My uncle talked about the hottest summer he could remember was 1934. It was 113 degrees in Galliopolis, Ohio and they didn’t have air conditioning.
My step-grandfather died in ‘02 at 92, we asked him one time what it was like back then. He said it started getting up into the 90’s by April, by July it ran over 110 for almost a month. The highest he could recall was 115.
They of course had no AC, he said they’d sleep outside on picnic tables with screen over them for the mosquitoes. You’d get up at light and work till maybe mid-morning, then sit in the shade or hit the swimming hole till evening and work till close to dark. He said it was awful.
Funny part is he said the winters then were butt spanking cold and ‘snow to the top of the fenceposts.’
