Delhi's Air Quality Improves Temporarily, but Forecast Remains Grim
25 Oct
Summary
- Air quality in Delhi improved from "very poor" to "poor" on October 25, 2025
- Increased wind speed led to the improvement, but it is expected to be short-lived
- A western disturbance is expected to impact the region from October 27, potentially bringing light rain
As of October 25, 2025, Delhi's air quality has seen a temporary improvement, with the 24-hour average Air Quality Index (AQI) dropping from "very poor" to "poor" levels. This change was driven by increased wind speed, which helped disperse the pollutants.
Throughout the day, the real-time air quality continued to improve, with the AQI reading 290 at 9 am, 286 at 11 am, and 272 at 6 pm. However, this improvement is likely to be short-lived, as forecasts suggest the air quality may return to "very poor" levels in the coming days.
According to the Air Quality Early Warning System (AQEWS), the AQI is expected to be in the "poor" category on October 26 and then deteriorate to the "very poor" category from October 27 to October 28. The outlook for the subsequent six days also indicates the air quality is likely to oscillate between "very poor" and "poor" levels.
The potential respite may come in the form of a western disturbance expected to impact the region from October 27 to October 29. This weather system could bring light rain or drizzle, which may further improve the air quality. However, if the rain does not materialize, the western disturbance could also bring dusty winds, potentially leading to a spike in pollution levels.
As Delhi residents brace for the fluctuating air quality, the city's authorities will need to remain vigilant and implement appropriate measures to address the persistent pollution challenge.
