Leeward spots across the Big Island should get lots of morning sunshine. As the land heats up, sea breezes are expected to develop which will lead to afternoon cloud cover and possible isolated showers. Hazy skies are expected in the afternoon for parts of the Big Island (see UHSOEST vog model above). High temperatures should fall in the range of 77° to 82°.

Winds are expected to weaken on Thursday. Light southeast flow will then prevail into the weekend resulting in land and sea breezes over the islands and periods of vog and haze. A very gradual increase in moisture is expected towards the end of the week. The weekend will bring light east to southeast flow which will result in local land and sea breezes, and a few more showers. Temperatures will also gradually warm through the rest of the week.
