Colder than ever The city of São Paulo uses to have a warm weather. Even during the winter, the temperature may reach near 23 degrees Celsius, while the real felling can get even higher as the sun warms the inhabitants. It is not like in Rio de Janeiro, where 20 degrees Celsius leads the population to get theirs snow-coats out of their wardrobe, but the city is mainly unused to cold. This year the winter hasn't even begun, but a polar air mass has made the temperature fall more than the usual. Yesterday it reached near 1 degree, forcing the municipal government to stay on alert. On other cities nearby, the water froze in the pipes causing disruption of the supply. The forecast for the next days is that the temperatures are going to remain low, but that the worst has already passed.
