The best time to visit Argentina is from September to March. These warm spring and summer months are best for enjoying the great outdoors in Patagonia and the Lake District . In September Cape Horn cruises set sail from Ushuaia and it’s one of the best times to visit Buenos Aires for warm spring weather, without the crowds.
Argentina is a long thin country with varying climates across different regions. Tropical Iguassu Falls is close to the equator and feels warm, even during the winter months of June to September. Whereas, Ushuaia, the southernmost city in the world, and Calafate and Chalten in Patagonia experience bitterly cold conditions at the same time of year.
Choosing the best time to visit really depends on what you want to do, whether that’s enjoying the Harvest Festival in Mendoza in March or hiking in Los Glaciares National Park in June. In our essential Argentina climate guide we'll explain what the weather will be like each month and which region is the best to visit at that time, and what you can do there.
Argentina Month-by-Month Weather Guide
Argentina is a large country filled with diverse landscapes from rainforests to glaciers – and everything in between. Throughout the year the changes in the climate can dramatically affect the different regions and the activities you can do there. To help you plan the best time to visit Argentina we’ve put together the ultimate climate guide below, letting you know what to expect each month.
January in Argentina
January is one of the warmest months in Argentina with temperatures in Mendoza, Buenos Aires and Iguazu Falls reaching the mid 30s°C (90s°F). Although January is not the wettest month, Buenos Aires and Iguassu can experience daily rain showers.
February in Argentina
February is typically Argentina’s warmest month, particularly in the cities where it can start to feel stifling. February is also often the rainiest month in Argentina too. In the south of the country, where temperatures are always cooler, it’s a wonderful time of year to explore Patagonia and escape the heat in the north. Expect temperatures to peak in Buenos Aires at around 32°C (89.6°F).
March in Argentina
March signifies the end of the summer and can be a great month to travel to Argentina. The north of the country in areas like Mendoza and Buenos Aires are starting to cool a little while Calafate and The Lake District aren’t too cold yet, averaging around 12°C (53.6°F), and conditions are still good for hiking.
April in Argentina
By April the shift to a cooler climate is more pronounced. Mendoza’s hot season ends with midday temperatures sitting in the low 20s°C (70s°F), great for hiking and outdoor activities. By mid-April Cape Horn cruises cease as the weather is cold and sea conditions are very rough and outdoor activities around Ushuaia’s Tierra del Fuego and Los Glaciares national park will require extra time and planning, due to potential adverse weather conditions.
May in Argentina
The mercury continues to drop in May as Argentina creeps steadily towards winter. May can also be a wet month in the Lake District. May is a good month to visit the Puna, Salta or Ibera Wetlands, which are cool (compared to summer). Buenos Aires is pleasant at around 17°C (64°F), although evenings are starting to feel chilly.
June in Argentina
June is one of Argentina’s winter months and although tropical Iguassu Falls remains balmy at 22°C (72°F), you will need to pack a jacket to visit Buenos Aires with temperatures of around 15°C (59°F). Those looking to hike or enjoy boat trips in Patagonia will now need to wait until the spring as the snowy season has started.
July in Argentina
July, very similar to June in terms of temperatures, is another cold month in Argentina, it’s now midwinter and the south of the country experiences the lowest temperatures, getting down to around 5°C (41°F). For those interested in snow activities now is a good time to visit the Lake District.
August in Argentina
August is another winter month with cool conditions across the country. That being said, Buenos Aires and Mendoza experience slightly milder daytime temperatures, in comparison to July, of around 18°C (64°F) and the days are typically clear and sunny.
September in Argentina
Spring begins in September, a beautiful time to venture to northern Patagonia where spring flowers start to bloom, however the weather conditions in southern Patagonia can be unpredictable and not great for longer hiking trails. September is one of the best times to go to Buenos Aires, Mendoza and the north. This is also one of the driest months for the Iberá wetlands so wildlife can be easy to spot congregating around the diminished water sources.
October in Argentina
October is the best month to see wildflowers in full bloom in Patagonia. For those looking to hike in the Los Glaciares National Park, it’s best to wait until November. But, for the Lake District and sightseeing to the Perito Moreno glacier, October is a good time of year.
November in Argentina
November is a great month to visit Argentina with warm weather, around 31°C (87.8°F) in Buenos Aires. The hiking season in Patagonia begins and it’s a good time to visit to skip the busy crowds that travel in December for the Holidays. November is a hot, wet month for Iguassu Falls and the water levels are high, so the falls themselves are impressive as they cascade into the river below.
December in Argentina
December is the height of summer in Argentina and a wonderful month to visit for warm weather, expect highs of 31°C (87.8°F). However, it can get very busy. If you plan to travel towards the end of the month you will need to book accommodation up to a year in advance.
The Best time to Visit Buenos Aires
The best time to visit Buenos Aires is between September to December which brings pleasant temperatures, fewer crowds and sunny days. This is the perfect season to enjoy what the city is best known for – history, architecture and walking food tours.
During the summer months starting from December to March the city buzzes with life, however it can get quite hot and uncomfortable. Tango shows take to the streets and some choose to enjoy days outside of the city in San Isidro or the Tigre Delta.
The colder winter months of July and August are good months to visit Buenos Aires, as although temperatures drop, there’s typically less rain and clear skies.
