Puna Weather
Wednesday 25th February 2026
Today moderate northeast trade winds with scattered showers decreasing through the morning.
Thursday and Friday light to moderate easterly trade winds with isolated showers during the day increasing to widely scattered during the night and early morning hours.
Saturday and Sunday light southeast winds and widely scattered showers.
The jet stream has a ridge over us through Friday (200mb chart). Subsidence under this ridge helps to keep our inversion low, around 5,000', for only a few showers.
This weekend a mid-level low brings moisture southwest flow aloft and the risk of heavy rains to Kauai and Oahu, but current forecasts only show high clouds for us (mid-level moisture chart). This feature also weakens our trade winds for the risk of VOG.
High pressure is forecast to dominate the northeast Pacific beginning sometime early next week (surface chart) for a return of easterly trade winds pushing VOG off to the west and the return of scattered windward showers.
