São Paulo is no longer “the misty city.” According to the study “Meteorology and Atmospheric Pollution in São Paulo,” by the University of São Paulo, increases in average temperature over the last 40 years have led to a reduction in the mists and fogs that once characterized the city.
São Paulo enjoys a high-altitude tropical climate, with summer rains and an average temperature of from 19º to 27 ºC. It is possible to experience all four seasons in just one day. In the morning, the weather can be sunny and cloudless yet the day may end with a storm. This is why Paulistanos often carry jackets and umbrellas, even on hot days.
In the summer, it usually rains at the end of the afternoon, cooling things off. In the fall, the temperature is pleasant at an average of around 23ºC. Winter days are sunny and dry with temperatures that rarely dip below 15ºC. In the spring, it is usually warm and dry.
