Long-period energy from an incoming swell from the northwest from the northwest reached the buoys off the northwest, as well as the coastal buoy off Hanalei, Kauai. This new swell will create waves of up to double over the reefs and coasts most exposed to the northwest until Saturday. Waves to the north and west are expected to peak below high wave advisory thresholds later today and Saturday. This first northwest swell of the young fall season will begin to abate late Saturday through Sunday. The next smaller west-northwest swell will come from Tropical Cyclone Mindulle in the western Pacific and arrive next weekend.

Waves off the south coast will hold at recent levels over the next few days as the south-southwest background swell energy continues through most of next week.

Short-lived wind waves generated by the cool trade winds will mainly support small choppy waves along many east trending coasts.
