Winds Clear Delhi Skies: AQI Improves, But Dip Expected
26 Dec
Summary
- Delhi's AQI improved to 234 from 271 due to sustained winds.
- Forecasters predict air quality may worsen to 'Very Poor' by Dec 27.
- Wind speeds and clear skies aided pollutant dispersal over NCR.
Delhi experienced a welcome improvement in air quality on December 26, 2025, with the Air Quality Index (AQI) falling to 234 from the previous day's 271. This positive shift was primarily driven by strong, sustained winds blowing at speeds up to 22 kmph, which effectively dispersed accumulated fine particulate matter near ground level.
The favorable atmospheric conditions, including clear skies and a day temperature of 22 degrees Celsius, contributed to better ventilation. This allowed for the dispersal of pollutants originating from various sources, including vehicle emissions and industrial activity, in Delhi and neighboring NCR districts. Despite this temporary respite, forecasts indicate a potential decline.
By December 27, 2025, forecasters predict a return to 'Very Poor' air quality as wind speeds are expected to diminish and foggy conditions are likely to prevail. The ventilation index is projected to remain below the favorable threshold, trapping pollutants close to the surface for an extended period.
