The climate of London features a temperate oceanic variety (Cfb). This gives the city cool winters, warm summers with frequent precipitation all year round. London has a very rich history of meteorological observations, with precipitation records beginning as early as January 1697 at Kew Gardens. Irregular observations were made at multiple locations in the ensuing years. An observing station has been located at Greenwich since 1841, giving London its longest continuous reliable temperature series. Other stations include Heathrow, beginning in 1948, Hampstead, beginning in 1910, Northolt, beginning in 1948, and St James's Park, beginning in 1910.
The highest temperature ever observed in London is 38.1 °C (100.6 °F) on 10 August 2003 and the lowest is −16.1 °C (3.0 °F) 1 January 1962. The lowest daily maximum temperature is −8.3 °C (17.1 °F) occurring on 3 occasions: 8 January 1841, 4 January 1867 and 12 January 1987. The highest daily minimum temperature recorded is 23.3 °C (73.9 °F) on 29 July 1948. This is also the highest minimum temperature ever reported during the month of July in the United Kingdom. In addition to this, London holds multiple national records, including the record maximum for the months of February, April, May and June.
The city can sometimes experience extremes. Snowfall is an infrequent occurrence in winter; between 1961 and 1990 it fell on an average of 16 days per year, although infrequently heavily. This number has decreased markedly since 1990. Thunderstorms are a similarly occurring feature, occurring on average up to 16 days per year. London has been known to experience tornadoes. An F2 struck Kensal Green on 7 December 2006.
