The seasons are defined by flood and ebb. The Summer (wet) transforms the Pantanal into a vast flooded plain, while Winter (dry) is extremely dry, with relative humidity dropping below 20%. The Brazilian "winter" here is a desert-like season.
This densely populated region has a true tropical seasonality. Summer brings torrential, often catastrophic, rainfall (e.g., flooding in São Paulo). Winter (June-August) is mild (15-20°C) and dry, with the occasional passage of friagens (cold fronts from the South) dropping temperatures suddenly. season in brazil

Unlike countries in the Northern Hemisphere, Brazil’s seasons are reversed: Summer occurs from December to March, and Winter from June to September. However, due to Brazil’s proximity to the Equator (92% of the country lies within the intertropical zone), seasonal temperature variation is often less significant than seasonal precipitation variation. This paper argues that rainfall seasonality , rather than thermal seasonality, is the primary driver of ecological, agricultural, and social rhythms in most of Brazil.
The Equatorial Amazon does not experience traditional seasons. Instead, it has a rainy season (December to May) with river flooding, and a dry season (June to November) with lower river levels and increased forest fires. Temperature variation is minimal (average 26-28°C year-round).
