🇿🇦 Johannesburg vs 🇺🇸 Chicago

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.

Humid continental — cold harsh winters, hot humid summers, severe storms

Chicago lives up to its Windy City nickname. Lake Michigan creates its own microclimate — cooler summers and heavier lake-effect snow in winter. Summers are warm but brief; winters are among the harshest of any major American city.
