Puna Weather
Thursday 25th June 2026
Today through Sunday widely scattered showers, mostly during the night and early morning hours.
Monday humid with scattered showers.
Tuesday very humid with numerous showers, possibly heavy at times.
Wednesday decreasing humidity and showers through the day.
Thursday and Friday typical scattered windward showers, mostly during the night and early morning hours.
Moderate to breezy easterly trade winds through the entire forecast period.
A broad ridge of high pressure to our north maintains easterly trade flow over us for the next week or so. Far to our east is a weak low (1st chart) that will weaken due in large part to mid-level dry air (2nd chart) as it gets carried west in the background trade flow. Moisture from this low arrives on our shores beginning around Monday (3rd chart). The GFS is showing the deepest moisture over us around Tuesday while maintaining the low level trade winds. This is a recipe for heavier windward showers. The moisture exits to our west with drier air arriving around Wednesday.
