Being the 8th biggest country in the world and having a variety of terrains, means that the weather in Argentina is just as diverse as the country. Some of the regions — like Salta and Iguazu Falls — are warm all year round, while Tierra del Fuego is really cold in July.
Generally speaking, the predominant climate is temperate with extremes ranging from subtropical (in the north) to subpolar (in the south). The north has very hot and humid summer and dry winters, while the center has hot summers with the occasional thunderstorms. The south has warm summer and very cold winters with heavy snowfall.
Being located in the southern atmosphere, the seasons are reserved from those in the northern hemisphere.
- Autumn: February – March
- Winter: May – July
- Spring: August – October
- Summer: November – January
So the coldest period will always be mid-year while the hottest time is around New Years.
But some parts of the country have their own specific climate. If you plan to visit Patagonia make sure to arrive there during summer (November to January). The region is so close to the artic that during winter many places are closed because of the bitter cold.
If you want to visit Iguazu Falls — or other northern cities — plan your trip for winter when the temperatures are nice enough. Summers spell scorching hot weather.
As for the capital, you’d find the weather here resembling the one on the Eastern Coast of the US. No snow during winter, but the temperatures can go down below freezing. Nice springs and autumns while the summers can get a bit too hot.

Best time to visit
The best time to visit the country depends on where you plan to spend your vacation. The northern part is at its best —for the visitors —during winter (May — July) although torrential rains are quite common. The capital is at its best during spring (August — October). If you want to visit Patagonia, make sure to plan your trip for the summer (November — January).
January is holiday time all over the country and is advisable to avoid planning your vacation then. It’s crowded and the prices are at their highest.
