The official start of summer is still just a little more than a week away, but our summer-like trade wind conditions will continue through Friday, with light to moderate east-northeast winds at around 10 to 15 miles per hour. Daytime highs will hover around the 90-degree mark for many areas, and we’re not expecting much in the way of showers, except for the usual light nighttime and morning showers for windward and mauka areas.
A weak disturbance is forecast to pass south of the state and will increase showers for Maui and the Big Island from Friday night through Saturday night. The rest of the islands might see a few more clouds and showers as well. The trade winds will pick up and become locally breezy statewide as the trough passes.
Surf is going to be heading upward for south-facing shores Thursday night with the arrival of a long-period south-southwest swell. Be on the lookout for a high surf advisory to be posted Friday. This swell is expected to peak Friday afternoon before declining Saturday. There’s also a pair of small northwest swells that will bring head-high sets Friday into the weekend.
