Rio de Janeiro
Geography
The city reputedly has had rare frosts in the past, but this has never been decisively confirmed. Some areas within Rio de Janeiro state occasionally have falls of snow grains and ice pellets (popularly called granizo, or "hail", although it is in fact melted and refrozen snow falling in the form of hail, rather than just icy snow). These phenomena are definitely not rare or limited to a few regions,[original research?] having already happened in the metropolitan area (including western suburbs of the city itself) several times in the 21st century.
