Swell Summary
A series of small, short to medium period west-northwest swells will bring small surf to north and west facing shores through the remainder 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 next west-northwest swell is expected to build Friday into the weekend. Additionally, a small, medium period north swell originating from Alaska Peninsula gap winds is expected to arrive tonight and continue into the weekend.
Rough and choppy surf will continue along south-facing shores due to the southerly wind direction. These south winds will intensify tonight into Friday, causing south shore surf to build Friday into the weekend, likely reaching advisory levels. Once southerly winds diminish early next week, a small to moderate, long-period south swell generated by a gale force low east-southeast of New Zealand will arrive along south-facing shores and build into midweek.
