Puna Weather
Thursday 9th October 2025
Today light southeast winds. A little bit humid with some widely scattered showers. South facing shores and slopes could get some heavier showers at times.
Friday through most of Sunday light to moderate easterly winds with decreasing humidity and widely scattered showers, mostly during the night and early morning hours.
Late Sunday into Tuesday periods of rain, possibly heavy at times. Winds light to moderate from the east. Isolated thunder is possible Monday and Tuesday.
A departing upper level low to our north is continuing to support southerly flow over the region. This flow is pulling some higher humidity over our island for the next day.
As the upper level low continues to depart to the northeast, a surface ridge forms to our north supporting easterly trade flow through much of next week (surface animation). Embedded within the returning trade flow is an area of enhanced moisture along with some low level instability (satellite image). This feature is due to arrive on our windward shores sometime late Sunday.
Additionally... a new upper level trough dives south Sunday/Monday, this time closer to our island (500mb anomaly animation). This feature brings colder air aloft, creating unstable conditions. Moisture is forecast to extend to well above our mountain tops.
The freezing level looks drops to around 16,000', which isn't low enough for snow on our peaks.
