Puna Weather
Tuesday 4th August 2026
Today through Friday light winds and humid with scattered showers and VOG possible.
Saturday and Sunday moderate easterly trade winds and very humid with scattered or numerous showers.
As Ex-Genevieve plows into the Pacific high they both weaken and so do our trade winds. The high rebuilds for a return of easterly flow this weekend. Also arriving from the east is a weak mid-level trough and associated pool of moisture. The trough could bring some instability, so some of the showers could be heavy and/or often.
The MJO report today says that models think it's time for the MJO to encourage tropical activity in our basin in a couple of weeks. I will make a point of keeping an eye on shear and mid-level moisture along with weak or divergent flow aloft as we enter the highest risk season for tropical cyclones.
