This evening was a great round orange ball of sun settling (not setting) into a brassy greyish cloud cover/ pollution haze, and certainly stinking of same. That's the skyscape of heatwave that I know and can remember only too well. The problem is that it was 10C too cool for any kind of heatwave: the air which should have been a close unbreathing sweat-producing blanket was not unpleasantly cool. Just the humidity and the smell made it uncomfortable.
I may still sleep with the dry AC on anyway, rather than muggy air from the window fan. Have ativanned a frozen shoulder, so might as well make my sleep perfect.
