I grew up in Florida without A/C so am adapted, I looked and this would be a balmy spring day here, not hot at all, but WTF? If you live where it's usually cool why isn't everyone adapted to that?
I still get too hot here when it's 38C but know how to sit still with the fans on, on the porch, can be comfortable. Still would not prefer it. About 27-30 outside is great, and for a beach day a little hotter so that it feels good to get in the water.
A/C in the house set to 78f so that is 26, and comfortable, it's low enough to remove the humidity and keep mildew out.


That's our winter temperature, I would be putting on a sweater at 17!
And yeah I'm sure it's mostly that we become adapted to where we grow up. It IS hotter here than it used to be, too. Not so much the winters, which have often (not always) been mild historically and the cold snaps are sometimes colder than they used to be too. Double-tap freeze this year killed my newly planted garden. Yuck.
