===Climate===
Chester has an [[oceanic climate]] ([[Köppen climate classification|Köppen]]: ''Cfb''), typical of the [[British Isles]] but more susceptible to cold than the extreme south.<ref>{{Cite web|url=https://en.climate-data.org/europe/united-kingdom/england/chester-13/|title=Chester climate: Average Temperature, weather by month, Chester weather averages - Climate-Data.org|website=en.climate-data.org|access-date=2019-02-15|archive-url=https://web.archive.org/web/20190215151827/https://en.climate-data.org/europe/united-kingdom/england/chester-13/|archive-date=15 February 2019|url-status=live}}</ref> Despite its proximity to the [[Irish Sea]], the temperature regime is similar to areas further inland, owing to the shelter provided by the [[Pennines]] to the northeast and the Welsh Mountains to the southwest. The nearest official weather station is at [[Hawarden Airport]], about {{convert|4|mi}} west of the city centre.

The absolute maximum temperature recorded was {{convert|37.1|C|F}} on 18 July 2022, the highest temperature reported in Wales. In an average year, the warmest day should reach {{convert|29.3|C|F}},<ref>{{cite web
