Puna Weather
Saturday 24th October 2026
Today through Sunday light winds and a bit more humid but only widely scattered showers with VOG possible.
Monday and Tuesday humid with light winds and frequent showers, possibly heavy at times. VOG is also possible.
Wednesday and Thursday very humid with light winds and rain and thunder. Rain likely heavy at times with some flooding possible. VOG is also possible.
Friday and Saturday a trend towards less humidity with frequent windward showers on Friday decreasing to scattered on Saturday. Moderate easterly trade winds both days.
Next week a mid/upper level trough approaches from the northwest. As it deepens between the Dateline and our island chain tropical moisture is drawn northeast and over Hawaii island Monday through Friday. The trough is closest on Wednesday and Thursday for some cooling of our atmosphere at higher altitudes. Very warm and humid conditions nearer the surface create a steep temperature gradient for unstable conditions and the risk of heavy thunderstorms both Wednesday and Thursday.
The mid/upper level trough to our west weakens Friday/Saturday as high pressure builds near the surface to our northeast for a return of easterly trade winds. With a good amount of moiture remaining over the region expect windward showers possibly into Saturday.
