Puna Weather
Monday 23rd February 2026
Today light winds with onshore breezes in the afternoon. VOG is possible through the day. Isolated morning showers with widely scattered afternoon showers and thunderstorms. Some of the showers could be heavy at times.
Tonight through the rest of the week moderate northeast trade winds with less VOG and scattered windward showers, mostly during the night and early morning hours.
An upper level low over us today (500mb chart) continues to interrupt our trade winds allowing for onshore flow during the afternoons. Winds at our mountain levels are from the northwest, placing windward locations on the drier side of our mountains. There is enough cold air aloft associated with this low to allow for afternoon convection, which could produce some heavier showers, but activity is expected to be mostly over our mountains.
The upper level low weakens and exits east allowing high pressure to build in to our north for a return of northeast trade winds (surface chart) beginning later today. The onshore flow will favor our typical pattern of windward showers for the next week or more.
