Puna Weather
Friday 30th October 2026
Today light and variable winds and very humid with periods of heavy rain possible, especially this afternoon/evening. VOG is also possible.
Saturday moderate east or northeast trade winds with frequent windward showers and decreasing humidity.
Sunday through Wednesday noticably less humid with moderate east or northeast trade winds.
The mid/upper-level trough to our east weakens over the next couple of days shutting off the moisture from the tropics (200mb loop). High pressure rebuilds to our north this weekend for a return of trade winds (surface loop). Trade turn to more northerly early next week driving a moderate north swell towards our shores beginning Tuesday and lasting for several days.
Also early next week the GFS wants to spin up yet another tropical low to our southeast, same genesis region as Lala and Nolo. We'll have to wait until Monday or Tuesday for confirmation. That'll give time for a circulation to form and for models to settle on their handling of an upper level trough that swings through the Pacific north and (possibly) weakens the subtropical ridge allowing the storm to gain latitude. Too many unknowns at this point but timing points to a closest approach in a week or so. Keep an eye on this one.
