Hmm, here in my country, we experience temperatures as much as 38 degrees Celsius or 100.4 degrees Fahrenheit. Well, thats according to my thermometer. But the weatherman says that it's as much as 40 degrees Celsius in some parts.
I don't usually turn on my AC. I'm adapted to high temperatures. But if it's too much for me to handle then I will turn it on, but only for an hour or two since electricity isn't cheap.
