Looking Ahead

Trade winds will hold through the day Thursday, then slowly weaken and shift out of the south for the holiday weekend and into early next week. This means muggy conditions are forecast to return to the state. Clouds and showers will favor windward areas through Thursday, then become focused over leeward and interior spots Friday through early next week, especially through the afternoon and early evening periods. Warm and muggy conditions will likely continue through much of next week.

Today

We expect northeast winds around 10 to 20 mph. High temperatures are forecast from 84° to 89°. Partly to mostly cloudy skies with scattered showers for windward spots. Sunny for the Kona side with just isolated afternoon showers.

UV index at 12 (“extreme” exposure level)

Tonight 

Northeast winds are forecast up to 10 to 20 mph. Partly to mostly cloudy skies with scattered windward showers, isolated showers for lee spots. Low temperatures from 72° to 77°.
