Rio has a [[tropical savanna climate]] (''Aw'') that closely borders a [[tropical monsoon climate]] (''Am'') according to the [[Köppen climate classification]], and is often characterized by long periods of heavy rain between December and March.<ref>{{Cite journal |last1=Alvares |first1=Clayton Alcarde |last2=Stape |first2=José Luiz |last3=Sentelhas |first3=Paulo Cesar |last4=de Moraes Gonçalves |first4=José Leonardo |last5=Sparovek |first5=Gerd |year=2013 |title=Köppen's climate classification map for Brazil |journal=Meteorologische Zeitschrift |publisher=E.

In inland areas of the city, temperatures above {{cvt|40|°C|0}} are common during the summer, though rarely for long periods, while maximum temperatures above {{cvt|27|°C|0}} can occur on a monthly basis.

Along the coast, the breeze, blowing onshore and offshore, moderates the temperature. Because of its geographic situation, the city is often reached by cold fronts advancing from [[Antarctica]], especially during autumn and winter, causing frequent weather changes. In summer there can be strong rains, which have, on some occasions, provoked catastrophic floods and landslides. The mountainous areas register greater rainfall since they constitute a barrier to the humid wind that comes from the Atlantic.<ref>{{Cite web |title=BBC Weather – Rio de Janeiro |url=http://www.bbc.co.uk/weather/3451190 |access-date=14 May 2015 |website=BBC Weather |archive-date=1 May 2015 |archive-url=https://web.archive.org/web/20150501091522/http://www.bbc.co.uk/weather/3451190 |url-status=live }}</ref> The city has had rare [[frost]]s in the past.

Drought is very rare, albeit bound to happen occasionally given the city's strongly seasonal tropical climate. The Brazilian drought of 2014–2015, most severe in the [[Southeast Region, Brazil|Southeast Region]] and the worst in decades, affected the entire metropolitan region's water supply (a diversion from the [[Paraíba do Sul]] River to the [[Guandu River (Rio de Janeiro)|Guandu]] River is a major source for the state's most populous mesoregion). There were plans to divert the Paraíba do Sul to the [[Sistema Cantareira]] (Cantareira system) during the water crisis of 2014 in order to help the critically drought-stricken [[Greater São Paulo]] area. However, availability of sufficient rainfall to supply tap water to both metropolitan areas in the future is merely speculative.<ref>{{Cite web |date=5 September 2014 |title=Brazil drought crisis leads to rationing and tensions |url=https://www.theguardian.com/weather/2014/sep/05/brazil-drought-crisis-rationing |access-date=2 February 2015 |website=The Guardian |archive-date=21 June 2022 |archive-url=https://web.archive.org/web/20220621125416/https://www.theguardian.com/weather/2014/sep/05/brazil-drought-crisis-rationing |url-status=live }}</ref><ref>{{Cite news |date=23 January 2015 |title=Brazil's worst drought in history prompts protests and blackouts |work=The Guardian |url=https://www.theguardian.com/world/2015/jan/23/brazil-worst-drought-history |access-date=2 February 2015 |archive-date=21 June 2022 |archive-url=https://web.archive.org/web/20220621125407/https://www.theguardian.com/world/2015/jan/23/brazil-worst-drought-history |url-status=live }}</ref><ref>{{Cite web |date=1 February 2015 |title=Paraíba do Sul River might not have enough water to rescue São Paulo's Sistema Cantareira |url=http://g1.globo.com/fantastico/noticia/2015/02/rio-paraiba-do-sul-pode-nao-ter-agua-para-socorrer-sistema-cantareira.html |access-date=2 February 2015 |publisher=G1 |language=pt |archive-date=21 June 2022 |archive-url=https://web.archive.org/web/20220621123613/https://g1.globo.com/fantastico/noticia/2015/02/rio-paraiba-do-sul-pode-nao-ter-agua-para-socorrer-sistema-cantareira.html |url-status=live }}</ref>

Temperature also varies according to elevation, distance from the coast, and type of vegetation or land use. During the winter, cold fronts and dawn/morning sea breezes bring mild temperatures; cold fronts, the [[Intertropical Convergence Zone]] (in the form of winds from the [[Amazon Forest]]), the strongest sea-borne winds (often from an [[extratropical cyclone]]) and summer [[evapotranspiration]] bring showers or storms. Thus the monsoon-like climate has dry and mild winters and springs, and very wet and warm summers and autumns. As a result, temperatures over {{cvt|40|°C|0}}, that may happen about year-round but are much more common during the summer, often mean the actual "feels-like" temperature is over {{cvt|50|°C|0}}, when there is little wind and the [[relative humidity]] percentage is high.<ref>{{Cite web |date=23 February 2010 |title=Com sensação térmica de 48&nbsp;°C, cariocas se refugiram do calor nas praias |trans-title=Feeling like 48&nbsp;°C, cariocas bathe in beaches trying to escape from the heat |url=http://g1.globo.com/Noticias/Rio/0,,MUL1502179-5606,00-COM+SENSACAO+TERMICA+DE+C+CARIOCAS+SE+REFUGIAM+DO+CALOR+NAS+PRAIAS.html |url-status=dead |archive-url=https://web.archive.org/web/20100226030724/http://g1.globo.com/Noticias/Rio/0%2C%2CMUL1502179-5606%2C00-COM%2BSENSACAO%2BTERMICA%2BDE%2BC%2BCARIOCAS%2BSE%2BREFUGIAM%2BDO%2BCALOR%2BNAS%2BPRAIAS.html |archive-date=26 February 2010 |access-date=25 June 2013 |publisher=G1 |language=pt}}</ref><ref>{{Cite web |date=25 December 2012 |title=Sensação térmica no Rio de Janeiro chega a 50&nbsp;°C nesta terça-feira |trans-title=Rio de Janeiro will be feeling like 50&nbsp;°C this Tuesday |url=http://br.noticias.yahoo.com/sensa%C3%A7%C3%A3o-t%C3%A9rmica-rio-de-janeiro-chega-a-50-233457951.html |access-date=25 June 2013 |publisher=Yahoo!
