The Info List - Climate Of London


--- Advertisement ---



London, the capital and largest city in England and the United Kingdom has a temperate oceanic climate, with warm summers and cool but not cold winters. While the city annually has modest precipitation, there are long periods of overcast skies and frequent light mist-type precipitation, which is likely responsible for the rainy image of the city. Within the current boundaries of Greater London, the coldest temperature ever measured was −16.1 °C (3.0 °F) at Northolt in January 1963, and the highest temperature ever recorded was 38.1 °C (100.6 °F), measured at Kew Gardens
Kew Gardens
during the European Heat Wave of 2003. London
London
averages about 1600 hours of sunshine annually. London's large built-up area creates a microclimate (an "urban heat island"), with heat stored by the city's buildings. Sometimes temperatures are 5 °C (9 °F) warmer in the city than in the surrounding areas.
