London's weather is known for being quite unpredictable. In fact, Londoners regularly carry both sunglasses and an umbrella throughout the year. But London's weather is never so extreme as to detract from all the great things to do in the city.

The hottest month of the year is normally August when the peak temperature can be 30°C (90°F) but the average temperature in August is about 22°C (70°F). The coldest month is usually January when temperatures can sink to around 1°C (33°F).

Snow is pretty rare in London but if it does fall it's typically in January or February. Some rail services can be affected by adverse weather conditions. Don't forget to check with your transportation provider before traveling if snow is forecast. 

London is a year-round destination, so major attractions are not affected by seasonality. There's typically an increase in visitors in July and August so it's best to plan a trip at a different time of the year to avoid overcrowding.

In general, London's weather is mild year-round, but just remember to pack a lightweight raincoat to keep in your daypack. The seasons change gradually and winter can appear to still be hanging on when it should be spring, but the weather is never so bad to stop you from planning to get out and about. There's so much to do in London, both indoors and outdoors that you'll never have to worry about the weather spoiling your plans.

 You'll always find something happening in this vibrant city!
