Swell Summary
Small, short- to medium-period north-northwest swell energy will decline through Thursday. The next small north-northwest swell will move into the Hawaii region on Saturday, increasing surf heights along north- and west-facing shores through the weekend.
A series of small, long-period south swells will support near- average surf along south-facing shores over the next several days. Meanwhile, strengthening trades maintain elevated surf along east- facing shores into next week.
