Swell Summary

A small northwest swell peaking this evening will be overwhelmed by a larger northwest tonight, with waves peaking around High Surf Advisory levels on Wednesday and Wednesday night as the swell shifts out of the north-northwest (330 degrees). The north-northwest swell will gradually decline Thursday and Friday, with another northwest swell pushing surf back near the advisory level Saturday.

East shore surf will be on the rise Wednesday and Thursday, primarily from increased short period trade wind swell, though the western end of the island chain could also experience a brief short period north (350-010 degrees) swell of 3 to 6 feet at 10 seconds. This north swell will be primarily aimed west of Kauai, but some wrapping energy could push east shores of Kauai near the High Surf Advisory level Wednesday. The north swell will rapidly fade on Thursday, when peaking trade wind swell will produce surf just below the advisory level on east shores of all islands. East shore surf will decline through the weekend as trades weaken over and upstream of the islands.

For south shores, tiny background south swell energy will persist.
