The best time to visit Brazil would be March thru November because the climate is dryer. Some people like to visit in December thru February, the weather is hot, humid and rainy but is said to be a good time to visit. One of the best times to visit Iguazu Falls is during the rainy season (January to March) when the water flow of the waterfall is significantly increased.
