Delhi's Air Quality Deteriorates Post-Diwali, Reaches 5-Year High
IN · Published Nov 9, 2026
• Delhi experienced its most polluted Diwali in five years, with the Air Quality Index (AQI) reaching an average of 376 on November 8,
• The following morning, the AQI remained high at 371, with dense smog and fog blanketing the city. Visibility dropped significantly, with Safdarjung reporting 50 metres and Palam 400 metres at 6:30 am. The India Meteorological Department (IMD) confirmed the presence of smog combined with fog, caused by dry weather and calm winds. The Swiss air quality monitoring platform IQAir classified Delhi's air quality as 'very unhealthy,' with PM2.5 levels at 170 µg/m³, 34 times the World Health Organization's annual guideline value.

Impact & Risks

The severe air pollution poses significant health risks, particularly for vulnerable groups such as children, the elderly, and those with respiratory or cardiovascular conditions. Several areas, including Bawana, Burari, and Punjabi Bagh, recorded severe air quality levels. The dense smog also reduced visibility, affecting transportation and daily activities. The combination of firecracker emissions, vehicular pollution, and stubble burning in neighbouring states has exacerbated the situation.
