Brazil's tropical climate makes it a year-round destination for hikers. However, the country's vast size contributes to regional variations. Coastal areas, with mild temperatures, can be hiked all year, though the summer (December-March) can be wet.
The Amazon region, characterized by high humidity and rainfall, is less accessible during the rainy season (November-April). Conversely, the dry season offers better trail conditions and wildlife viewing opportunities.
In the Pantanal and the highlands, dry winter months (May-September) are preferable for hiking.
