Puna Weather
Thursday 26th February 2026
Today mostly dry with moderate easterly trade winds becoming light later in the day.
Friday continued mostly dry with light winds.
Saturday through Monday widely scattered showers mostly over our higher terrain. Showers could be briefly heavy. Risk of VOG.
Tuesday and Wednesday moderate to breezy easterly trade winds with scattered windward showers, most frequent during the night and early morning hours.
A weak jet stream trough is northwest of us this weekend (200mb chart). As the trough moves east, it weakens our trade winds Friday through Monday (surface chart). A front associated with this trough stalls near Oahu, placing us in southwest flow aloft for high clouds, but not much rain. The light winds could allow for VOG to spread over much of our island.
Trade winds are likely to return late Monday or early Tuesday, pushing VOG to the west. Models show these trade winds lasting for a week or so bringing a typical windward rain pattern.
