Moreover, as per the weather forecasting and research body, the AQI of Mumbai today is poor because of low dispersion and low-temperature variation. In addition, local emissions will lead to poor AQI for Mumbai for the next two days.
On the first day of 2021, the city had clocked the highest pollution levels in four years. While lower than December 31, Mumbai's overall AQI of 307 was still in the very poor category. Besides, it was also observed that the air quality in and around Mumbai deteriorated from ‘poor’ to ‘very poor’ for the first time in 2020 on New Year's Eve, December 31. Experts attributed the very poor quality of air to the inflow of air from the land (continental air) instead of that from the sea.
