Velachery Weather in September
Velachery, Chennai, India
About Velachery in September
Velachery occupies a low-lying basin that was historically part of the Pallikaranai marshland system, making it one of Chennai's most flood-prone neighborhoods during heavy monsoon events. Rapid urbanization over former wetlands has eliminated natural water absorption, creating both severe waterlogging and an intense urban heat island where concrete has replaced marsh vegetation.
