The worst I've had is 47C a few years back, over 116F. Just moving your bare arm through the air made it feel like it was on fire. It makes these 40 degree days kind of normal. We usually have between 40 and 42 at some point in the summer.
My house takes a long time to warm up, it's about even with the outside now. Cool change is coming after 9pm. I don't mind the whole steamy effect, I usually enjoy it as long as there are no fires. I've never had air conditioning anywhere I've lived.
