Looking Ahead

Moderate to breezy trade winds into the weekend. Passing showers will be focused over windward and mauka areas. An increase in shower activity is expected this weekend and early next week due to increased low level moisture riding in on the trades.

Today

We expect partly to mostly cloudy skies with scattered showers for windward spots. Mostly clear morning for the Kona side with afternoon scattered showers and mostly cloudy skies. Winds are northeast from 10 to 20 mph with higher gusts. High temperatures from 80° to 86°.

UV index at 12 (“extreme” exposure level)

Tonight

Northeast winds tonight around 15 mph with higher gusts. Mostly cloudy skies with scattered showers for windward spots tonight. Skies should clear as the night goes on for lee areas. Low temperatures from 69° to 75°.
