I honestly feel like the UK has the best weather. Not too cold, not too hot and almost always manageable. I am baffled by people who complain. I used to live in California and the heat waves could be intense, with very expensive air conditioning bills and I don't miss the burning sensation you could get when you touched a black steering wheel or sat on hot leather of a car that was parked outside. I have also spent time in Lapland and lived in Minnesota, so I know what it's like to step outside in to a cold that is painful.
AIBU to think there is no reason to complain about the weather here? I love it!
