Swell Summary
A series of small, medium- to long-period west-northwest swells will bring small surf to north and west facing shores through the rest of the week. Kauai will block some of this swell energy from reaching Oahu and Maui, but it will make it into the west facing shores of the Big Island. The current swell will begin to diminish late Thursday before the next west-northwest swell builds Friday into the weekend. Additionally, a small, medium-period north swell is expected to arrive Thursday night and continue into the weekend.
Choppy surf along east-facing shores will continue to trend downward and remain below seasonal levels as south to southeast winds prevail. The southerly wind direction will contribute to rough and choppy surf along south-facing shores, but a bit of a lull can be expected on Thursday with a brief break in southerly winds before they reintensify Thursday night. South shore surf will build further Friday into the weekend, likely reaching advisory levels. Once southerly winds diminish early next week, a small to moderate, long-period south swell will arrive along south-facing shores.
