Swell Summary

Surf along north facing shores will remain small for the remainder of the afternoon before a moderate, medium period north-northeast (010-030 degrees) swell fills in this evening. This swell will peak Christmas Day near High Surf Advisory levels, before declining Friday. This swell has been filling in at the offshore buoys through the day with most of the energy to be focused over the eastern end of the state when it arrives. A Marine Weather Statement is in place for moderate harbor surges at Kahului and Hilo tonight through Christmas Day. A combination of the declining north northeast swell and a small long period west northwest swell will keep small surf through the weekend. West facing shores will see a tiny, moderate period west swell hold through the day. The next large long period northwest swell is expected over the first half of next week but stay tuned as the system develops northwest of the islands.

Rough and choppy surf along east facing shores will remain elevated tonight before gradually declining as trade winds ease slightly tonight. With the building north-northeast swell expected this evening, exposed shorelines will see wrapping energy through Friday. Surf along south facing shores will remain very small through the week.
