Delhi-NCR air quality deteriorates as winter approaches
IN · Published Oct 23, 2026
• Air quality in Delhi-NCR has worsened, with the Air Quality Index (AQI) remaining in the 'poor' category as temperatures drop ahead of winter.
• On October 21, Delhi recorded its first 'poor' air quality day of the season, with an AQI of 245, the highest in 100 days.

Impact & Risks

The poor air quality poses significant health risks, particularly for vulnerable groups such as children, the elderly, and those with pre-existing respiratory conditions. Prolonged exposure to high pollution levels can lead to respiratory and cardiovascular issues. The situation is exacerbated by the onset of winter, which brings lower temperatures and reduced wind speeds, trapping pollutants closer to the ground. The combination of local emissions, stubble burning, and festive activities has further worsened the air quality, making it a public health concern.
