Puna Weather
Monday 17th August 2026
Today very humid with periods of heavy rain and moderate easterly trade winds.
Tuesday and Wednesday less humid with scattered showers and light to moderate easterly trade winds.
Thursday through Sunday very humid with light winds and periods of heavy rain possible. VOG is also possible.
Departing Lala is still drawing tropical moisture over us today. Models show a break in the humidity for Tuesday and Wednesday as high pressure to our northeast dominates.
Far to our east is the remnants of Hernan. As it passes by our trade winds slacken and our humidity spikes again with dewpoints approaching 75F beginning Thursday.
The NHC is keeping an eye on an area of possible tropical development to our southeast. The European model has be showing low shear over this region for a couple of days and now the GFS is moving towards a similar solution with divergent flow over the same area Lala came from.
It is unusual to see so much activity near 135W, but high sea surface temperatures have put us at higher risk.
