Sleeping temperatures began their return last night, though it was very early morning before my room was feeling the difference.
I daresay (oh yes, I do) we won't have to run any air conditioners this week. And isn't that lovely.
I don’t know what it means to not run the AC.
I have a vague memory of not doing so during my years living in Oakland CA.
Many a summer morning I wore a jacket until things warmed up and the fog lifted.
However, around 1996 or so, summer weather began changing. It changed sufficiently for me to go to Sears and buy an A/C for my living room window.
I also had a double fan in my bedroom window (one fan blowing in and one blowing out).
By 2010, I had bought two portable A/C units, one for living room and one for bedroom. There was no "not" running them, either. The Bay Area can get rather hot at sea level. The nights do cool down, but the heat remains in your domicile unless you cool it down.
It gets nowhere near as hot as South Carolina in August, but even here we adjust when the heat is omnipresent. When I was growing up in this small town, we had only fans, and my family had ONE fan that was kept in the living room. Windows were always open, and even though they were screened, mosquitoes (skeeters, as we called them) feasted on my young legs and arms. I don't see skeeters much any more...one or two linger around doorways, but they usually are too lazy to try to bite me.
