Answer:
London, England has what is called a maritime climate so it has a smaller range of temperatures. It is milder in winter than areas at the same latitude that are inland. It is also cooler in summer than areas inland that will have hotter summers.
Explanation:
The weather in the British Isles is influenced by the ocean. London is at roughly the same latitude as places with very harsh winters like Minneapolis, Minnesota, which often contends with artic air pushed down due to pressure systems across the North American continent. The UK benefits from a milder climate because of the ocean currents.
