Looking Ahead

As a front approaches, trade winds are expected to 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 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. Volcanic haze will also be a problem for some areas.

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 with clearing in the afternoon. Sunny for the Kona side in the morning with building clouds in the afternoon and isolated afternoon showers.

UV index at 12 (“extreme” exposure level)

Tonight 

Northeast winds are forecast up to 10 to 20 mph with light and variable conditions starting to take hold. Showers for interior and leeward areas in the evening and clearing as the land breeze takes hold. Low temperatures from 72° to 77°.
