It’s late autumn in Argentina with shorter days and cooler weather. This is a great time to visit Iguazú Falls, the northwest desert, and wine region of Mendoza with fewer crowds where you can enjoy the gorgeous foliage and spectacular landscapes in peace. Read this monthly guide to learn more.


Due to Argentina's location south of the equator, this is the month of late autumn, which means different things depending on where you travel. Buenos Aires will see highs in the mid-60s with less rainfall than previous months. In Iguazú Falls, along the Brazilian border, you'll get high-70s with slightly increasing rain, while in Mendoza, you'll see temps in the mid-60s with hardly any rain at all. 

If you don't mind the chilly and potential wet weather, this can be a quiet time to visit Patagonia. Winds are not quite as strong as they are in the summer and the forests can offer the last peeks of brightly-colored fall foliage. Keep in mind that daily highs fall into the mid-40s with lows in the 30s making brisk conditions for exploration. Not only that but rain showers are more likely, while daylight hours are shortening leading up to winter.

Crowds & Costs

May makes up Argentina's shoulder season without the threat of Easter crowds (like April). That makes this month a great time to take advantage of consistent off-season pricing. In other words, both hotel rates and crowds are at some of their lowest numbers of the year.

Where to Go

It's a wise idea to stay north of Patagonia this time of year if you like nice weather for sightseeing and outdoor adventures. In Buenos Aires, for instance, you count perfect weather for full days of walking and sightseeing through a variety of neighborhoods.  

For wine lovers, there are 1500-odd vineyards in the Mendoza region, which mostly offer the Argentine Malbec. A few out-of-the-ordinary wine-themed attractions exist, like the wine wellness retreat at Cavas Wine Lodge where you can get a facial scrub made from crushed grapes. 

You can also head the Calchaquí Valley for some epic day-trips based out of Salta. For instance, travel along National Route 68, arriving in the village of Cafayate, which is also internationally recognized for its wine production. Also in the area is the village of Purmamarca, where you'll find the famous Cerro de Siete Colores (Hill of the Seven Colors), as well as salt flats, and jaw-dropping desert landscapes with few tourists.

What To Do

Those in search of urban culture will love exploring the capital this time of year for a range of tango performances, steakhouses, dazzling colonial buildings, and neat cocktail bars including hard-to-find speakeasies. 

This is also the best season to visit Argentina's famous wine-growing region for tastings, local festivals, and vineyard tours, plus a wealth of options ranging from cycling to horseback riding in the foothills of the Andes. In other words, the region is filled with plenty of outdoor activities to choose from. Here's more on Argentina's best wine regions

If heading northwest to Salta, you can spend days driving through canyons and mountain passes while visiting villages that have a relaxed vibe, friendly locals, hiking trails, and spectacular mountain vistas.  

This is also a great time to explore Iguazú National Park where you can take a full-day guided excursion that involves traversing three circuit routes around the falls, each offering exceptional vantage points from which to view this magnificent natural wonder including hundreds of waterfalls and tropical foliage. Bike and boat tours are also available.
