Delhi’s air quality stayed in the ‘poor’ category on Sunday as the city registered an overall Air Quality Index (AQI) of 248, according to data from the Central Pollution Control Board (CPCB). Authorities warned that prolonged exposure to the degraded air could cause breathing discomfort for many residents, while a thin veil of smog reduced visibility across parts of the capital.
Delhi air quality key readings and health advice
Several central monitoring stations recorded readings in the ‘very poor’ range. Anand Vihar reported an AQI of 350, Rohini 361, Chandni Chowk 355, Mundka 329 and R.K. Puram 322. ITO also exceeded 300, registering an AQI of 309. By contrast, NSIT Dwarka and Indira Gandhi International (IGI) Airport were in the ‘moderate’ range with values of 177.
Medical experts advise that people with respiratory or cardiovascular conditions, older adults and young children should avoid prolonged outdoor exertion. Those who must go outside are encouraged to limit time spent near busy roads, consider wearing protective masks rated for particulate matter filtration and consult a physician if symptoms such as persistent coughing or shortness of breath develop.
Preparations for national events continue
Despite the smog, Republic Day parade rehearsals proceeded at India Gate, where a visible layer of pollution reduced sightlines. Security personnel and parade participants continued preparations as scheduled for the upcoming national celebrations, with organisers monitoring conditions to minimise health risks to participants and spectators.
Weather outlook and official response
The India Meteorological Department (IMD) reported a minimum temperature of about 9°C on Sunday morning and noted fog during the early hours. Weather conditions were expected to improve from the afternoon, with a forecast maximum between 18°C and 19°C and a minimum likely in the range of 7°C to 8°C.
The Sub-Committee on the Graded Response Action Plan (GRAP) under the Commission for Air Quality Management (CAQM) revoked Stage-III restrictions on Friday evening, citing improved conditions driven by favourable meteorology. Nevertheless, authorities urged strict adherence to Stages I and II of the GRAP schedule to prevent renewed deterioration.
The government emphasised that construction and demolition sites subject to closure orders for violations or non-compliance will not be allowed to resume operations without explicit approval from the Commission. The Sub-Committee said it will continue to monitor the situation closely and make further decisions based on forecasts from the IMD and the Indian Institute of Tropical Meteorology (IITM).
Practical steps for residents
Residents can help reduce short-term exposure by avoiding outdoor exercise during peak pollution hours, using indoor air purifiers where possible and maintaining good ventilation when outdoor air quality improves. Commuters should consider public transport options that reduce overall vehicle emissions when feasible.
With festival and national events approaching, authorities and citizens alike face the twin tasks of protecting public health and ensuring essential activities proceed safely. Continued monitoring and compliance with GRAP measures will determine whether air quality improves in the coming days.
Key Takeaways:
- Delhi air quality remains in the ‘poor’ category with overall AQI at 248, causing breathing discomfort for many residents.
- Several monitoring stations recorded ‘very poor’ readings, including Anand Vihar and Rohini above 350.
- Republic Day rehearsals continued despite reduced visibility; IMD forecasts improving weather from the afternoon.
