Iguazu Falls Argentina Travel Guide
Climate Patterns Throughout the Year
Summer (December to February): This period brings the hottest and wettest conditions. Temperatures typically range from 28 to 35°C (82-95°F), sometimes exceeding 40°C (104°F). Expect high humidity and frequent, intense thunderstorms. These storms often feature heavy rain in short periods rather than continuous downpours. The falls usually present their most powerful flow during these months due to increased water levels from the rain. This creates a truly impressive display of water volume and force. Prepare for strong sunshine and humidity, which might make physical activity feel more strenuous. Autumn (March to May): Temperatures begin to cool during autumn, averaging a more comfortable 20-28°C (68-82°F). Rainfall lessens compared to summer, but consistent precipitation still occurs. The vegetation stays lush and green, creating a beautiful backdrop for the falls. Many visitors find this period agreeable for exploring the park's trails, as the extreme heat of summer has lessened. The air feels lighter, making walks more pleasant. Winter (June to August): Winter brings the mildest temperatures, typically ranging from 15-25°C (59-77°F). Humidity levels drop, and this period is generally drier than the summer months. Many consider winter the most comfortable time for walking and spending extended periods outdoors, as the weather presents less challenge. While water levels might be slightly lower than in peak summer, the falls retain their spectacular nature. Reduced mist also sometimes provides clearer views for photography. Spring (September to November): Temperatures climb again in spring, averaging 20-30°C (68-86°F), and humidity starts to increase. Rainfall also picks up during these months. This season balances rising temperatures and flourishing nature, creating a visually rich experience.
The Iguazu region does not experience monsoons or hurricanes. However, heavy thunderstorms, notably common in summer, can cause temporary path closures within the park if water levels become excessively high or if lightning poses a risk. Park authorities prioritize visitor safety and will close walkways like the Devil's Throat if conditions become unsafe.
Intense heat in summer also means taking precautions against dehydration and sunstroke. Drink plenty of water and seek shade often.
