Argentina weather overview

This vast country, which is almost as large as India, has a varied topography and climate. Northernmost Argentina is tropical, which means high temperatures and high humidity in the summer months (November to March) and rain throughout the year.

Central Argentina, which includes Buenos Aires and the Pampas to the east, has a healthy and pleasant climate, which is warm but fairly rainy in the summer and mild in the winter.

Further west and to the south, the climate is sunny and drier and drought can occasionally be a problem. Western Argentina, including the northern Andes, is a dry region: even on the mountain peaks, which rise as high as 7,000 m (23,000 ft), rain and snowfall is low.

What rain there falls mainly during the summer months which are very sunny and hot. This climate makes the eastern slopes and foothills of the Andes very arid while the surrounding lowlands are desert.

Southern Argentina (also known as Patagonia) is largely dry but temperatures are cooler and the far south has chilly summers and long winters with plenty of frost and snow. However, the region's proximity to the Atlantic Ocean stops temperatures falling unbearably low.

What to pack for Argentina weather

Pack light cotton clothes for northern and western Argentina (unless going high up into the Andes) and for Central Argentina in their summer.

Take warmer wear for central districts in winter and summer visits to the south. Wrap up very warmly for the winter months in Southern Argentina. Even dry Western Argentina experiences some rain, so go prepared.
