Delhi's Air Quality Improves, But Challenges Remain Ahead of Diwali
24 Oct
Summary
- Delhi's air quality improved from "very poor" to "poor" on October 24, 2025
- Minimum temperature dropped to 17°C, compared to 18.1°C a day earlier
- Air quality expected to oscillate between "poor" and "very poor" in the coming days
As of October 24, 2025, Delhi's air quality has improved from the "very poor" to the "poor" category, with an air quality index (AQI) of 290 recorded at 9 am. This improvement comes after four consecutive days of "very poor" air quality in the city.
The change is attributed to a slight increase in wind speed, even as the minimum temperature dropped to 17°C, compared to 18.1°C the previous day. The maximum temperature on October 23 reached 32.2°C.
Despite the temporary relief, the outlook for Delhi's air quality remains uncertain. The Centre's Early Warning System for Delhi predicts that the AQI is likely to remain in the "very poor" range until at least October 27. Over the subsequent six days, it could oscillate between "poor" and "very poor" as variable easterly winds continue to keep stubble burning emissions away.

The city is bracing for potential air quality challenges in the coming days, as it approaches the Diwali festival. On October 23, Delhi recorded its first "very poor" air day of the season, but the winds of up to 10 km per hour the next day helped disperse the emissions, preventing the AQI from reaching the "severe" category.
