Puna Weather
Sunday 8th February 2026
Today through Monday rain heavy at times with some flooding. Moderate northeast winds becoming breezy and as they turn to the east late tonight. Isolated thunder is possible both days.
Tuesday through Friday moderate to breezy easterly trade winds with widely scattered showers during the day increasing to scattered and briefly heavy at times during the night and early morning hours.
An upper level low to our west is pumping deep tropical moisture over us from the southwest (satellite animation). Surface winds have turned from southerly to northeast and that has shifted the heaviest rains from our south facing exposures to our Hamakua coast (radar animation) where we have a report of thunder and 5" of rain in an hour.
A surface high to our north will continue to drive onshore winds bringing the heavy rains to all windward locations today... except for Kau, because they are sheltered somewhat from the northeast flow. As the high moves towards the east, our winds become easterly (surface chart) continuing the risk of heavy rain, this direction should include Kau in the rains.
Moisture decreases on Tuesday, but onshore winds continue all week for more typical trade wind showers.
