Initialism of So Paulo, A state of Brazil.

So Paulo is one of 27 states of Brazil, located southwest of the Southeast Region. The state area is 248,222.362 km² (95,839.190 sq mi), most of the north of the Tropic of Capricorn, and the 12th unit of the Brazilian federation in area and the second in the Southeast region, behind only Minas Gerais.

Most of the rain falls December through March. The driest time of the year is May through October. In these winter months things cool down considerably, though nighttime temperatures will seldom drop below 20C (68F).

You might think Brazil is always warm, but some regions can get quite wet and chilly if you go in the middle of the year. To get the best weather  while avoiding the crowds who fill up the beaches once kids are out of school in the peak season  you should visit Brazil in either October or November.
