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.
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.

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.
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? Winter arrives, bringing cooler temperatures, with average highs around 17°C (63°F). The natural landscape is full of unusual geographic formations, from charcoal lava flows to sparkling-white salt flats and lush jungle terrain, so head north for a trip through Argentina’s stunning northern scenery.

Winter in Argentina is at its coldest during this month, with average highs around 15°C (59°F).
In Argentina’s capital, August is a cold and quiet time of year when many attractions shut down for the winter. However, Buenos Aires comes to life during the world-famous Tango International Festival. Expect two weeks of free performances, concerts and classes, and the all-important international tango championship. Similar to July, with cold temperatures persisting, the temperature in Argentina in August averages around 16°C (61°F).

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.
