Best time to visit Argentina

Given the immense size of Argentina, the weather in the country varies hugely from one region to another. When planning a trip, it’s important to think about what the seasonal weather will be like in the region you’re planning to visit, so you can try to see each area of the country at the optimal time of year. Of course, the best time to visit Argentina depends on what areas you want to explore and what you plan to do. Here's our guide to the weather in Argentina.

When's the best time to visit Argentina

The best time to visit Argentina largely depends on the regions you plan to explore, as the country's vast size means weather can vary significantly from north to south.

For Buenos Aires and the Pampas, the most pleasant times are spring (September to November) and autumn (March to May), with mild temperatures and fewer crowds. During these seasons, Buenos Aires enjoys temperatures ranging from 15°C to 21°C (59°F to 70°F), perfect for strolling through the city's vibrant streets and enjoying outdoor cafes.

Patagonia is best visited during the Southern Hemisphere's summer months, from December to February, when the weather is mildest and hiking trails are most accessible. Temperatures during this time can vary widely, from cool 5°C (41°F) nights to warmer 24°C (75°F) days, depending on the exact location and altitude.

The Iguazu Falls, in the northeast, are spectacular year-round, but the flow is most impressive during the rainy season from December to March. However, for those looking to escape the heat and enjoy clearer skies, May to September offers cooler temperatures, around 15°C to 25°C (59°F to 77°F), and less humidity.

For wine enthusiasts looking to visit Mendoza and the wine regions, March to May (fall) is ideal. The grape harvest takes place, and the landscape turns into a palette of red and orange hues. Temperatures during this period are comfortable, ranging from 8°C to 22°C (46°F to 72°F), perfect for wine tours and outdoor dining.

Visit Argentina in winter

The winter months of June, July and August are the best time to travel to the Andean ski resorts, but blizzards can cut off towns in Patagonia and many places close from Easter through to October, so it’s not a good time to tour the southernmost region. Temperatures in the north of the country should be pleasant at this time of year, although Buenos Aires can come across as somewhat bleak in July and August, despite a plethora of indoor attractions.

Visiting Argentina in June

The usually hot and humid climate of the north of Argentina is much milder during winter, so why not use June to explore this scenic region?

The best time to visit Argentina per region

Discover the optimal time to visit Argentina by region, from the bustling streets of Buenos Aires to the remote glaciers of Patagonia. Each area offers unique experiences, best enjoyed at specific times of the year.

Weather in Patagonia

Anyone seeking an adventurous trip can consider the lakes, mountains and glaciers of Patagonia –the ideal region for an off-the-beaten-path experience.

This vast wilderness stretches across the south of Argentina and into neighbouring Chile, covering an incredible 400,000 square miles. It encompasses lakes, mountains, glaciers and coast. During the summer months (December to March) temperatures reach 15-20°C and the rainfall is at its lowest, making this the optimum time to visit Patagonia. While in the winter months (June to August), the temperature drops below freezing and many visitor attractions close.

Most of the country enjoys hot, humid summers and cold, dry winters, but in Patagonia, the weather conditions are reversed with the summer providing hot and dry conditions and increased rainfall during the cold winter months - making this region a unique destination in Argentina. The best time to visit Patagonia would be during the summer season, as ice and unexpected weather can make this scenic destination treacherous during winter. The mild weather of the summer months offers the perfect opportunity for discovering the beautiful Patagonian landscape, as this is the time of year when national parks and glaciers are often easily accessible and hiking conditions are good.

Discover more about this seemingly endless landscape that has inspired writers and adventurers with its epic scenery in our Patagonia Travel Guide.

Weather in the Pampas and central region

Famed for its great nightlife, passionate locals and love of tango, Buenos Aires is a must-visit for anyone heading to Argentina.

Of course, Buenos Aires is only a small part of the central region. The pampas – a place of big skies and fertile, lush grasslands where cattle graze – seems to stretch as far as the eye can see and beyond. The weather in the Pampas is hot and humid in summer (Dec-Feb) and cool and dry in the winter (June-August). With cooler, less humid days, Spring (Sep-Nov) is the best time to visit the Pampas or Buenos Aires.

Weather in the Andes

The world’s longest mountain range, this magnificent set of peaks is a big draw for travellers and passes through seven South American countries. It can be a treacherous place to climb or hike if you’re not experienced, but under the right weather conditions, the Andes is an incredible region to visit.

The weather in the Argentine Andes dips below freezing during the winter and, of course, the higher you get the quicker the temperature can drop. The best time to visit the Andes is during the spring and summer months when the warmest weather averages 20°C; a far more comfortable temperature for walking and exploring.

Argentina lays claim to the highest peak outside of the Himalayas, the 6,959-metre-high Aconcagua – definitely not a peak that should be attempted without serious advance planning. Exploring the Andes region might well mean venturing across the border into Chile.

Weather in the north

Expect heat and humidity on a trip to the north of Argentina. This subtropical zone is home to wetlands, salt flats and even an area of rainforest where you’ll find the awe-inspiring Iguazú Falls.

In the summer, temperatures can reach above 35°C and it can be uncomfortably humid. The northwestern region of Argentina gets nearly 500mm of rainfall a year, that gives you an idea of the humidity to expect when visiting this beautiful yet humid part of the country. The Iguazú falls are popular with locals and tourists alike – so try to avoid the main holiday periods of January, Easter week and July – September to December and February to May will see good weather and fewer crowds. ,

You’ll have the chance to explore breathtaking cloud forests and take in Spanish colonial architecture during a trip to this region, known as the birthplace of Argentina. Find out more in our guide to the Northwest of Argentina.
