Plan your trip to Argentina


Bear in mind that seasons are reversed in the southern hemisphere; summer is from December to February, and winter from June to August.
Travel to the northwestern region isn’t recommended from December through the end of February, as the Andean summers are quite rainy.
Patagonia, in the south, is best explored from October to March. Nonetheless, it can be cold all year round, sometimes with high winds.
Buenos Aires, the capital and its surrounding region, can be humid. In January the mercury can rise above 100°, and in July it can drop into the 40s.
The northeast, and especially Iguazu Falls, has a subtropical climate, and is hot and humid all year round.

Spanish has been the official language of Argentina since the 16th century and Spanish colonization, as in most South American countries. Nonetheless, many indigenous languages have endured from pre-colonial times, such as Quechua in the northern Andes and Guarani in the northeast.

Given the relative instability of the Argentine economy, we recommend that you verify the exchange rate before leaving for your trip.
