Puna Weather
Thursday 2nd April 2026
Today through Sunday light to moderate northeast winds and mostly dry. Chilly nights.
Monday and Tuesday light winds with VOG possibly, continued mostly dry.
Beginning next Thursday and lasting for several days... south winds, possibly strong at times, and very humid with periods of heavy rain and thunder possible.
A low forms off the northern California coast this weekend pushing the high that drives our trade winds into the far northern Pacific and cutting off our trade winds.
Another low forms in a north-south oriented trough over us beginning around Wednesday. With high pressure to the west and east of this trough, deep tropical moisture is pulled north and over us. Colder air aloft associated with the trough will create some instability, possibly leading to thunderstorms.
The MJO has broken into two signals, one now over Africa and the other hung up over the central Pacific. This is likely to enhance the surge of tropical moisture we are forecast to receieve later next week, as the latest MJO report states that a stationary signal over the central Pacific is linked to the previous Kona Low activity over Hawaii. It is also contributing to the formation of a possible cyclone west of the dateline. If this storm forms it will be farther east and early in the season than we have records for.
