Climate of USA

I am very interested what kinds of climate are there in America? Which cities are warm and which cities ones are cold? How many degrees cold are they in winter in degrees?

In my opinion, only Los Angeles and San Diego are temperate enough for me.  Not too hot in summer nor too cold in winter.  The heat and cold are dry.  However, if you want snow, just drive up to the nearby mountains.  One can have a suntan on the beach in December while skiing up in the mountains.  As for other cities, they are either too hot and humid or too cold and wet for me.
