Puna Weather
Thursday 2nd July 2026
Today through early next week light to moderate easterly trade winds with widely scattered showers, mostly during the night and early morning hours.
A broad ridge to our north (surface animation) supports easterly trade flow over us for the foreseeable future. Upstream moisture is somewhat limited due to regional mid-level subsidence resulting in an inversion around 6,000' through much of the period. Nonetheless, sea surface temperatures surrounding our island are quite warm and because of this expect somewhat warm and humid conditions through much of this summer.
Far off to our east is Tropical Storm Douglas. Douglas is moving off to the north and will soon degrade into a remnant low over the cold waters of the northern Pacific. On the east side of the storm tropical moisture is being drawn into the circulation from the Intertropical Convergence Zone (satellite image). This moisture will likely be carried west by the background trade flow. Because of this... models show higher humidity and a risk of increased showers for us in around a week or so.
