There is no particular Monsoon season for Kalpakkam as rains are unpredictable here, although there is heavy rainfall in the months of October and November, usually turning into a storm.

A study by the Madras Atomic Power Station(MAPS) revealed that the pollution in Kalpakkam is very low, which when compared to the neighbouring city Chennai is 50 times less.
