Puna Weather
Wednesday 5th August 2026
Today through Friday warm and humid with little or no wind and only widely scattered showers. VOG is possible.
Saturday moderate easterly trade winds. The day starts our warm and humid with humidity and showers increasing through the day.
Saturday night through early Monday moderate easterly trade winds, veryhumid with periods of heavy rain and possible thunder.
As ex-Genevieve plows into our northeast Pacific high, it interrupts our trade winds, leaving us with warm and humid and no wind for relief through Friday.
The Pacific high rebuilds and our easterly trade winds return this weekend. Riding in on the returning trades is a large area of tropical moisture with dew points in the mid-70s and moisture all the way up to our mountain tops (moisture animation). Convective potential looks sufficient for some thunder too, at least late Saturday and Sunday.
Both the GFS and the ECMWF model ensembles show the potential for tropical development to our southeast in a week or so. While both models keep shear in place over our island, offering a degree of protection... both models also show a moistening of the mid-level environment around our latitude (mid-level moisture animation), creating an environment more conducive for tropical cyclones. This bears watching.
