🇭🇰 Hong Kong vs 🇿🇦 Johannesburg

Humid subtropical — hot wet summers, mild dry winters, typhoon season

Hong Kong has a dramatic climate shaped by the South China Sea and its mountainous terrain. Winters are mild and dry; summers are brutal with typhoons. The autumn window (October–December) is widely considered the best time to visit.

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.
