Puna Weather
Sunday 29th June 2025
All week light east or southeast trade winds with widely scattered showers, favoring south and southeast facing shores and slopes.
Heading into next weekend trade winds increase to moderate and sometimes breezy from the east. Upstream moisture looks limited so expect only widely scattered showers despite the increase in winds.
Winds should keep most windward areas free of VOG throughout the forecast period.
A trough aloft to our northwest has acted to weaken our trade winds and will continue to do so for most of the week. Models show this feature weakening and lifting off to the northeast as we head into the weekend. This will allow a ridge to build in from the east, bringing regional subsidence for dry conditions and an increase trade winds.
Tropical storm Flossie (NHC graphic) is off the coast of Mexico and forecast to become a hurricane for a while before heading north into the great Pacific hurricane graveyard. The next two systems are forecast to take paths farther to the south and eventually the moisture from some of the activity will reach us, but that's two weeks away and until then enjoy the low humidity.
