===Climate===
Hamburg has an [[oceanic climate]] ([[Köppen climate classification|Köppen]]: ''Cfb''; [[Trewartha climate classification|Trewartha]]: ''Dobk''), influenced by its proximity to the coast and maritime influences that originate over the Atlantic Ocean. The location in the north of Germany provides extremes greater than typical marine climates, but definitely in the category due to the prevailing westerlies.<ref>{{cite web|url=http://www.weatherbase.com/weather/weather-summary.php3?s=74101&cityname=Hamburg,+Hamburg,+Germany&units=metric|title=Hamburg, Germany Köppen Climate Classification (Weatherbase)|website=Weatherbase|access-date=7 February 2019|archive-date=25 July 2023|archive-url=https://web.archive.org/web/20230725055124/http://www.weatherbase.com/weather/weather-summary.php3?s=74101&cityname=Hamburg,+Hamburg,+Germany&units=metric|url-status=dead}}</ref> Nearby wetlands enjoy a maritime temperate climate.
