The best time to visit South America is from April to May or September to November. These months represent the fall and spring seasons in the Southern Hemisphere. The continent is vast, with an incredible number of microclimates and geographical regions that result in different weather patterns and changing temperatures throughout the year.
By visiting in fall or spring, you have the best opportunity to enjoy comfortable temperatures, whether you are traveling the Inca Trail in Peru, looking for the perfect beach in Colombia, or hoping for fewer crowds in Brazil’s Rio de Janeiro.
The summer months of December to February are popular for visiting coastal destinations across South America, but can result in larger crowds, hot weather, and high humidity, while winter can be very cold across the southern and mountainous countries, especially in destinations like Patagonia. Autumn and spring are considered shoulder seasons across South America, making them more comfortable for any type of trip.
