Puna Weather
Wednesday 8th April 2026
This afternoon through Thursday humid with light winds and occasional heavy showers and afternoon thundershowers. VOG is possible.
Friday stormy with gusty south winds and frequent heavy rain and thunderstorms. Widespread flooding is possible.
Saturday and Sunday humid with light winds and occasional heavy showers and afternoon thundershowers. VOG is possible.
The trough that brought heavy rain from Kau to Hilo is moving off to the northeast leaving light winds and abundant tropical moisture over us. The light winds will allow daytime heating to trigger afternoon convection Wednesday and Thursday.
Another trough approaches our island chain Thursdy and Friday maintaining southwester flow aloft and keeping deep tropical moisture over us. It also brings diverging flow in the upper atmosphere and converging flow near the surface. Latest model runs show winds below 5,000' from the east or southeast on Friday which would allow for widespread heavy rain. If the winds are instead from the south much of Hamakua would be in the rain shadow of our mountains.
