[[Jersey]] ([[Jèrriais]]: ''Jèrri'') is the largest of the [[Channel Islands]], an island archipelago in the St. Malo bight<ref name=":02"/> in the western [[English Channel]]. It has a total area of {{convert|120|km2|mi2|abbr=out}} and is part of the British Isles archipelago. It lies {{convert|22|km|nmi mi}} from the [[Cotentin Peninsula]] in [[Normandy]], France and about {{convert|161|km|nmi mi}} from the south coast of [[Great Britain]]. Jersey lies within longitude [[2nd meridian west|-2° W]] and latitude [[49th parallel north|49° N]]. | |||
It has a coastline of 70 kilometres and no land connections to any other territories. Jersey claims a territorial sea of {{convert|3|nmi|km mi|1|abbr=on|lk=in}} and an exclusive fishing zone of {{convert|12|nmi|km mi|1|abbr=on}} and shares maritime borders with the [[Bailiwick of Guernsey]] to the north and [[France]] to the south and east. | It has a coastline of 70 kilometres and no land connections to any other territories.

Jersey is indeed one of the sunniest places in the British Isles, especially during the warmer months, as it is subject to more influence from the [[Azores High]], which acts as a blocking mechanism for [[Low-pressure area|depressions]] that originate in the North Atlantic and that produce stratiform clouds and rain; these are deflected northwards towards the UK mainland. The [[Azores High]] further reduces the type of convective cloud formations (particularly [[Cumulus cloud|Cumulus]] and [[Stratocumulus cloud|Stratocumulus]]) that are common over more northern and inland areas of the UK during summer through [[Subsidence (atmosphere)|subsidence]]. | |||
In 2011, Jersey generated controversy for calling itself "the warmest place in the British Isles" during an advertising campaign, as Jersey is neither the place with the highest maximum temperature in the British Isles ({{convert|40.3|°C|°F|1|disp=or}} was recorded in [[Coningsby]], [[Lincolnshire]] in July 2022<ref>{{Cite web |title=Record high temperatures verified |url=https://www.metoffice.gov.uk/about-us/news-and-media/media-centre/weather-and-climate-news/2022/record-high-temperatures-verified |access-date=2024-07-25 |website=Met Office |language=en}}</ref>) or the highest winter temperatures in the British Isles (which would be the [[Isles of Scilly]]).<ref>{{Cite news |date=10 April 2011 |title=Isles of Scilly turn heat on Jersey over 'warmest place in Britain' claim |url=http://www.theguardian.com/uk/2011/apr/10/isles-of-scilly-jersey-warmest-britain |url-status=live |archive-url=https://web.archive.org/web/20220320143448/https://www.theguardian.com/uk/2011/apr/10/isles-of-scilly-jersey-warmest-britain |archive-date=20 March 2022 |access-date=29 March 2023 |work=[[The Guardian]] |language=en}}</ref> | |||
Typical wind speeds vary between {{convert|20|kph}} and {{convert|40|kph}}. During the cooler months, [[Extratropical cyclone|extratropical cyclones]] can produce [[Gale|gales]] somewhat regularly. | |||
Snow is very rare in Jersey.

Extreme weather is rare due to the island's mild climate. Spring and summer thunderstorms originating from the European mainland occasionally occur, but are usually not severe. Thunderstorms [[Advection#Meteorology|advecting]] north from the [[Bay of Biscay]] tend to occur during the summer if the influence of the [[Azores High]] temporarily weakens and a [[cut-off low]] develops in the region. Cool season thunderstorms are more common compared with other parts of Europe, as the relatively warm sea-surface temperatures drive moderate surface-based convection into the cold, dry air aloft. This tends to result in [[Hail|small hail]] and weak [[Waterspout|waterspouts]] driven by convection and frequent shear brought on by [[Cold front|cold fronts]].{{cn|date=November 2024}} | |||
In November 2023, Jersey was hit by extratropical [[Storm Ciarán]], causing heavy rainfall, extremely high winds with gusts of up to {{convert|104|mph|0}}.<ref>{{Cite tweet |number=1719955319512563725 |user=JsyFire |title=As wind speed increases we're seeing an increase in calls. ...}} – Jersey Fire & Rescue</ref> A [[supercell]] thunderstorm associated with the [[cold front]] of this system hit Jersey at around midnight on 2 November 2023.
