Climate of London

[1] This type of climate features cool winters with frequent cloudy skies and rain showers (and on occasion snow), and mild summers.

London has a long history of meteorological observations, with precipitation records beginning as early as January 1697 at Kew Gardens.

An observing station has been located at Greenwich since 1841, giving London its longest continuous reliable temperature series.

[7] The highest temperature ever observed in London is 40.2 °C (104.4 °F) [8] recorded at both Heathrow Airport and St James's Park on 19 July 2022 and the lowest is −17.4 °C (0.7 °F) at Northolt on 13 December 1981.

The weather station enclosure is the most elevated of any in the London area, and as a result daytime temperatures are typically one degree lower than Heathrow, Kew, Northolt and Greenwich.
