facing shores will receive a small boost today as a small southwest swell moves through the islands. South shore surf will then fall back to background levels Sunday through late next week.
