Puna Weather
Thursday 5th November 2026
Today through Thursday moderate east or northeast trade winds with scattered windward showers mostly during the night and early morning hours.
Thursday night through early Saturday very humid with breezy northeast winds and frequent showers, possibly heavy at times. There is some risk of thunder and flooding.
Saturday and Sunday less humid with moderate easterly trade winds and scattered windward showers.
Ridging to our north keeps trades over us for the foreseeable future (surface loop).
Late Thursday through early Saturday a tropical wave passes by to our south (moisture loop). This feature tightens the pressure gradient over us for breezy winds which will enhance windward showers. There's plenty of moisture with dew points in the lower 70s and PW over 2". As far as dynamics go the GFS is showing pretty good low level convergence around our island Thursday night (skew-t) and on Friday there's some cooler air aloft. Either could trigger heavier rain and thunder.
Once the tropical wave passes by (Saturday) we should return to more typical trade wind weather with less humidity for much of next week.
