Why is it always humid during the summer months in London compared to the rest of england?

Question

I remember once in June i was over in Manchester and traveled down to London and felt a sharp difference in temprature as soon as i left the train. It can get redicolously humid in London now during the peak summer months, similar to mediteranean countries whereas the rest of the UK stays cooler.

Why is this??

I mean the weather being better in the south than the north is utter rubbish as it pretty much rains everywhere in england, no avoiding that lol, but i do notice that it is always warmer in London than the north and even in areas in the south but generally the south is warmer, espacially during the winter months whereas the north also brings that cold breeze, why is that????

Hope someone can give me good answers to both questions,,,thanks

Answer 1

well the south does have a warmer climate than the north

and also london is allot more packed up and dense in terms of buildings and London is allot busier.

more cars more people more packed = more pollution

that's what makes it seem more humid.

Answer 2

Because London is an incredibly urbanised area, and so the fumes from one of the several airports, the trains and hundreds of thousands of cars are going to create a humid atmosphere.
