Delhi Air Quality Index deteriorates to 'Very Poor' category with AQI at 316

Index | Dated: 03 Nov 2025

Delhi's Air Quality Index (AQI) was recorded at 316, officially placing it in the 'Very Poor' category as reported by the Central Pollution Control Board (CPCB). This marks a significant spike in pollution levels due to a combination of factors. The deterioration is primarily linked to lower wind speeds which hinder the dispersion of pollutants, and the ongoing issue of stubble-burning in neighboring states, aggravated by vehicle and industrial emissions.

🎯 Key Highlights:

  • The overall AQI recorded by CPCB was 316.
  • An AQI between 301 and 400 is considered 'Very Poor'.
  • The spike in pollution is linked to low wind speeds and stubble-burning.

💡 Other Important Facts:

  • The deterioration is linked to adverse meteorological conditions.
  • Urban emissions from traffic are also a constant pollutant source.
  • Health experts advised vulnerable groups to limit outdoor exposure.
