    Looking Ahead

    Afternoon sea breeze conditions are forecast to bring pop up scattered showers over interior and leeward areas into the evening. Some could be locally heavy from time to time through Wednesday. At night, land breezes will clear out most clouds and showers. The trade winds are expected back Thursday and should last into the weekend.




    We expect light and variable winds up to 10 mph with afternoon sea breezes developing. Mostly sunny skies in the morning with clouds building in the afternoon for lee and interior areas and numerous showers, some of those will be heavy downpours. Partly cloudy skies for windward spots with scattered showers. Temperatures up to 84° to 89° and feeling warmer due to the higher heat index. Hazy skies are expected.

    UV index at 11 (“extreme” exposure level)



    Light and variable winds up to 10 mph with a land breeze developing at night. Clouds and showers in the evening are expected to clear as the night goes on. Low temperatures from 69° to 74°.
