🇦🇷 Buenos Aires vs 🇿🇦 Johannesburg

Humid subtropical — hot humid summers, mild winters, year-round rainfall

Buenos Aires has a humid subtropical climate — hot and sticky summers, mild winters, and moderate rainfall year-round. The Pampas winds can create dramatic temperature swings. The city is in the Southern Hemisphere, so seasons are opposite to North America/Europe.

Johannesburg sits on the Highveld plateau at approximately 1,750m above sea level, giving it a subtropical highland climate with warm, thunderstorm-prone summers and dry, crisp winters with frequent frost. The city straddles the continental divide between the Limpopo and Vaal river systems, creating subtle drainage and elevation differences that influence local weather patterns. The world's largest urban forest — over 10 million planted trees — significantly modifies temperatures across the city, while mine dumps, ridges, and vast disparities in building density create pronounced microclimate variation between neighborhoods.
