*scoffs*
[oblig weather report] "Normal" temperature range here now is 30 to 40°C, often about 5 degrees higher, with daytime humidity usually around 60%, higher at night. It was 35°C at midnight one day last week.
Yes, of course we use airconditioners, to bring the inside temperature down to somewhere in the mid to high 20s, and to dry out the air, and to avoid situations like the one on Wednesday night when (presumably) the freezer electrics overheating in the grocery store below our flat caused a fire that almost burnt down the building. I'm not surprised it happened, because they've never bothered to kept the shop cool enough. They're paying for it now.
During the heatwave in Bris at the start of last year, I found my "can't really sleep" point was almost exactly 23°C. Even one degree lower helps.
I don't know how I'm going to cope with Tasmania in early August.
