Best time to visit Iguazu Falls in Brazil
With the temperature at Iguazu Falls remaining reasonable throughout the year (reaching a maximum of around 30°C and a minimum of about 10°C), the main factor that decides when people should travel is rain. From December to March, the weather is at its hottest and rain falls pretty consistently. This shows the falls at their most majestic but grey skies and suffocating humidity might hamper the experience somewhat.
During the winter months the falls are blessed with bright blue sky and much milder temperatures, which make a big difference when visiting from the Brazilian side. Seeing the falls from this side is less about getting up close and personal with the water and more about breathtaking panoramic views of the falls. For photographers, the Brazilian side offers some truly spectacular Kodak moments that are best snapped with blue skies. The lower water level that comes with the dry season also means that trails and activities are likely to functioning and open as normal.
Generally, people agree that the shoulder months of March, April and September are the best times to visit because, although the falls aren’t at peak flow, they are more aesthetically pleasing thanks to the clear skies and rocks peeking through the cascades.
