Weather across England can be unreliable and unpredictable, with lovely sun-drenched mornings regularly turning into damp, overcast afternoons—and vice versa. London's summers tend to be moderately warm and winters moderately cold, with spring and autumn generally requiring little more than a sweater or light overcoat. Scotland's climate is infamous for its ability to change from day to day. Cool, mild weather, accompanied by frequent cloud cover and rain, is the norm. Wales has a more temperate climate than Scotland and England. As a general rule, Wales is cloudier, wetter, and milder than the eastern side of Great Britain.
