Snow in Brazil occurs yearly in the high plains of the country's South Region (comprising the states of Rio Grande do Sul, Santa Catarina, and Paraná). Elsewhere in the country it is a rare phenomenon but has been registered several times.
The phenomenon occurs mainly during the months of June, July and August. In this period, São Joaquim, the city with the most snow days, receives an average of 13,000 visitors from other parts of Brazil.[1]
The greatest snowfall ever recorded in the country occurred in Vacaria (RS) on 7 August 1879, with more than 2 metres (79 inches) of accumulated snow.[2][3] Snowfalls like this are extremely rare in Brazil, the two below being the only later snowfalls that reached (or passed) 1 metre (39 inches):
