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 colored vines, stark against the backdrop of the Andes.

Month-by-month guide to traveling in Argentina

Bariloche, Argentina

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.

Melissa at Iguazu Falls, Argentina

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.
