When Is the Best Time to Visit Argentina?
The best time to visit Argentina depends on the regions you want to explore. December to February is the main season for hiking in Patagonia, while September to November and March to May bring milder temperatures that are particularly good for Buenos Aires, Mendoza and Iguazu Falls.
Argentina stretches for more than 4,300 kilometres from north to south, so conditions vary considerably. Buenos Aires has hot summers and cooler winters, the north remains warmer throughout the year, while temperatures become noticeably cooler as you travel towards Patagonia and the far south.
If you want to combine several regions, spring and autumn are particularly good times to travel. Summer brings longer days and the widest choice of outdoor experiences further south, while winter is a good time for exploring the north or skiing in the Andes.
There is plenty to consider beyond the weather too, from Mendoza’s grape harvest to seasonal access in Patagonia. Below, we take you through the year and explain what to expect, helping you choose the right time for your Argentina Holiday Ideas.

December to February
Summer and Peak Season
December to February is summer in Argentina, but the season feels very different depending on how far south you travel. Buenos Aires is at its hottest, with warm evenings and high humidity, while Mendoza is typically hot and dry, with the vineyards approaching harvest towards the end of summer.
Further south, this is the main season for exploring Argentinian Patagonia and the Argentinian Lake District, although the weather differs considerably between the two. Around El Calafate and El Chaltén, expect cool summer temperatures, long daylight hours and plenty of wind, with conditions that can change quickly. Around Bariloche and the Lake District, summer is generally warmer and drier, with daytime temperatures often around 20°C and cooler evenings.
The long days give you more time outdoors, from walking the trails around El Chaltén and seeing the glaciers of Los Glaciares National Park to exploring the lakes and mountains around Bariloche. In southern Patagonia, layers and waterproofs are essential even in January. Strong winds, rain, sudden drops in temperature and occasional snow are all possible.
March to May
Autumn and Harvest Season
March to May is a particularly good time to explore several parts of Argentina. Buenos Aires is more comfortable after the heat of summer, with plenty happening across the city. April brings the BAFICI film festival, while the milder days are well suited to exploring neighbourhoods, parks and markets on foot.
In Mendoza, the grape harvest is the main event. Vendimia runs from late February into early April, with March at the heart of the celebrations. Vineyards are busy with the harvest, wineries host tastings and events, and it’s a fascinating time to spend a few days in wine country or stay at one of the estancias in Argentina.
March is also a good time for Patagonia, with walking trails still accessible and milder conditions around El Chaltén and El Calafate. Iguazu Falls and the northwest around Salta and Jujuy are also worth considering as temperatures begin to ease, making autumn one of the most versatile times to travel around Argentina.
June to August
Winter in Argentina
June to August is winter in Argentina, and where you travel makes a big difference. This is ski season in the Andes, with Bariloche and Cerro Catedral among the main places to head for the slopes. Further south, Ushuaia has a long winter season too, with skiing at Cerro Castor as well as snowshoeing, dog sledding and other winter activities.
If you prefer warmer weather, head north. Iguazu Falls remains pleasantly warm during winter, with lower humidity than the summer months, making it a comfortable time to explore the walkways and surrounding forest. Salta and Jujuy are another good choice, with generally dry days for exploring the colourful landscapes and mountain towns of northwest Argentina, although nights can be cold.
Winter is less suited to a classic trip through southern Patagonia. Days are short, snow and ice can affect walking routes, and some hotels and excursions around El Chaltén close for the season. Unless you’re specifically travelling for the snow, we’d save this part of Argentina for the warmer months.
September to November
Spring and the Start of the Outdoor Season
September to November is a lovely time to travel in Argentina. Winter is giving way to warmer days, the countryside is becoming greener and the intense heat of summer is still to come.
Spring is particularly noticeable in Buenos Aires. People return to the parks, cafés spill outdoors again and, by November, thousands of jacaranda trees burst into flower, covering parts of the city in purple. It’s one of our favourite times for 48 Hours in Buenos Aires, when you can comfortably explore much of the city on foot.
Elsewhere, spring marks the return of the outdoor season. Vineyards are green again, mountain routes become more accessible and longer daylight hours gradually open up more of the country as November approaches. It’s a good all-round choice if you want an active holiday without travelling at the height of summer.
Best Time to Visit Buenos Aires
Buenos Aires is at its best from March to May and September to November, when temperatures are comfortable enough to spend much of the day exploring on foot. It’s a city that rewards time outside, walking between neighbourhoods, stopping at cafés and markets, and staying out for dinner without the heat and humidity of midsummer.
Spring has a particular appeal. By November, jacaranda trees are flowering across the city, bringing flashes of purple to streets, parks and plazas. Autumn is equally enjoyable, with warm days gradually giving way to cooler evenings.
December to February can be hot and humid, and January in particular has a quieter feel as many locals leave the city for their summer holidays. Winter is cooler, but rarely severe, so Buenos Aires remains easy to include in a wider Argentina trip throughout the year.
