Mumbai's Air Quality Declines Sharply in October Amid Slower Coastal Winds
Mumbai experienced a significant rise in air pollution during October, with the average daily air quality index more than doubling from 45.4 in September to 102 by October 27. This marks one of the sharpest deteriorations in recent years, driven by slowed coastal winds due to a strong El Niño effect, which reduced the dispersion of pollutants. Increased local emissions from traffic, construction, and industry also contributed. Mumbai briefly became India's most polluted city, with PM2.5 concentrations tripling, reaching levels classified as unhealthy.
