Puna Weather
Saturday 20th December 2025
Mostly dry with light east or southeast winds today and Sunday.
Monday and Tuesday scattered showers with moderate to breezy east winds.
A massive high pressure system is to our north is driving easterly trade winds through Wednesday (surface animation). Winds start light today, increasing to moderate, and sometimes breezy by Tuesday.
A couple of bands of moisture sag south and over us both Monday and Tuesday (moisture anomaly animation). Showers from this moisture and the building trades favors night and early morning hours. A building high aloft (500mb animation) lowers our inversion through the period. This means we're likely to get better showers with the band of moisture Monday, than the one on Tuesday.
The east winds and moisture point towards rain, but the building high aloft should keep totals mostly light to moderate.
The high aloft is forecast to remain over the region, limiting rain through next weekend.
