In summer, London gets significantly warmer, and the sun tends to stay out longer, making it ideal for spending the day in parks or engaging in outdoor activities. Although rain can still occur, the days are generally longer, and there are many more things to do in the city.
In winter, the weather in London turns colder, and it gets dark earlier, resulting in shorter days. It can rain quite a bit and sometimes be windy, so it’s good to have warm clothing and an umbrella handy. The city looks beautiful with Christmas lights, and there are festive markets to visit. While it doesn’t get as cold as in other parts of Europe, there can be occasional snowfall.
