What’s Hawaii’s Weather Like in June?

Peter –
You are absolutely spot-on regarding Hawaii’s evening/night temps.
Comparing Southern California, or U.S. desert-Southwest evenings, which I used to believe were the best of the best – NO comparison. Hawaii wins hands down.
Then there’s what I call the rule of 85/65.
When the temps reach no more than 85-degrees, and the humidity no more than 65-percent, it really is like heaven on Earth.
In fact, probably more than anywhere else in the U.S., Hawaii’s weather is influenced more by from where the wind blows than by what the temps are.
Give us trade-winds, breezes with an easterly component (northeast being the best of the best) then you know your day is going to be sublime.
Turn those winds around, however (blowing from the south/southeast), and they become Kona breezes, generally winds from the sea, and humidity rises, which can make a day feel downright uncomfortable, and as a surfer, you know, makes the waves collapse upon themselves,
More rarely we get northern winds, which in wintertime can even add a chill to the air, making Hawaii feel “frigid” (wind chills down into the low-and-mid-60’s at night) by local standards.
Even less frequent are westerly winds, the rarest of all, blowing directly in from the ocean, causing stormy seas and, sometimes, even causing structural damage, much as winter (through westerlies can blow any time of year) storms do on the mainland.
And, finally you’re right, island mists are a precipitation wonder, and many local songs have been written about this phenomenon.
As always, Peter, wishing you fair winds and sublime sunshine!
