London sees mild summers and cool, rainy winters, with late spring through early fall (May-September) the most popular time to visit thanks to longer days and outdoor events. This peak season also brings higher fares and busier flights, so booking 2 to 3 months ahead is your best bet for a reasonable price during summer travel.
