Air quality in Mumbai has taken a dip and it is expected to remain in the poor category in the coming days too.


It was a hazy Christmas for people of Mumbai as well as the air quality in the city again took a beating. Mumbaikars woke up to a smog-filled sky and the overall air quality on the day continued to be poor. According to the System of Air Quality Weather Forecasting and Research (Safar), the overall air quality of the city was recorded at 257, which calls under the “poor category

In the morning, recorded AQI of 240 and it continued to get worse as the day progressed. This was the worst since February. On February 10, Mumbai had recorded an AQI of 264. It is being said that the moisture-laden weather is said to be the reason for the bad air quality in the island city.  Safar is currently monitoring 10 locations in Mumbai and out of these 10, AQI of over 310 was recorded in places like Andheri, BKC, Worli, Mazgaon and Malad. BKC was the most polluted place with an AQI of 318, while Bhandup was cleanest with AQI of 175.

It is said that the air quality will continue to remain in the “poor” category in the coming two days.
