-8,18 ºC in Urupema, Santa Catarina, widespread frost in the south and snow in some places. This winter has been strong. In late June there was the first snowfall of the year in the south, then in early July frost hit São Paulo and damaged sugarcane and maize fields. 
It's worth noting how in a certain subtropical climate range, frost is a mini-catastrophe as it's expected only in a certain stretch of the year or not at all, and hits crops hard. For a natural disaster it's also unusually beautiful and, for the warmest climates that can still receive it, exotic. It's also poor man's snow, a lot less prestigious but happening on surprisingly low latitudes.
