how hot does it get in the summer in Brazil?

Answer 1

Well, first off, Brasil is the largest country in South America, and so probably has different climates depending on where you are, but.... (sorry for the formatting).. looks like it gets up to 44.8 degC in Bom Jesus do Piaui. That's pretty hot.
