Brazil: when to go?
tropical humide climate
Brazil features a humid tropical climate dominated by two distinct seasons: the dry season (April to September) and the rainy season (October to March). Temperatures remain pleasantly warm year-round, ranging between 22°C and 32°C depending on the region. The dry season offers ideal conditions with generous sunshine, rare rainfall and more comfortable humidity levels. It's the perfect time to explore Rio, visit Iguazu Falls or venture into the Amazon. Conversely, the Southern Hemisphere summer (December to March) corresponds to the rainy season with intense tropical showers, high humidity and heavier temperatures. Though spectacular, this period can complicate travel and outdoor activities. For an optimal trip, choose the dry season which combines favorable climate, lush nature and ideal conditions for all tourist activities.
