Swell Summary

Long period energy from an incoming north northwest swell has reached the northwest offshore buoys, as well as the nearshore buoy off of Hanalei, Kauai. This new swell will build surf to as high as double overhead over the more northwest-exposed reefs and coastlines through Saturday. North and west facing shore surf should peak below High Surf Advisory thresholds later today and Saturday. This first northwest swell of the young autumn season will begin to diminish late Saturday into Sunday. The next mentionable smaller west northwest swell will come from Tropical Cyclone Mindulle in the West Pacific and arrive next weekend.

South facing shore surf will hold at recent levels the next several days as small, background southwest south swell energy hangs on through the majority of next week.

Short period wind waves generated from fresh trade winds will support mainly small, choppy surf along many east facing shores.
