The North region registers the country's highest volume of precipitation, averaging between 2,182 mm and 3,000 mm annually. Powered by the equatorial climate, moisture from the Atlantic Ocean continuously feeds the Amazon Rainforest.

Brazil is not a monolith; meteorologically, it is a continent disguised as a country. To review "average rainfall" in Brazil is to analyze a complex collision of six major ecosystems. While the global perception is that of a monolithic Amazonian jungle, the reality is a sharp dichotomy between one of the wettest places on Earth and a semi-arid region prone to drought. | ~800 | | | Driver | Type
