Weather

Due to the country's geography and location, Argentina & Patagonia offers a wide variety of climates. The Argentine mainland is mostly temperate, with seasons reversed from those in the northern hemisphere. The northern areas of Salta and around Iguazú are tropical, while southern Patagonia's weather is often cold and windy and always unpredictable.

Winter (from the end of June to the beginning of October) may be cold with some rain in certain areas of Argentina, while the Northwest enjoys sunny days and warm temperatures.

Summer (from December to March) is hot and sometimes humid in Buenos Aires; warm and dry in the Northwest with intermittent summer rains; and cold but sunny and sometimes windy in Patagonia.
