Sandton Weather in September
Sandton, Johannesburg, South Africa
About Sandton in September
Sandton's dense cluster of glass-and-steel high-rises creates Johannesburg's most intense commercial urban heat island, with daytime temperatures running 2–3°C above surrounding leafy suburbs. Evening cooling is slower here than in adjacent residential areas due to heat retention in concrete plazas and parking structures.
