London temperature

Climate chart - London In London, the capital of Great Britain, the climate is influenced by the ocean and is therefore cool, humid and rainy. Atlantic fronts pass one after the other throughout the year, and bring variable weather, with cloudiness, rains and showers, which alternate, at least in spring and summer, with a few hours of sunshine. However, the climate is a bit milder than in the rest of Britain: the city is located in the south, and in a relatively sheltered area, called London Basin, between the Chiltern Hills to the north and the North Downs to the south. In this area, the climate is slightly warmer than in the surrounding region, except when a high pressure system arrives during winter, and causes thermal inversions and night fogs. As happens in the big cities, in the central and most densely populated districts, the so called urban heat island effect occurs, in fact, the temperature is slightly higher (about 2 degrees Celsius) than in the surrounding rural areas; this effect is more noticeable at night and in winter. At Heathrow Airport, located on the western outskirts of the city, the average temperature ranges from 5.6 °C (42 °F) in January to 19 °C (66.2 °F) in July. Here are the average temperatures.
