On days like this when the trade winds aren’t blowing, they’re replaced instead by Kona breezes, which blows in the opposite direction, generally.

Thus, they bring volcanic fog (or vog) over from the Big Island, blanketing the area in a light haze. What is typically a clear view of the summit of Haleakala Volcano from anywhere on Maui’s central plain becomes a misty obscuration. Is that even a word? Maybe obscurement; yes, I like that better. :-)

The fog also makes my allergies act up a bit; people suffering from bronchial ailments or asthma, also have a hard time of it (I imagine the folks who live on the Kona side of the Big Island, especially).
