Mumbai's overall AQI is at 194 (moderate) with several areas reporting poor or very poor air quality. Calm winds are contributing to the decline in air quality. The Bombay High Court has taken note of the issue and the BMC has implemented measures to mitigate air pollution.

Mumbai: Mumbai’s overall Air Quality Index (AQI) dipped to 194 (moderate) at 6pm on Friday, as per the website of the Central Pollution Control Board (CPCB).

Sunil Kamble, director of the Indian Meteorological Department, Mumbai said that calm winds were pulling the air quality down. “Whenever the wind is calm, the city sees a rise in AQI. This is likely just temporary – with winds getting better, the AQI will also get better. Usually, the winds change every 6-7 hours,” he said.

On November 1, 2023, the Bombay high court had taken note of newspaper reports highlighting poor air quality in the city. The court had taken up suo-motu proceedings saying the news articles presented “an alarming scenario and one which needs to be urgently addressed and tackled in the welfare and interest of all the residents of Mumbai and its surrounding areas, young and old alike”.

On October 25, 2023, the BMC had come up with a stringent 27-point guideline for air pollution mitigation, which included covering construction sites with green cloth, using sprinklers and anti-smog guns, forming ward level squads and empowering ward officers to issue stop-work notices and seal sites in case of violations.
