Most of Tennessee has a [[humid subtropical climate]], with the exception of some of the higher elevations in the Appalachians, which are classified as a cooler [[oceanic climate|mountain temperate]] or [[humid continental climate]].<ref name=Climate>{{cite web |title=World Map of Köppen−Geiger Climate Classification |url=http://koeppen-geiger.vu-wien.ac.at/pdf/kottek_et_al_2006_A1.pdf |access-date=December 19, 2008 |url-status=dead |archive-url=https://web.archive.org/web/20090114202025/http://koeppen-geiger.vu-wien.ac.at/pdf/kottek_et_al_2006_A1.pdf |archive-date=January 14, 2009}}</ref> The [[Gulf of Mexico]] is the dominant factor in Tennessee's climate, with winds from the south responsible for most of the state's annual precipitation. Generally, the state has hot summers and mild to cool winters with generous precipitation throughout the year. The highest average monthly precipitation usually occurs between December and April. The driest months, on average, are August to October. The state receives an average of {{convert|50|in|cm}} of precipitation annually. Snowfall ranges from {{convert|5|in|cm}} in West Tennessee to over {{convert|80|in|cm}} in East Tennessee's highest mountains.<ref name="Tennessee Agriculture">{{cite web |url=http://www.agclassroom.org/kids/stats/tennessee.pdf |title=A look at Tennessee Agriculture |publisher=Agclassroom.org |access-date=November 1, 2006 |archive-url=https://web.archive.org/web/20160614025708/http://www.agclassroom.org/kids/stats/tennessee.pdf |archive-date=June 14, 2016}}</ref><ref>{{cite news |url=https://weather.com/safety/winter/news/snowiest-places-most-snow |title=The Snowiest Places in Each State |publisher=The Weather Channel |first=Nick |last=Wiltgen |date=October 27, 2016 |access-date=July 2, 2019 |archive-url=https://web.archive.org/web/20190604025229/https://weather.com/safety/winter/news/snowiest-places-most-snow |archive-date=June 4, 2019 |url-status=live}}</ref>

Summers are generally hot and humid, with most of the state averaging a high of around {{convert|90|F|C|0}}. Winters tend to be mild to cool, decreasing in temperature at higher elevations. For areas outside the highest mountains, the average overnight lows are generally near freezing. The highest recorded temperature was {{convert|113|F|C}} at [[Perryville, Tennessee|Perryville]] on August 9, 1930, while the lowest recorded temperature was {{convert|-32|F|C}} at [[Mountain City, Tennessee|Mountain City]] on December 30, 1917.<ref>{{cite web |title=Nashville Weather Records (1871-Present) |url=https://www.weather.gov/ohx/otherrecords |website=weather.gov |publisher=National Weather Service |access-date=May 27, 2021 |location=Nashville}}</ref>

While Tennessee is far enough from the coast to avoid any direct impact from a hurricane, its location makes it susceptible to the remnants of tropical [[cyclone]]s, which weaken over land and can cause significant rainfall.{{Tropical Cyclone Rainfall in the Southeastern United States}} The state annually averages about 50 days of thunderstorms, which can be severe with large hail and damaging winds.<ref name="Thunderstorm Hazard">{{cite web |url=http://www.srh.noaa.gov/key/HTML/tstmhazards.htm |title=U.S. Thunderstorm distribution |publisher=src.noaa.gov |access-date=November 1, 2006 |archive-url=https://web.archive.org/web/20061015060809/http://www.srh.noaa.gov/key/HTML/tstmhazards.htm<!--Bot retrieved archive--> |archive-date=October 15, 2006}}</ref> Tornadoes are possible throughout the state, with West and Middle Tennessee the most vulnerable.
