I promise that I don't complain when it's not as warm and overcast. Yes, a lot of rain it's not great especially in the winter.
I wanted to say that before I say that I hate the summer in UK. Why? Here are the reasons:
I have a really bad hayfever. That means often choosing between baking at my home or opening the windows and blowing my brains out through my nose due to the allergy.
Very few places have air-con. Especially homes, meaning it's really hot and not much can be done about it. Also, when at work, it's annoying when it's so hot. It's nice when you are at the beach but this brings me to the next point.
The weather is unreliable. It can be hot as fuck the whole week and then when you go to the beach it's cold and windy.
Honestly sometimes aircon is a curse too - we bought one of those portable units, it's great and turns our bedroom baltic but if you forget to turn it off you wake up with a really bad cotton mouth and an electric bill that makes you question your life choices
