Yes,in UK the highlands are extremely cold while places like London are way warmer.Due to the Highlands being located in the North,and the way the cold wind blows in from the North Pole,the area tends to be colder and snows a lot more in the winter.
London,on the other hand,is more populated and the pollution also play a factor in making the air warmer.London is also nearer South,making it naturally warmer.
