Whilst December to March are the months in which Patagonia in the south of Argentina is most easily accessible, the whole country can be visited year round. The weather in Buenos Aires is generally hot over these months but a visit in the cooler, crisp months of July and August can be delightful. The Lake District comes alive with wildflowers over spring (September to November), whilst autumn in the wine valleys surrounding Mendoza features gold and copper coloured vines, stark against the backdrop of the Andes.

Visiting Argentina in January - February
The height of Argentina's summer, January and February are popular months to visit Patagonia; particularly El Calafate and Bariloche. Accommodation here gets busy quickly at this time of year. In January it can be quite wet in the northwest of the country and extremely hot in the northeastern wetlands area.
Visiting Argentina in March
A lovely month to travel to Argentina. Summer is drawing to a close across the country but Patagonia is still accessible and trekking is easy to organise.
Events & Festivals
- Mendoza Wine Festival (March): This festival celebrates the harvest of the area's grapes. Shows featuring dancers in traditional costume portraying the work involved in the harvest take place across the province.
Visiting Argentina in April
Autumn is a beautiful time of year to visit Patagonia and Mendoza's winelands. The crowds have thinned and the colours of the changing trees provide magnificent photo opportunities.
Visiting Argentina in May
A good time to visit Argentina's wetlands, Esteros de Ibera, May and June are cooler months here and offer good wildlife spotting opportunities.
Visiting Argentina in July - August
July and August are good months to visit Buenos Aires. Evenings are cooler and the mornings are fresh, ideal for exploring on foot. Ski season begins in earnest in July.
Events & Festivals
- Buenos Aires Tango Festival (August): This annual festival sees two weeks of free events, featuring performances by the world's best tango dancers, art exhibitions and opportunities for visitors to get involved. Read more »
Visiting Argentina in September
September and October are good months to visit the Peninsula Valdes. It's a great time for wildlife lovers, and you can expect sightings of whales, seals, penguins and lots of sea birds.
Visiting Argentina in October
Spring in the Lake District around Bariloche is a lovely time to visit and enjoy the carpets of wild flowers. There are great opportunities for a variety of outdoor activities, although rainfall here can be slightly higher than in the rest of the year. Southern Patagonia is also reawakening.
Visiting Argentina in November
The end of spring and start of summer. A visit to Argentina in November generally means avoiding the crowds that build up for December. It's one of the greener months to visit the often arid landscape of Salta and the northeast.
Visiting Argentina in December
The middle of Argentina's summer can be a busy time to visit, but also offers the best chance of warm, clear weather in Patagonia. The rains that have fallen at the Iguazu Falls means the volume of water roaring over the falls is high and the scenery here is dramatic.

Melissa, Latin America Specialist
For me, October is an excellent time to visit Argentina. The heat of the summer in Buenos Aires hasn't arrived, but Patagonia's spring flowers are blooming and the whales and penguins are easy to spot from the Peninsula Valdes.
