Puna Weather
Friday 21st August 2026
Today and Saturday humid with light to moderate northeast trade winds and widely scattered showers.
Sunday humid with breezy northeast trade winds, likely stronger along our coast and over our higher terrain. Rain could be heavy at times, and some flooding is possible.
Monday humid with light to moderate southeast winds and scattered showers, possibly briefly heavy at times.
Tuesday and Wednesday humid with light to moderate easterly trade winds and widely scattered showers.
There is currently tropical moisture overhead associated with a weak trough passing by to our north. As the trough exits to the west we see moisture from Tropical Depression 2 approach from the east keeping it humid all the way through to Tuesday or Wednesday.
Tropical Depression 2 currently has its convection sheared off to the northwest by southeast mid-level winds between 500mb and 300mb. The GFS shows this shear persisting and keeping the storm from strengthening significantly over the next couple of days. As such its effects on us are likely to be an increase our trade winds and periods of heavy rain along with high humidity. The wind is from the northeast on Sunday which might help some with the humidity, but turns to southeast on Monday for warmer temperatures, lighter winds, and higher humidiy.
Trades return to normal late Monday, but the moisture takes and extra couple of days to clear the area. Hopefully we're looking at lower humidity on Wednesday or Thursday.
The MJO's departing shot is a possible storm forming this weekend in the eastern Pacific near Baja California. If this storm forms, it would likely pass by us around September 1st.
