Why do you think the weather in the UK isn’t good? Because it rains sometimes? Why’s that ‘bad’? There’s nothing wrong with rain. What do you want instead? Just bland boring sunshine all the time? How dull.
Well it sort of like.. depends. Comparatively speaking UK still has less Sunshines than lots of places on earth, but compare to 20 - 30 years ago UK, ( At least in the Southern Part like London ) now has really hot summer and decent weather.
Certainly here in eastern Australia at the moment, the lack of rain in this early summer is quite depressing. (The widespread bushfires and smoke is likely to be with us for the next few months)
