We expect high temperatures from 84° to 89°. Cooler northeast winds are expected from 10 – 20 mph. Partly cloudy skies are forecasted with scattered showers in the morning for windward areas. Leeward spots are expected to be sunny to start with building cloud cover and afternoon upslope showers.
UV index at 13 (“extreme” exposure level)
Partly cloudy skies are expected with scattered showers for windward spots. Leeward spots should be partly cloudy with isolated showers. Northeast winds are forecasted from 10 to 20 mph. Low temperatures from 71° to 76° are expected.
Breezy trades are expected through the weekend, with trades slowly diminishing early next week. A few showers can be expected to ride in on the trades from time to time, affecting mainly windward and mauka areas during the nights and mornings. It is still too soon to say if hurricane Hilda, located far to the southeast of Hawaii, will have any effect on our weather toward the middle of next week.
