[citation][nom]chripuck[/nom]Where do you live that 40C is the norm in summertime? I live in Atlanta and 35 is average. Even South Florida doesn't really get much hotter.[/citation]
Well, lucky you, I'd say.
Southern California, which is very much a desert (ie a very hot and dry climate - hence all the fires every year here; arson heaven) gets well into the upper 40s quite frequently. Won't even mention Death Valley and probably others here that get to 50s... I don't have average for the full months where I am but I know many times it's been in mid-high 40s and my towns high is 47.
Of course, you have higher humidity and I would hate that too, but that is another story entirely.
