Puna Weather
Sunday 15th March 2026
Today very humid with light winds most areas except for slopes exposed to the southwest (Kau and northern Hamakua) where strong gusty winds will slowly decrease through the day. Scattered showers, possibly heavy at times.
Monday very humid with light winds and scattered showers, possibly heavy at times.
Tuesday and Wednesday very humid with light winds and numerous showers, heavy at times.
The Kona low that brought damaging winds and rainfall statewide is slowly weakening and moving away to the northeast (satellite loop) allowing winds to begin to relax. In the mean time the lower level winds have turned to more of a southwest direction, and now the mountains are protecting most of the windward side.
Although the low exits, the deep moisture remains in place keeping elevated dew points and the risk of heavy showers. Low level winds turn briefly to the northeast on Tuesday and Wednesday as an upper level trough passes by to our north (200mb). Some enhancement from the passing trough the favorable wind direction add up to more showers for the more typical trade wind shower locations.
Light winds through the period mean VOG could become widespread.
Some mid-level dry air is forecast to work its way into the region towards the end of the week, but models are showing another low forming to our west next weekend placing us in southerly flow again, and pulling more deep tropical moisture overhead. All in all models show very humid conditions and another foot of rain over the next couple of weeks (total rainfall chart).
