Puna Weather
Friday 10th April 2026
Increasing rain today with periods of heavy rain and possible thunderstorms tonight. Humid with moderate to breezy south winds.
Saturday decreasing rain through the day with decreasing south winds too. Continued humid.
Sunday and Monday light winds with periods of heavy rain possible, especially during the afternoons.
VOG is possible through the period due to the south or light winds.
A front is currently bringing heavy rain to Oahu and is moving towards the east. The GFS shows some moderation of the front before it reaches the windward side of our island, bringing more moderate rainfall today and tonight. The European model is much more robust with 6 to 12 hours of very heavy rain over us late tonight into early Saturday. Both models show convergent flow at the surface, but the GFS moves the divergent flow in the upper levels off to the north before the front reaches us. If the GFS is right expect another inch or 2 by Saturday morning. If the ECMWF is right, it looks more like 4 inchs to a foot in some places.
The upper level activity that is supporting this active weather moves off to the northeast on Saturday with less frequent rain after that. Nonetheless deep moisture remains in place with precitable water values near 2" for the foreseeable future.
