Swell Summary

An elevated east swell will keep surf heights in the High Surf Advisory range today along east facing shores. This east swell will gradually lower from tonight through Friday. Small surf will continue along north and west facing shores through Friday. Surf heights along east facing shores will quickly rise and may reach warning levels Saturday and Sunday due to a combination of strong trades returning over the Kauai and Oahu waters and the arrival of a medium period north swell. Surf could reach advisory levels for north facing shores during this time. This swell will slowly decline from Sunday night into Tuesday. A small background south to southwest swell will keep surf small along most south facing shores with a small bump expected on Thursday and Friday.
