Argentina is a large country with varied climates and topography ranging from the tropical north to the sub-Antarctic south. That variation in climate and geography allows it to be a good destination to travel at any time of the year, while the best time to visit mostly depends on what you want to do during your trip and which places you would like to go to. Plan your trip with this seasonal guide on the best time to visit Argentina, and don’t forget to secure your Argentina visa for a smooth and enjoyable journey.

Seasons in Argentina

Argentina is in the Southern Hemisphere, hence, its seasonality is precisely opposite to that of the United States and most of Europe in the Northern Hemisphere. In other words, during the time period when the United States and Europe are in their cold winter months, Argentina is having its hot summer months and vice versa. 

Here is a fast look at Argentina's seasons:

Understanding the seasonal layout of Argentina will help in planning a visit, especially for those who want to experience a certain climate or activity that could only be best offered during specific times of the year. Here is a breakdown of the best times to visit based on the different parts of the country.

Buenos Aires is a city that can be visited all year round, but the best seasons are spring and autumn, where the temperatures are gentle. During these months, the temperature remains pleasant, varying from 15°C to 25°C during the day, ideal for walks in urban parks, historic sites, and barrios such as Palermo, Recoleta, and San Telmo.

Summer, from December to February, is very hot, with temperatures over 30°C for most days; winter, from June to August, is cool, rarely below 10°C.

Patagonia: Best in Summer 

Patagonia, including Andes Mountains, glaciers, and national parks, has the best weather during the summer in Argentina: warmly ideal for hikes, glacier treks, and spotting wildlife. A trip to El Calafate may provide visiting the famous Perito Moreno Glacier, while El Chaltén usually enjoys clear skies at this time of year for treks in Los Glaciares National Park.

Iguazú Falls: Best in Fall and Spring

Iguazú Falls is one of the most spectacular waterfall systems in the world and best visited during the shoulder seasons of fall and spring. During these months, the weather remains warm yet not unbearably hot, with less humidity compared to summer. The falls are especially good after the summer rains when the water flow is at its peak.

Summer is a sweltering 35°C (95°F) hot and humid, between December and February, and thus less pleasant due to the excessive heat. It is also the time when the falls are at their highest intensity. Winter weather cools down; however, this possibly means lower water levels.

Top Fall/Spring activities:

– Visit Iguazú Falls on the Argentine and Brazilian side.

– Take a boat ride into the mist of Devil's Throat.

– Hike the trails in Iguaçu National Park to encounter their wildlife, including toucans and monkeys.

Mendoza: Best in Fall

Mendoza is the Argentine wine country and is especially pretty in fall when the vineyards are golden and temperatures are mild. March also features Vendimia Harvest Festival, a rowdy celebration of the wine harvest, including parades with music and tastings. The temperature fluctuates between 15°C and 25°C, thus providing excellent conditions for a tour in vineyards and outdoor sports like hiking or biking through the beautiful valleys.

Summers in Mendoza are usually hot, though for all the wine lovers, it is not so bad a period. The winters, though, are cooler and just perfect to ski in the Andes nearby.
