The Commission for Air Quality Management  (CAQM) has stated that, since 2018, the national capital Delhi witnessed its best Air Quality Index (AQI) for the month of May this year at 170. The average AQI for the month of May was 217 in 2018, 221 in 2019, 212 in 2022, 171 in 2023 and 223 in 2024 respectively. 

The national capital witnesses bad AQI throughout the year, which peaks during the winter season when the stubble smoke from the farms of Punjab and Haryana reach Delhi and gets trapped with the vehicular pollutants and construction dust. Low wind speed during the winter season traps all the pollutants, engulfing Delhi with smog - a toxic mix of smoke and fog.

Additionally, the period between January to May in 2025 did not experience a single day with average AQI more than 400. There were 7 such days in 2019, with other years reporting lesser days than that.
