@Darksideinthenight2 It's by no means "grey" all of the time, but the weather being changeable is one of the factors giving the countryside its rich natural diversity.
@Darksideinthenight2 What you hear is the British tendency to moan about the weather! It is not "mostly grey"; but neither is it semi-arid. The complaints are exaggerated because people tend to recall the bad more than the good. We are not alone in that - Europe's wettest city is Bergen, in Norway, and its locals are apparently are just as good at either complaining or joking about it.
Besides what do you mean by "good" or bad" or "better" weather? It is only those by taste. If we were in areas riven by frequent droughts, floods or hurricanes, or locked down for months on end by snow and bitter cold, we might have something to moan about.
What we have seen though in Britain in recent years is a blurring of the seasons, with more changeable Summers and milder, wetter Winters.
