Delhi’s Air Quality: Current Status and Future Forecast
As of December 25, 2025, Delhi’s air quality has shown slight improvement, but forecasts predict a deterioration in the coming days. The capital city recorded an Air Quality Index (AQI) of 234, which falls into the ‘poor’ category, a significant improvement from the severe levels witnessed earlier in the week.
Current Air Quality Status
According to the Central Pollution Control Board (CPCB), the AQI in Delhi was measured at 234 at 4 PM on December 25. This marks a notable decrease from the previous day’s AQI of 271 and an even more significant drop from the severe AQI of 412 recorded on December 23. The improvement in air quality has been attributed to various factors, including changes in weather conditions and reduced pollution levels from certain sources.
Monitoring Stations Data
Out of the 40 functional air quality monitoring stations in Delhi:
- 10 stations reported moderate AQI levels below 200.
- 27 stations remained in the poor category.
- 2 stations, Jahangirpuri and Bawana, recorded very poor air quality with AQI readings above 300.
Notable locations with moderate AQI levels included:
- Lodhi Road
- IIT Delhi
- Indira Gandhi International Airport
- Aya Nagar
Sources of Pollution
Transport emissions have been identified as the largest contributor to Delhi’s air pollution, accounting for 18.5% of the total pollution load. Other significant contributors include:
- Industries in Delhi and adjoining areas: 9.5%
- Construction activities: 2.5%
- Waste burning: 1.6%
In addition, data from the Decision Support System (DSS) for Air Quality Management indicated that pollution from neighboring districts in the National Capital Region (NCR) also plays a significant role. Jhajjar in Haryana contributed the highest share at 17.6%, followed by Rohtak at 5.9% and Sonipat at 3.1%.
Weather Conditions
Weather conditions have also influenced air quality. On December 24, Delhi recorded a maximum temperature of 22.6 degrees Celsius, which is 1.9 degrees above normal, while the minimum temperature was 6.5 degrees Celsius, slightly below normal. The relative humidity levels were measured at 63% in the morning and 84% in the evening.
The India Meteorological Department (IMD) has forecasted a minimum temperature of 8 degrees Celsius for Christmas Day, along with the possibility of moderate fog.
Future Forecast
Despite the recent improvement, forecasts indicate that Delhi’s air quality is likely to deteriorate to the very poor category in the upcoming days. The predominant surface wind direction has been from the northwest, with wind speeds reaching up to 10 km/h during the afternoon hours on December 25. This change in wind patterns may exacerbate pollution levels as emissions from surrounding areas continue to impact the capital.
Conclusion
Delhi’s air quality remains a pressing concern, with recent improvements overshadowed by forecasts of deterioration. The ongoing contributions from transport emissions, industrial activities, and pollution from neighboring regions highlight the need for comprehensive air quality management strategies. As the city prepares for potentially worse air quality, it is crucial for residents to stay informed and take necessary precautions to protect their health.
