Puna Weather
Saturday 7th February 2026
Today light south winds with widely scattered showers, mostly south of Hilo.
Sunday light northeast winds increasing through the day, becoming strong at times overnight. Scattered showers in the morning with numerous and sometimes heavy rain overnight.
Monday strong east trade winds through the day with bands of heavy wind driven rain. Everyone should get a good soaking.
Tuesday strong east trade winds with scattered showers.
A front to our northwest will stall over Maui today, keeping light south winds over our island. Behind the front is strong high pressure which drives increasing northeast winds towards our shores through Sunday. Late Sunday and Monday the flow over us comes out of the east and accelerates due in part to a low level trough to our southwest. The high continues to drive east trade winds over us into Tuesday.
Sunday and Monday an upper level low to our west (500mb chart) brings colder air aloft creating some instability over the entire island chain. It also draws deep tropical moisture up from the southwest (mid-level moisture chart).
The combination of moist air, strong trade winds, and some instability will bring heavy rains to our windwards shores. The peak looks to be late Sunday into early Monday.
