Hillbrow Weather in September
Hillbrow, Johannesburg, South Africa
About Hillbrow in September
Hillbrow's extreme residential density — among the highest in Africa — and wall-to-wall high-rise apartment towers create a severe urban heat island with minimal nighttime cooling. The near-total absence of green space and permeable surfaces amplifies summer heat stress and concentrates stormwater runoff during the Highveld's intense afternoon thunderstorms.
