Climate and Vegetation of Brazil’s South Region25.4S 49.2W
Brazil’s South Region includes the states of Paraná, Santa Catarina and Rio Grande do Sul, which are visible from north to south, although Rio Grande do Sul is mostly obscured by clouds.
The region is almost entirely subtropical, with hot to moderately hot temperatures in the summer, and mild (though cold for Brazilian standards) and very humid winters.
The exceptions are the northeast part of the region, which has a tropical climate, and the highlands, where some occasional light snow might fall. In the northeast, it is hot in the summer and warm to cool during the winter.
The vegetation consists of rainforests along the coast (Mata Atlântica), tropical semiciduous vegetation in the north and west (Araucárias) and prairie-like vegetation in the south (Pampas). Deforestation is a serious problem for the native vegetation.
