=== Climate ===
Montevideo has a [[Humid subtropical climate]] ([[Köppen climate classification|Köppen]] [[Humid subtropical climate|Cfa]]) in a middle latitude, the city experiences the four seasons. It has cool winters (June to August), warm to hot summers (December to February), mild autumns (March to May) and volatile springs (September to November);<ref name="Climate">{{Cite web |title=About the Climate in Montevideo, Uruguay:Overview |url=http://traveltips.usatoday.com/climate-montevideo-uruguay-16170.html |access-date=16 November 2010 |publisher=Traveltips |archive-date=30 November 2010 |archive-url=https://web.archive.org/web/20101130012826/http://traveltips.usatoday.com/climate-montevideo-uruguay-16170.html |url-status=live }}</ref> The climate is characterized by having mild temperatures, without harsh cold or extreme heat. There are numerous thunderstorms but no tropical cyclones. Rainfall is regular and evenly spread throughout the year, reaching around {{convert|950|mm|in|sp=us}}.<ref>{{Cite web |title=Montevideo climate: Average Temperature, weather by month, Montevideo weather averages - Climate-Data.org |url=https://en.climate-data.org/america-del-sur/uruguay/montevideo/montevideo-3639/ |access-date=20 September 2019 |website=en.climate-data.org |archive-date=8 March 2021 |archive-url=https://web.archive.org/web/20210308104313/https://en.climate-data.org/america-del-sur/uruguay/montevideo/montevideo-3639/ |url-status=live }}</ref>

Winters are generally cool, wet, windy and overcast. The average temperature during this season is just above {{cvt|10|C|F}}. Daytime temperatures are generally between {{cvt|10|C|F}} and {{cvt|18|C|F}}, and night lows between {{cvt|3|C|F}} and {{cvt|10|C|F}}. During this season, there are bursts of icy and relatively dry winds of continental polar air masses, giving an unpleasant chilly feeling to the everyday life of the city, with daytime temperatures around or below {{cvt|8|C|F}} and possible night frosts. These occur few times during winter, with temperatures generally not falling below {{cvt|-2|C|F}} because of the oceanic influence that moderates the temperature; a few kilometres inland, frosts are more common and colder. On the other hand, even in the middle of winter it's not uncommon to have temperatures above {{cvt|20|C|F}} for a few days. Rainfall and [[Ice pellets|sleet]] are a frequent winter occurrence, but snowfall is extremely rare: flurries have been recorded only four times but with no accumulation, the last one on 13 July 1930 during the inaugural match of the [[1930 FIFA World Cup|World Cup]],<ref>{{Cite web |last=FIFA World Cup |title=1930 FIFA World Cup Uruguay : Hosts Uruguay beat arch-rivals to first world crown |url=https://www.fifa.com/worldcup/archive/edition=1/overview.html |archive-url=https://web.archive.org/web/20070620232908/http://fifa.com/worldcup/archive/edition=1/overview.html |url-status=dead |archive-date=20 June 2007 |access-date=14 July 2011 |publisher=FIFA World Cup |location=Zúrich, Suiza}}</ref> (the other three snowfalls were in 1850, 1853 and 1917); the alleged 1980 [[Carrasco, Montevideo|Carrasco]] snowfall was actually a [[hail]]storm.<ref>{{Cite web |last=Andrés Silva Delgado |date=Dec 2010 |title=¿Nevó en Uruguay en el mes de Noviembre? |trans-title=Did it snow in Uruguay on November? |url=http://www.meteorologia.gub.uy/pdf/rrpp/23_43099.pdf |url-status=dead |archive-url=https://web.archive.org/web/20120124230720/http://www.meteorologia.gub.uy/pdf/rrpp/23_43099.pdf |archive-date=24 January 2012 |access-date=29 June 2011 |publisher=Dirección Nacional de Meteorología |location=Montevideo, Uruguay |page=1 |language=es }}</ref>

Summers are warm-hot and humid, with less wind than other seasons. The average temperature in this season is 
{{cvt|23|C|F}}. Daytime temperatures are usually between {{cvt|24|C|F}} and {{cvt|32|C|F}}, while night lows between {{cvt|14|C|F}} and {{cvt|22|C|F}}. During this season, a moderate wind often blows from the sea in the evenings which has a pleasant cooling effect on the city, in contrast to the more severe summer heat of nearby cities like [[Buenos Aires]].<ref name=Climate/> Heat waves come with the north winds, which bring humid and hot air masses from the tropical interior of the continent; temperatures can rise above {{cvt|35|C|F}}. These warm periods are usually followed by thunderstorms, generated by cold fronts from the southwest that lowers temperatures considerably. This phenomenon is regional, and can occur several times all year long.

The autumn in Montevideo is quite pleasant and not so unstable. Daytime temperatures are in general around {{cvt|20|C|F}} and nights around {{cvt|10|C|F}}.
Spring average temperatures are very similar to the autumn, but the weather in that season tends to be more windy and volatile, with more dramatic changes in a short period of time.

Montevideo has an annual average temperature of {{cvt|16.7|°C|1}}. The lowest recorded temperature is {{cvt|−5.6|°C|°F}} while the highest is {{cvt|42.8|°C|°F}}.<ref name = DNM1 />
