Forecast: Huge waves, light winds for the weekend

First Alert Forecast for Saturday

A huge northwest swell will bring dangerous surf for most shores over the weekend. A high surf warning has been issued from 6 a.m. Saturday through 6 p.m. Sunday for the north and west shores of Niihau, Kauai, Oahu and Molokai, the north shores of Maui and the west shores of the Big Island. Waves of 25 to 35 feet are possible for the smaller islands. There’s also a small craft advisory up for most Hawaiian coastal waters due to the swell.

The light wind weather pattern won’t be changing for several more days. The background flow is from the east-southeast, but the weak winds will allow for afternoon sea breezes and overnight land breezes, which could result in pop-up showers late in the day with clearing and cooler temperatures at night. The atmosphere is also stable, so rainfall should be light and isolated. A front could move through the islands late Thursday and Friday, bringing southwest Kona winds and a few showers. Breezy north to northeast winds could follow the front on Friday.
