Plan wisely if you're considering visiting Iguazú in July: during the second half of the month, the region is packed with Brazilian and Argentine tourists on vacation. Luckily, the weather is generally sunny, dry, and comfortable throughout the month, whether you're battling crowds on the hiking trail or enjoying views of the cascades in relative peace. Read on for more about what to expect at Iguazú in July with this monthly guide.

Weather

July is the middle of winter in Argentina and Brazil, where Iguazú Falls are located. It doesn't look or feel like it, though, to travelers from the northern hemisphere: the season brings comfortable temperatures, sunshine, and minimal rainfall to the region.

Naturally, the days are shorter, but it's one of the only ways to detect that it's winter. Expect highs in the mid-70s and lows dipping into the 50s after nightfall with moderate humidity levels. Bring a jacket and sweater, but you probably won't need rain gear, as July sees only six days of rain during the month, on average.

Crowds & Costs

Planning travel to Iguazú around this time of year? Consider July two separate months: in terms of crowds and costs, the first two weeks of July are completely different than the second two weeks. That's because it's winter break at schools in Argentina and Brazil, and lots of families plan to travel within this time period, taking advantage of both vacation days and flight promotions and packages.

The dates vary slightly each year, and across schools (and countries), but generally speaking, you'll be better off visiting Iguazú in the first and second weeks of the month, when crowds are fewer in the parks and hotel rates are reasonable (or even low) while school is in session. During the last two weeks of the month, all bets are off. Hotels are booked out well ahead of time, rates soar, the parks fill up with visitors, and you'll probably need dinner reservations in town, as well. 

What To Do

If you're visiting during the first half of the month, especially during the week, you'll be able to enjoy the parks in relative peace and quiet. Hike the catwalks around the waterfalls' cascades, get on a boat to see the falls up close on the Gran Aventura excursion, bird-watch in the forest as you make your way toward viewing platforms and lookout points where you'll enjoy relatively unobstructed views of key natural attractions like Bossetti Jump and Garganta del Diablo.

On the other hand, if you're visiting in the second part of July—one of the busiest times of the year in Iguazú—you'll want to strategize a bit more to get the most out of your trip.

Consider the following tips: first, try to be one of the first people at Iguazú National Park in the morning, then proceed directly to the train station, where you'll catch a ride most of the way to Garganta del Diablo. (The idea is to be one of the first people at the lookout point: this popular destination gets very crowded later in the day with tourists.) Second, book well ahead of time if you want to go on a boat trip or a nocturnal hike.

Third, get off the beaten path with a quiet hike on Macuco Trail, where far fewer visitors venture. You'll spend several hours on the round-trip journey to a single waterfall: take a picnic and lots of water, as there aren't visitor services along the trail.

What To Look For

Toucans, hummingbirds, doves, cuckoos, parakeets: these are just some of the more than 430 species of birds that live in the parks' jungles. They're generally active and easy to spot at this time of year, alongside more than 70 species of mammals, from capuchin monkeys swinging through the trees to pestering coati (a raccoon-like animal that has its sights set on your sandwich, energy bar, or any other food item) to larger-than-life lizards and the elusive jaguar.

Since the level of the river is lower in winter than in summer, you may find that the views of the waterfalls are somewhat less dramatic than what you'd see in summer. This is good news, though, for hikers and families traveling with children: catwalks and trails stay dry (they often get slippery in other seasons) and boat tours run without interruption.

Ask at the Visitors Center about going on the Ecological Tour raft ride, which departs from the Garganta del Diablo train station: the journey is partly about observing flora and fauna, and your guide can help you spot plants, trees, birds, and animals you might otherwise miss.

Events & Activities

Walks in the Moonlight: Iguazú National Park offers guided nocturnal tours on five evenings each month. The schedule depends on the lunar calendar.
