Swell Summary

Surf will remain below advisory levels along all shores through Friday morning with the continued passage of smaller, moderate period northwest swells. Larger, longer period northwest swells are currently being generated by a storm force low off to the distant northwest. Faster, longer period front running swells are expected to arrive from this system in Kauai and maybe Oahu through the day Friday and into the evening hours. This will build surf along Kauai and Oahu's northern and western exposed shores to surf advisory levels during the later half of the day. Peak surf heights on Saturday may approach High Surf Warning levels along north and west-facing shorelines. This swell will quickly fade from Sunday into Monday.

Trade winds will begin to deliver relatively small, short period choppy wind waves onto east-facing coasts Friday. An increase in surf heights is expected through the weekend as trade winds further strengthen near and upstream of the islands. As a result of this higher trade wind wave swell, a High Surf Advisory for east-facing shores may be required and commence as early as Saturday. Small, long period background south southwest swells will provide a slight uptick to early week south-facing shore surf.
