Puna Weather
Saturday 4th April 2026
Today through Monday light winds and mostly dry with possible VOG.
Tuesday and Wednesday light to moderate south winds and humid with periods of rain, possibly heavy at times. VOG and thunder are also possible.
Thursday and Friday moderate to breezy south winds and humid with periods of rain, possibly heavy at times. VOG and thunder are also possible.
Next weekend light to moderate south winds and humid with periods of rain, possibly heavy at times. VOG and thunder are also possible.
Total rainfall over the next week or two will likely lead to flooding concerns islandwide.
Our trade winds are weakening as we get setup for another Kona low event. A series of lows drop into a jet stream trough to our northwest Monday through Friday. Each low pushes the upper level trough farther south and closer to us. The large scale pattern supports transporting deep tropical moisture over us from the south Tuesday through next weekend (mid-level moisture animation). Aloft the upper level trough brings colder air increasing instability. All in all look for a repeat of the previous Kona lows we've seen this winter, but the main rain band may be closer to us this time instead of focusing on Oahu. This is potentially a long lived event increasing the risk of flooding.
Sea surface temperatures over the tropics (SST chart) to our south and southwest are much higher than normal and this is fueling extra moisture over us and also a possible record breaking early season typhoon to our southwest (Pacific basin chart).
