Snow in southern Brazil

Snow in Southern Brazil
In Brazil, the temperature scale is standardized in degrees Celsius, the winter months are June, July and August.
And it is cold mainly in the south of Brazil where it snows for a few days a year. In the Southeast where São Paulo is located, it is also cold, but not so much. Where I live, the lowest temperatures should reach between 6 and 9 degrees and this lasts for about 3 days, then it warms up again.
