Delhi's Air Quality Fluctuates Between Poor and Very Poor
Delhi's air quality has been changing between 'poor' and 'very poor' categories.
On Sunday, it improved to 279, which is 'poor', but on Monday, it went back up to 299.
Some areas like Nehru Nagar had very high pollution levels, while places like NSIT Dwarka had better air quality.
This year, Delhi has had its best air quality in eight years, with fewer very bad days.
The government and environmentalists have different ideas about why the air is getting better.
It's also getting colder, with temperatures dropping and a cold wave expected.
There might be fog in the mornings, which can make it harder to see.
Delhi's AQI fluctuated between 'poor' (279 on Sunday) and 'very poor' (299 on Monday).
Nehru Nagar recorded the highest AQI at 354, while NSIT Dwarka had the lowest at 195.
Delhi's average AQI for January–November 2025 was 187, the lowest in eight years.
The city experienced only three days in the 'severe' AQI category this year.
Vehicular emissions contributed 18.6% to Delhi's pollution on Sunday and 20% on Monday.
