The best time to visit Iguazu Falls
Timing your visit to Iguazu Falls can make the difference between a good trip and an extraordinary one. The difference between sweltering in oppressive heat and humidity surrounded by tour groups versus comfortably exploring near-empty trails is all about choosing the right month. I learned this firsthand when I visited in November and experienced ideal conditions. Here’s everything you need to know about when to visit these magnificent falls.
What month is best for Iguazu Falls?
The Iguazu Falls are situated in the tropical rainforest of Iguazu National Park. This means the climate here is hot and humid, with an abundance of rain, depending on what time of year you go. There are two factors to consider when deciding on the best month to visit Iguazu Falls. One is the weather. The other is the number of tourists likely to be visiting at the same time as you.
The rainy summer season is from October to March, with temperatures reaching a sticky 33°C. During these months, the level of the waterfalls is at its highest, so it attracts more local tourists. The drier and cooler winter season (10°C to 25°C on average) is from May to September.
The best time to visit Iguazu Falls is in the shoulder months between these seasons. So, from April to May or between September and October. It’s not as hot during these months and less rainy, so it’s more comfortable weather to visit. There will also be fewer tourists at this time.
Which days of the week are best for Iguazu Falls?
If you’re wondering which day to visit Iguazu Falls, Monday to Friday is best. This way, you’ll avoid the majority of tourists who visit at the weekend. Early morning is ideal to avoid crowds and heat. The parks open around 9am and arriving early ensures better photo opportunities and shorter queues for popular attractions like the boat rides.
What is the best time of day to see Iguazu Falls?
Early morning between 9am and 11am is the best time of day to see Iguazu Falls. You’ll avoid the intense midday heat, encounter fewer crowds and get better lighting for photography. I arrived at the Brazil side just after opening and had the Devil’s Throat walkway nearly to myself for the first hour. By midday it was packed with tour groups. The parks open around 9am on both sides.

Is it better to stay in Argentina or Brazil side of Iguazu Falls?
Choosing between staying on the Brazil or Argentina side is an important decision when planning your Iguazu Falls itinerary.
Staying on the Brazil side in Foz do Iguaçu has several advantages. The city has better infrastructure with more hotel options across all budget ranges, from backpacker hostels to luxury resorts. From here you have easy access to the airport, as well as plenty of restaurants and nightlife. Personally, I started on the Brazil side as I flew in from Rio de Janeiro.
Meanwhile, Puerto Iguazú on the Argentina side is a much smaller city with charming local restaurants and a laid-back vibe. Your accommodation here can be right within the national park boundaries. If you’re continuing your journey to Buenos Aires by bus, like I was, this side makes more sense.
On my two day Iguazu Falls itinerary, I combined both. On the first night, I stayed on the Brazilian side, then I crossed the border to Argentina for day 2. Doing it this way means you arrive at the airport, settle into your accommodation and start with the panoramic Brazilian experience, before exploring the more adventurous Argentina side the next day.
Getting to Iguazu Falls
Iguazu Falls is accessible from both Brazil and Argentina, and it also borders Paraguay. Both Brazil and Argentina have nearby airports and gateway cities to this natural wonder. Most international travellers fly into either Brazil’s Foz do Iguaçu Airport (IGU) which is 30 minutes’ drive from the city of Foz do Iguaçu, or Cataratas del Iguazú International Airport (IGR) in Argentina, which a similar distance from Puerto Iguazú.

You can also travel there by long distance bus from major cities like Buenos Aires.

My first sight of the Parque Nacional do Iguaçu was from the aeroplane. Just before arriving at the tiny Foz do Iguaçu airport, my flight from Rio de Janeiro circled the falls. This meant we could get a good look.
From high up you can see the heavily cascading water. It’s like you can almost hear it. White mist emanates from the green forests, like a steaming hole in the earth.
Travelling to Iguazu Falls from Buenos Aires
From Buenos Aires you can book a cheap flight to the Iguazu Falls which takes just under two hours. You can also catch non-stop bus from Buenos Aires which takes around 15 hours. I splashed out on a luxury seat and it was very comfortable.

From the Iguazú National Park entrance on the Brazil side of the falls, follow pretty trails along the forest wall. From here, you can view the scale and panorama of these impressive waterfalls, as well as the local wildlife.
At the end you come to what’s known as Devil’s Throat. This is a U-shaped chasm where you can truly appreciate the sheer power and volume of this natural wonder. The falls cascade over cliff, bouncing off the shiny rocks and thrusting into the water below. It generates a gauze of cool white mist that seems to cover everything.
There is a walkway, where you can venture out and get a good view of Devil’s Throat head on. Needless to say, you get wet, but on a humid day, it is refreshing.

Book a tour of the Iguazu Falls directly from your hotel in Puerto Iguazú.
This side of the falls offers an upper and lower trail. The lower trail leads to a boat launch station. Here, you wrap your belongings carefully in a waterproof sack, don your choice of swimwear or cagoule and prepare for a watery onslaught. The boat’s driver takes you through the damp mist to the base of the powerful falls. He then travels inside them.
As the white water slaps forcefully onto your head and all over you, you feel like you can no longer make out which way is up and it’s hard to even open your eyes. The second part of the falls we venture into is even more of a shock with the sheer weight of the water on top of us. What an experience. Drenched, exhilarated and happy, we took the rest of the walking trails to dry off.
From the upper trail you see so many astounding sights of this wondrous natural spectacle, from a variety of angles. If you’re like me, you’ll take so many photos, you’ll almost run out of space on your phone or camera.
How many days do you need for Iguazu Falls?
Unless you’re on an organised tour, a minimum of two days is essential for a complete Iguazu Falls itinerary. This allows you a full day to explore each side of the falls – this is really worthwhile as they are very different experiences. The Brazil side gives you spectacular panoramic views, while the Argentina side provides close-up encounters and thrilling adventures like the boat ride under the falls.
If you have more time, consider extending your stay to 3-4 days. This allows for additional activities such as a helicopter tour over the falls, exploring the surrounding rainforest trails and visiting the bird park.
I wouldn’t recommend trying to see both sides in one day. The border crossing between Brazil and Argentina can take time, and each side deserves proper attention to appreciate its unique perspective.
What to wear to Iguazu Falls
There are a few things you’ll need to pack and what to wear to make the most of your trip to the amazing Iguazu Falls.
In terms of clothes, a bathing suit is recommended for the boat trip where you go under the cascading water. Quick-dry clothing is essential as you’ll get soaked, especially on the Argentina side. I wore quick-dry hiking sandals, which were comfortable for walking along the forest trails and it didn’t matter if they got wet. A lightweight rain jacket will keep you comfortable during any sudden downpours. Overall, when deciding what to wear to Iguazu Falls, make sure it’s made of light fabric that will keep you comfortable in the humidity and dry quickly if it gets damp from the misty air.
With regards to other items to pack, a waterproof phone case is also a good idea to protect your device. Insect repellent is also crucial in this tropical environment. Don’t forget high SPF sunscreen as the tropical sun is intense, even through the forest canopy. The number one thing to take with you is your passport so you can cross the border and see the other side of these magnificent falls.
