According to the [[Koppen Climate Classification]], [[London]] has a [[oceanic climate|temperate oceanic climate]] ('''Cfb''').<ref>{{cite web|url=https://upload.wikimedia.org/wikipedia/commons/b/bb/Koppen_World_Map_%28retouched_version%29.png|title=World Map of Köppen-Geiger climate classification|last1=Peel|first1=M.C.|last2=Finlayson|first2=B.L.|publisher=The University of Melbourne |archive-url=https://web.archive.org/web/20150113015116/http://upload.wikimedia.org/wikipedia/commons/b/bb/Koppen_World_Map_%28retouched_version%29.png|archive-date=January 13, 2015|url-status=dead|access-date=27 June 2020}}</ref> This type of climate features cool winters with frequent cloudy skies and rain showers (and on occasion snow), and mild summers. [[Precipitation]] is fairly evenly distributed all year round. 

London has a very rich history of meteorological observations, with precipitation records beginning as early as January 1697 at [[Kew Gardens]].<ref>{{cite web|url=http://old.wetterzentrale.de/klima/pkewgar.html|title=Monthly precipitation totals KEW GARDENS 1697- 1987|publisher=Wetterzentrale.de|access-date=13 September 2020|archive-date=24 February 2021|archive-url=https://web.archive.org/web/20210224100657/http://old.wetterzentrale.de/klima/pkewgar.html|url-status=dead}}</ref> Irregular observations were made at multiple locations in the ensuing years.

The city can sometimes experience extremes.
