Mumbai's air quality dips to unhealthy levels on Diwali

India Oct 20, 2025

Mumbai's air quality took a hit on the day of Diwali, with the city's AQI dropping to 187 on Monday morning.
Some areas like Bandra Kurla Complex and Colaba saw even higher levels, thanks to a mix of firecracker smoke and dust from construction.

La Niña's impact

With La Nina slowing down winds, all that pollution just hangs around longer.
This means more days of breathing unhealthy air—especially tough for anyone with asthma or other respiratory issues.
City officials are asking construction sites to spray water to keep dust down, but real relief might only come with a change in weather.
