The weather all over the country maintains the same pattern. So if it’s hot in Sao Paulo, it’s likely to be hot in Salvador as well. The tourist seasons too remain the same. Since Brazil is located in the Amazon basin, temperatures don’t go too high or drop too low; any time is a good time!
Before you plan an off-season travel, check in with the places you’re planning to visit. Many-a-times, tourist attractions are shut during the off-season for repair and maintenance. You don’t want to travel so far only to end up standing in front of a ‘closed’ sign.
