The optimal times to visit Argentina

As the eighth-largest nation globally and one of the most geographically varied in South America, Argentina offers countless treasures.

Exploring this country means diving into vibrant cities, admiring breathtaking mountain lakes, traversing endless deserts, enjoying wetlands and plateaus, and wandering through stunning beaches and forests, plus unforgettable trips to world-famous wineries.

To fully enjoy your visit, keep in mind that the seasons will significantly influence what you can experience. Looking to trek to an Andean glacier? Or perhaps unwind by the sea?

How about kayaking through wetlands in search of remarkable birds? Catching a fútbol game or joining a tango class? Many of these adventures hinge on the time of year. Here’s our guide to when and where to immerse yourself in the beauty of Argentina.

The period from December to February is ideal for hiking in the South and enjoying nightlife in the North

These summer months mark the peak of both domestic and international tourism in Argentina. The heat and humidity in Buenos Aires drive locals to the Atlantic Coast’s beach destinations like Mar del Plata and Pinamar.

As a result, the cultural scene in the city may slow down, with fewer theater shows and live music performances, and some restaurants and businesses might close. You may also experience less congestion on the streets, in museums like Museo de Arte Latinoamericano de Buenos Aires (MALBA), along Corrientes Ave, and at other popular city spots that usually draw crowds.

In the North, temperatures can exceed 40ºC (104ºF). At Iguazú Falls and Iberá National Park, the heat and humidity become nearly unbearable, while the arid Northwestern provinces like Salta and Jujuy experience intense daytime heat but cool off significantly at night.

During this season, Patagonia’s weather is pleasant, making it perfect for hiking, camping, and enjoying the scenery. Expect elevated prices for flights and accommodations, particularly in popular spots like the stunning Lake District town of Bariloche and the renowned trekking destination of El Chaltén, along with increased crowds at main attractions.

In Ushuaia, located in Tierra del Fuego, temperatures reach their warmest, often surpassing 10ºC (50ºF); summer is the ideal time for hiking and sightseeing.

There are also significant celebrations throughout the country. In Gualeguaychú, a week-long Carnaval takes place in February. Meanwhile, Córdoba hosts two famous festivals in the small town of Cosquín: Cosquín Rock and Cosquín Folk Festival.

The optimal times to experience Buenos Aires are from March to June and September to November.

Spring (September to December) and autumn (March to June) are perfect for exploring Buenos Aires. The weather is pleasant, the city is lively, and it’s not yet overwhelmed with tourists.

During the low season, you’ll find lower accommodation and travel costs along with high availability. Since locals are around, expect restaurants to be bustling (make reservations in advance, particularly at popular spots like the Michelin-starred parrilla Don Julio and the exceptional Anchoita, which sources from its own farm and collaborates with local producers while offering one of the country’s finest wine selections).

November marks the arrival of jacaranda blossoms, which adorn the streets of Buenos Aires with their striking purple hues. Additionally, in April, the renowned BAFICI (Buenos Aires Film Festival) showcases outstanding Argentine and international cinema.

From late February to early April, Mendoza's Vendimia – the grape harvest festival – presents a fantastic chance to explore the region’s incredible wineries. Be cautious: accommodation demand skyrockets during this time, significantly increasing prices, so make sure to book your stay well ahead.

Mendoza experiences relatively mild temperatures from mid-September to June, making a visit to its numerous vineyards worthwhile even outside of the Vendimia season.

In Patagonia, Tierra del Fuego, and southern Argentina, the weather remains fairly mild (around 20ºC/68ºF), especially in March and November, offering a great opportunity to visit during a less crowded season.

To the north, Iguazú and Iberá are a bit cooler and rainier, with temperatures hovering around the mid-20ºCs to low-30ºCs (68 to 86ºF). This time of year is less crowded and ideal for visiting.

Similarly, the Northwestern provinces of Salta and Jujuy experience milder temperature variations and a calmer atmosphere, making it a perfect time to enjoy the stunning views of the Hornocal and the historic town of Cachí.

July and August are ideal for skiing in the South while also visiting Iguazú and Iberá in the North.

While winters in Buenos Aires aren't particularly severe – snow is quite rare – the shorter days and chilly temperatures (around 5 to 15ºC/41 to 59ºF) can make the city feel uninviting.

Consider seizing the peak skiing season by visiting Cerro Castor ski resort in Tierra del Fuego, Cerro Catedral near Bariloche, and Las Leñas in Mendoza for exceptional skiing experiences. The last three weeks of July see the highest demand, coinciding with winter vacation for Argentine schools, which can increase prices at ski resorts across the country.

There’s also a lot of excitement off the slopes. In Ushuaia, celebrate the Fiesta de la noche más larga on June 21, where the city comes alive for the longest night of the year. Meanwhile, Bariloche’s Rapa Nui chocolate shop offers its famous Franui (chocolate-covered raspberries) alongside a wide array of award-winning chocolates.

If cold weather isn't your thing, consider heading north to Iguazú and Iberá National Park, known for their stunning waterfalls and unique wildlife, which are always warm and inviting. Jujuy and Salta may be chillier at night, but they stay quite mild during the day, making attractions easily accessible just like in spring and fall.
