September is great for Bahia, especially for the southern Bahian beaches. It is the month when you can still see whales. Also great time to see the colonial towns of Minas Gerais.
September is another prime month for wildlife in the Amazon. Activities: fishing for piranha and night walks, as well as 4×4 safaris and kayaking.

At the Iguazu Falls the temperature are more comfortable and the risk of rain is smaller. Although the falls are not at their peak, they remain impressive and the rocks peeking through the water can make the falls very spectacular.
It is better to avoid the beaches of Santa Catarina and Rio Grande do Sul due to cold temperatures, as well as the canyons of Aparados da Serra due to rain and low visibility.
