The drastic decrease in rainfall is a significant departure from the heavy downpour the city experienced in July, when the Colaba observatory recorded 1176 mm of rainfall.

The dramatic turn in the monsoon season has significant implications for the city's water supply and agricultural production. The BMC and the state government will need to take measures to mitigate the effects of the drought-like situation.
