Delhi-NCR recorded an average Air Quality Index (AQI) of 167 from January 1 to September 30 this year, the second-best for the corresponding period in six years, the Centre's Commission for Air Quality Management (CAQM) said on Saturday.

Better air quality during this period was recorded only during the pandemic-affected 2020, it said in a statement.

In 2022, 2021, 2019 and 2018, the average AQI during this period ranged from 180 to 193.

Delhi experienced its only "good" air quality day of the year, with an AQI of 45, on September 10, the final day of the G20 Summit.

Despite less rainfall in September 2023 (82.7 mm) compared to September 2022 (165 mm), the average AQI for the month this year (108) remained on par with last year (104).
