Looking Ahead

ARTICLE CONTINUES BELOW AD

Trade winds are forecast to pick up in strength to breezy levels today. On Friday they may weaken slightly. Clouds and showers are expected to focus over our usual windward and mauka spots until the winds weaken and shift out of the southeast and south. This is expected starting Saturday and through the weekend resulting in warmer, more humid weather with afternoon sea breezes and nighttime land breezes taking control of the forecast. Volcanic haze is also likely to spread over most of the state starting this weekend.

 

Today
