The climate of Argentina ranges from the great heat and extensive rains of the subtropical Chaco in the north, through to the pleasant climate of the central Pampas and the sub-Antarctic cold of the Patagonian Sea in the south. The main central area is temperate, but can be hot and humid during summer (December to February) and cool in winter.

Lightweight clothing in the north. Warm clothes are necessary in the south, in the mountains and during winter months in the central area. It is sensible to carry waterproofs in all areas.
