Breezy trade winds will continue into Wednesday. Low clouds and showers will favor windward and mauka areas. A cold front will approach Kauai from the northwest and cause our winds to weaken and veer from the southeast on Thursday and Friday. Sea breeze convergence could trigger cloud build ups and locally heavy afternoon showers across island interiors during that time. Locally breezy northeasterly trade winds will fill in after the front moves across the island chain this weekend.
We expect mostly cloudy skies with numerous windward showers in the morning and scattered showers in the afternoon. The Kona side will be mostly sunny with scattered showers in the afternoon as clouds build. Hazy areas are expected. East winds are forecast from 15 to 20 mph. High temperatures from 81° to 86°.
UV index at 12 (“extreme” exposure level)
East winds are expected around 10 – 20 mph. Mostly cloudy skies are forecast with scattered windward showers. For the Kona side mostly cloudy to start with clearing skies as the night goes on. Low temperatures from 70° to 75°.
