May is the best-kept secret for exploring southern Brazil. With 60 to 70% less traffic than in July, you'll enjoy quieter roads and less crowded attractions. In addition, May is the month of wine harvest festivals in Caxias do Sul, providing an immersion in the local wine culture. But the highlight is the mist in the canyons of Aparados da Serra, which creates breathtaking landscapes, perfect for memorable photographs. Local guides confirmed to 1Weather that this magical window closes in mid-June, so plan your trip in advance!
