WEATHER IN BRAZIL
Depending on where you go in Brazil, weather could be a significant factor in your travel plans. In Rio, the humidity is generally higher in the summer months, although temperatures rarely rise above 30C (86F); rain falls mainly from October to January. In winter the temperature in Rio is around 23C (73F), with a mixture of rainy days and stunning days.
On the northeast coast, from Bahia to Maranhao, temperatures are a bit warmer year-round than in Rio – close to 28C (82F) – but with a wonderful tropical breeze and less humidity, it’s a comfortable heat that feels amazing. The rainy season is from mid-April to mid-July, though you will still have beautiful days of sunshine.
In the northern Amazon region you will find one of the world’s wettest places and rainfall occurs most often from January to May, which can make travelling then more difficult. From June to December the region still receives plenty of rain, but showers tend to last only an hour or two.
The South has the most extreme temperature changes, and during the coldest winter months (June to August), Rio Grande do Sul, Santa Catarina, Parana and Sao Paulo have temperatures between 13C (55.4F) and 18C (64.4F). In some towns, snow is even possible – but rare. As elsewhere along the coast, summer is quite hot, and you’ll have lots of company on the beach.
In the Pantanal region you will find rainy/dry seasons, and if you plan to go, do so during the dry season of mid-April to late September. From October to mid-April, the wetlands receive tremendous rainfall, washing out roads and making travelling a nightmare.
