Brazil’s enormous size and range of climates mean the best time varies by region. Generally, December–March is peak summer in the southern hemisphere, perfect for beach life in Rio de Janeiro, Salvador, or Florianópolis. Carnival—usually in February or early March—adds a festive pulse but significantly raises prices and hotel demand. The Amazon region experiences a rainy season (December–May) and a drier period (June–November), though it’s hot and humid year-round. The Pantanal wetlands are best visited in the drier season (May–September) for wildlife spotting. Southern Brazil can become cooler in winter (June–August). If you aim to see multiple regions, consider traveling from July to early October, when conditions across the country are relatively pleasant and crowds a bit thinner outside major festivals.
