About Mong Kok in September
Mong Kok holds one of the highest population densities on Earth, and its tightly packed residential towers, narrow streets, and almost zero vegetation create an extreme urban heat island that rarely cools below 29°C on summer nights. Air stagnation between buildings traps vehicle exhaust and cooking fumes, making street-level air quality among the worst in the territory.
