Puna Weather
Monday 23rd March 2026
Today and tonight light to moderate northeast trade winds with frequent showers, possibly heavy at times. Isolated thunderstorms are possible this afternoon.
Tuesday light to moderate northeast trade winds with decreasing showers through the day, possibly increasing again at night.
Wednesday through Friday light to moderate northeast trade winds with widely scattered showers, mostly during the night and early morning hours.
While rainfall has been lacking over windward Hawaii island during this Kona low event, there is still abundant tropical moisture in place over our entire region. Surface flow has already turned from southwest to northeast which will now focus rainfall on our side of the island.
There is some low level convergence with winds from the west and winds from the east meeting over us. Aloft the main trough still hasn't passed by (500mb chart) and as such we continue to have cold air aloft... so we have another day where heavy rains are possible, even some isolated thunder.
The mid-level trough is off to our east by later Tuesday, placing us in increasingly dry northerly flow aloft. As high pressure reasserts itself over the northeast Pacific we're looking at a typical trade wind pattern Wednesday through Friday.
The latest MJO report comes out later today, so I'll discuss the tropics in tomorrow's post.
