Overview of London’s Climate
London’s climate is classified as temperate maritime, which is typical of much of the United Kingdom. This means that the city rarely experiences extreme temperatures, with winters that are generally mild and summers that are moderately warm. The influence of the Atlantic Ocean and the Gulf Stream ensures that London’s weather is milder than many other cities at similar latitudes. While snow is rare in London, rain is a frequent visitor, contributing to the city’s lush green parks and gardens.
Key Features of London’s Climate
- Mild winters with average lows around 2-4°C (36-39°F).
- Cool summers with average highs around 22-24°C (72-75°F).
- Year-round precipitation, with rainfall spread fairly evenly across all months.
- Frequent overcast skies and occasional fog, especially in autumn and winter.
The city’s climate is also heavily influenced by urbanization. The "urban heat island" effect means that London can be a few degrees warmer than surrounding rural areas, particularly in winter. This phenomenon is caused by the concentration of buildings and human activity, which retain heat.
