Puna Weather
Sunday 16th August 2026
Today hot and humid with south winds that are sometimes gusty and periods of heavy rain.
Monday winds turn from southeast to east through the day as humidity slowly decreases. Scattered showers.
Tuesday and Wednesday are the best days with moderate trade winds from the east, lower humidity, and only widely scattered showers.
Thursday through next weekend hot and humid with light winds and the risk of VOG.
Lala is departing to our west which places us in southerly flow bringing more tropical moisture to our island today.
High pressure to our northeast dominates late Monday through early Thursday bringing a return of more typical easterly trade winds and lower humidity.
Thursday we see the remnant moisture from Tropical Storm Hernan bring another round of high humidity.
The NHC has flagged an area to our southeast for potential development over the next week. The latest GFS run forecasts significant vertical shear in this region at that time, making development more difficult. The latest Euro model does not show this shear. Mid-level air between this region and our island is not forecast to be as dry as it was when Lala approached. Once again, we're watching the tropics.
