The temperatures you get there are crazy, folks!
I am not sure, I could bear them, the hottest temperatures I've ever experienced here in Germany must have been around 40, and this almost killed me. You can do something against cold weather, dress up, put on the heating, but there is simply no way to escape those high temperatures (well, if you have air conditioniong, maybe, I don't).
I simply associate Christmas with cold temperatures and snow - your crazy upside-down weather!
