Overnight rain in Delhi brings relief from hazardous air quality

Overnight rain led to a rapid improvement in Delhi’s air quality on Friday morning and cleared the haze that had been lingering for over 10 days.

Delhi’s AQI stood at 376 at 9 am, rapidly improving from 408 at 7 am on Friday and 460 at 11 pm on Thursday. The air quality is expected to improve further due to wind speed favourable for the dispersion of pollutants.

The air quality index (AQI) at any given time is the average of readings taken in the last 24 hours.
