Summer can be very pleasant with temperatures averaging 18°C (64°F) and often into the low 20s. In recent years London has experienced heatwaves with temperatures well above 30°C (86°F). This is an ideal time to visit London's parks and open spaces or have a go at swimming and boating in London.

Winter Weather

Typical temperatures for winter are between 2 and 6°C (36 to 43°F). Temperatures don't often drop below freezing and snow isn't common – although occasionally London does experience heavy snowfall and an army of snowmen pop up all over the city! Don't miss the stunning Christmas decorations in London or the famous New Year's Eve fireworks.
