May in Argentina is a shoulder season, bridging the gap between the hot summer months and the cooler winter period. For travelers, this means fewer crowds and often more reasonable prices, but it also brings varied weather conditions depending on the region you plan to visit. Understanding the average temperatures you can expect across Argentina in May is crucial for packing appropriately and planning your itinerary effectively. Let's dive into what you can expect temperature-wise in different parts of this diverse country.

Regional Temperature Variations

Argentina is a vast country with a diverse climate that ranges from subtropical in the north to subpolar in the south. In May, this variance is particularly noticeable, so it's essential to understand what to expect in specific regions:

Buenos Aires and the Pampas

The Buenos Aires and Pampas region experiences a mild autumn climate in May. You can expect average temperatures ranging from 12°C to 18°C (54°F to 64°F). The humidity starts to decrease compared to the summer months, making it a more comfortable time to explore the city and surrounding areas. Evenings can be cool, so packing a light jacket or sweater is advisable. Rainfall is moderate, so it's a good idea to bring an umbrella or raincoat.

Patagonia

Patagonia in May is entering its colder season. The average temperatures range from 2°C to 10°C (36°F to 50°F). In the southern parts of Patagonia, such as Ushuaia and El Calafate, temperatures can drop below freezing, especially at night. Snowfall is possible, particularly in the higher elevations. If you plan to visit Patagonia in May, be prepared for cold, windy conditions and pack warm layers, including thermal underwear, a heavy coat, gloves, and a hat. Despite the cold, the autumn colors can be stunning, and there are fewer tourists than in the peak summer months.

Andes Region

The Andes region, including destinations like Mendoza and Salta, also experiences significant temperature variations depending on altitude. In Mendoza, known for its vineyards, the average temperatures in May range from 8°C to 17°C (46°F to 63°F). It's a pleasant time to visit as the summer heat has subsided, and the fall foliage adds to the scenic beauty. However, if you plan to explore higher altitudes, such as the Aconcagua area, be prepared for much colder temperatures and the possibility of snow.

Salta and the northwest region tend to be milder than Patagonia but cooler than Buenos Aires. Average temperatures range from 10°C to 20°C (50°F to 68°F). This region is known for its stunning landscapes, including deserts and colorful rock formations. It's a great time to visit as the daytime temperatures are comfortable for hiking and outdoor activities, but evenings can be cool, so layers are recommended.

Iguazu Falls

Iguazu Falls, located in the subtropical northeast of Argentina, maintains a warmer climate in May compared to the southern regions. Average temperatures range from 18°C to 25°C (64°F to 77°F). The humidity remains relatively high, and rainfall is still frequent, so be prepared for wet conditions. Despite the rain, it's a good time to visit as the crowds are smaller than in the peak summer season. Lightweight, breathable clothing and rain gear are essential.
