London: choose the season before the trip style
The lowest and highest average daily highs are 15.7 °C apart. Temperature is therefore the first decision layer, while rain and sunshine refine the choice of month.

For your trip planning
London: build a weather-flexible day
Combine outdoors and indoors
London offers parks and walks as well as theatre. Our planning suggestion: place longer outdoor stretches in the better weather window and keep an indoor option ready. A low climate score is not a verdict on a cultural trip.

Plan for the evenings too
Compare your month's average high and low. If you plan to walk after a theatre visit, do not choose clothing from the daytime figure alone. Sunshine hours in our data are not the duration of daylight.
