Snow in Brazil
Snow in Brazil occurs virtually every year in some cities of the high plains of the southern states of Rio Grande do Sul, Santa Catarina, and Paraná. They account for approximately 23,000 km2 (8,900 sq mi) and are the coldest cities in the country, where snow can happen when polar air masses reach the region: São Joaquim, Urubici, Urupema, and São José dos Ausentes, among other cities such as Bom Jesus, Bom Jardim da Serra, Cambará do Sul, and Palmas.
On 7 August 1879, the greatest snowfall ever recorded in Brazil happened in Vacaria, with more than 2 meters of accumulated snow. Snowfalls like this are extremely rare in Brazil, the three below being the only ones that reached(or passed) 1 meter:
Although snow in Brazil is normally reserved only to high elevation areas, there are also many reports of snow precipitation in low elevation locations such as Ijuí and Porto Alegre (330 meters and 10 meters above sea level, respectively).
Besides these three states, snow precipitation also occurs more rarely in São Paulo (last time in Apiaí in 1975) and Rio de Janeiro (last time at Itatiaia, at the Pico das Agulhas Negras, in 1985), thus making five states with snow precipitation reported in the country.
The city of São Paulo has witnessed a phenomenon very similar to the precipitation of snow, the sublimation fog on June 26, 1918. At the time, the water network froze in the city.
