Argentina (Buenos Aires) – What you should know
Buenos Aires lies at latitude 34°S — climatically similar to Cape Town but with more pronounced temperature extremes. Summer (December to February) is hot and humid with highs typically up to 29°C (84°F), higher on heat days. Winter (June to August) brings cool lows of typically 7–8°C (45–46°F) without much rain. There is no true rainy season — precipitation is distributed fairly evenly throughout the year.
The ideal travel time for Buenos Aires is spring (September to November) and autumn (March to May): pleasant temperatures, a lively cultural scene and parks full of blossom or colourful foliage. During these seasons, most outdoor city life takes place — from markets in the San Telmo district to tango events in the milongas.
Those who want to visit Patagonia and Tierra del Fuego should travel from November to March (southern summer): at this time the national parks are accessible, the glaciers of the Perito Moreno Glacier well visible and conditions for trekking at their best. Even in summer it can be stormy and cold in Patagonia — layered clothing is a must.
