The weather is worth considering when planning a trip to Brazil, as it can have a significant bearing on how you enjoy certain regions of the country. For example, the Amazon region is one of the world’s rainiest places, making travel exceedingly difficult between January and May. Similarly, if you plan to go to the Pantanal, do so during the dry season. The rest of the year, roads are washed out and travel is a nightmare. The south has the most extreme temperatures and during the coldest winter months snow is even possible – but rare.
During summer (December-February) many Brazilians are on vacation, making travel expensive and frequently booked out, and, from Rio to the south, the humidity can be oppressive. However, summer is also the most festive time of year, as Brazilians take to the beaches and streets. School holidays begin in mid-December and go through to Carnaval, usually held in late February.
Brazil’s low season corresponds to its winter. Rio temperatures hover around 23°C (73°F), with a mix of both rainy and superb days. With the exception of July, which is also a school-holiday month, this is the cheapest and least-crowded time to visit the country.
