Delhi’s air quality improves to ‘moderate’ after 50 days, ‘poor’ forecast for Friday
Delhi's air quality is expected to stay ‘moderate’ till Thursday, but may worsen to ‘poor’ on Friday, according to the Air Quality Early Warning System.
Delhi experienced cleaner air on Wednesday after 50 days, with the air quality categorised as ‘moderate,’ offering much-needed relief from the pollution.
The 24-hour average air quality index (AQI) of the city was recorded at 178 by 4 pm, a significant improvement from 268 on Tuesday.
Previously, the AQI had been in the ‘moderate’ category, with a reading of 198 on October 15. However, it worsened to the ‘poor’ category the next day, according to Central Pollution Control Board (CPCB) data.
An official from the India Meteorological Department (IMD) attributed the improved air quality to strong surface winds, which were expected to continue through December 7.
These winds will likely be followed by a new western disturbance, leading to moderate fog from December 8.
Out of the 38 air quality monitoring stations in the city, only Sri Aurobindo Marg recored ‘very poor’ air quality, while eight others showed ‘poor’ quality. The rest were in the ‘moderate’ category, according to CPCB data.

The Air Quality Early Warning System for Delhi has forecasted that the air quality is likely to remain in the moderate category from Thursday, with a prediction of deterioration to the poor category on Friday and Saturday.
With clean air, the daytime temperature was recorded at 28 degrees Celsius, three notches above the normal, according to the India Meteorological Department (IMD).
