Looking Ahead

Southerly winds will strengthen Tuesday, pulling tropical moisture with increased humidity and thickening high clouds over the islands. Bands of showers, some heavy, will be focused over Kauai and surrounding waters on Tuesday into Wednesday, though a few bands of showers may affect Oahu at times. On Maui County and the Big Island, a continued land and sea breeze pattern will produce afternoon clouds with spotty showers. Trade winds will gradually build on Thursday and Friday.

Today 

We expect southeast winds up to 15 mph with local land and sea breeze conditions. Partly to mostly cloudy skies are forecast with isolated showers mainly in the afternoon and scattered showers mainly for the Puna and Kau districts. Hazy skies are expected. Temperatures up to 82° to 87° and feeling warmer due to the high heat index.

UV index at 7 (“high” exposure level)

Tonight 

Partly to mostly cloudy skies with isolated showers. Low temperatures from 73° to 78°. Winds are expected to be variable up to 15 mph.
