Puna Weather
Monday 25th May 2026
Today through Friday moderate to breezy east or northeast trade winds with widely scattered showers mostly during the night and early morning hours.
Saturday light to moderate easterly trade winds and humid with scattered showers.
Sunday through Monday light to moderate easterly trade winds and humid with frequent showers, possibly heavy at times.
A broad ridge to our north will maintain fairly dry easterly trade flow over us through Friday (surface animation). A trough passes by far to our north Saturday through Monday weakening our north Pacific high and in turn weakening our trade winds.
A little higher up, a mid-level low approaches from the west Saturday (500mb animation) through Monday bringing some cooler air aloft and a surge of tropical moisture nearer the surface. Sunday and Monday models show moderate low level convergence over us for additional lift. Although weakened, our trades are still likely to persist through this period of high moisture so frequent windward showers look likely. Some areas already have saturated ground, and this event could lead to local flooding at times.
A return to moderate easterly trades could keep enhanced windward showers lingering into next Tuesday or Wednesday.
Although low level trades persist through the period, above 8,000' winds are likely to be light at times, which could allow for VOG to spread over the island Saturday through Monday.
