Swell Summary

A lingering north-northwest swell that peaked last night will continue its gradual decline through Saturday. On Sunday, surf along north and west facing shores will dip below average, then remain so well into next week. Guidance does depict a gale forming on Monday near the Kurils, then tracking northeast to the western Aleutians by Wednesday. If this materializes, Hawaii could experience an uptick in the northwest swell next weekend.

Surf along east facing shores will remain below the April average through most of next week due to the lack of consistent trade wind flow.

A small long period background south swell will move through this weekend, but will have little impact on surf heights. A larger pulse of long-period south- southwest swell is expected for the coming week.

Meanwhile, a passing upper level disturbance has triggered isolated to scattered thunderstorms across much of the state. The potential for strong thunderstorms will persist through tonight and possibly tomorrow.
