Not only do I not see those extremes, it didn't even snow last winter for me, even though I'm 52 degrees north. Within the narrow range that I've actually experienced, I'll take hot any day, even in a really hot summer the weather only reaches the mythical peaks of "too hot" for a few days that year.
And FYI, the correct term for the hot temperature you described is "311 Kelvins". NB: it's not "degrees Kelvin", because Kelvin is an absolute scale that starts from zero, not some high temperature labelled as "zero" because it seems cold to meatbags.
