I can't really complain. It's been a quite decent summer.
But the current spell of ~ 94° highs in the humidity of the Piedmont of SC is a bit trying. In a normal summer, we would have been subjected to weeks and weeks of this, so really I'm not complaining.
Oddly, the temperature spread for the highs from the mountains of western NC to the Piedmont has widened to 10° for the next few days, several degrees beyond the "normal" 6 or so.
We never turned on the AC (a mini-split upstairs) in the mountains this summer, and were OK even on the hottest days (hmm, 80°F on the main floor was a bit much in the afternoon, not to mention upstairs in our loft bedroom, but we managed -- and it cooled off at night just fine. We keep the AC set on 77°F in the Piedmont, so it's not so different, I suppose.
My major concern is the humidity -- and the mildew considerations that come along with that, without "conditioned" air! But that's part of living in a warm and humid climate, too.
It's also lovely to hear the nocturnal symphony and early morning bird songs, too, when the windows are open at night.
