I like it when it's hot. Too hot is much better than too cold. You get used to a little sweating, but you never get used to shivering.
In September 2010 I was in the USA, one of the places I visited is
Death Valley, one of the hottest places on Earth. Down in the valley at the salt planes, at the
Devil's Golf Course, it was over 40 C (104 F). It's very dry there, so it was nice and warm.
In a few weeks I'm going on holiday to Croatia. A friend of mine who is there now told me that it is 38 C (100 F) there.
