Delhi pollution has entered a sharper deterioration phase, with the city’s average air quality index reaching 350 on November 3 and 10 monitoring stations recording levels above 400. The deterioration is unfolding as slow winds, morning haze, forecast increases in the contribution of stubble burning and the possibility of festival-related emissions combine to expose the limits of managing air quality within the city alone.
The average AQI recorded at 4 pm was in the “very poor” category, according to the report published by Live Hindustan – NCR with inputs from the India Meteorological Department. The reading was Delhi’s worst in 287 days, after the city recorded an AQI of 378 on January 20. Jahangirpuri reported the highest level at 452, placing it in the “severe” category.
The numbers also show that the deterioration was not a single-day fluctuation. Delhi’s AQI rose from 261 on November 1 to 324 on November 2 and then to 350 on November 3. That three-day movement matters because it indicates a sustained worsening at the beginning of a period when atmospheric conditions are already restricting the dispersal of pollutants.
The immediate urban consequence is a city operating under increasingly poor air conditions across multiple monitoring locations rather than a problem confined to one neighbourhood. The report does not provide station-level readings for all 10 locations above 400, but the spread of severe readings indicates that residents in different parts of Delhi were being exposed to substantially degraded air at the same time.
The meteorological conditions described in the report help explain why emissions can accumulate. The IMD has forecast morning haze across Delhi and the National Capital Region through November 9. Wind speeds are expected to remain low during the morning and evening through the week, while north-westerly winds are expected to continue until November 6. In such conditions, pollution already present in the air is less readily dispersed, allowing concentrations to build near the ground.
This is where Delhi’s seasonal pollution problem becomes a regional governance challenge. The reported contribution from stubble burning to Delhi’s PM2.5 concentration increased from 8.583 per cent on November 2 to 15.301 per cent on November 3, according to the Decision Support System. The forecast contribution is expected to rise to 20.057 per cent on November 4 and 22.207 per cent on November 5.
These figures are important, but they also need to be read precisely. They indicate the estimated share of Delhi’s PM2.5 pollution associated with stubble burning at specific points in time; they do not mean that all of Delhi’s pollution originates outside the city. The data presented in the report instead shows a changing mix of sources, with regional agricultural fires expected to account for a larger share as weather conditions become less favourable.
The same evidence complicates a simple explanation based only on crop-residue burning. Satellite data cited in the report shows that the number of farm-fire incidents this year is lower than in several previous years. Between September 15 and November 2, 3,535 incidents were recorded across the relevant states. Punjab accounted for 1,612, followed by Rajasthan with 738, Madhya Pradesh with 614, Uttar Pradesh with 349, Uttarakhand with 176, Haryana with 44 and Delhi with two.
The longer comparison is stark. The same period recorded 51,822 farm-fire incidents in 2020. The number fell to 24,583 in 2021 and stood at 26,490 in 2022. In 2025, 4,993 incidents were recorded, while 3,535 had already been recorded between September 15 and November 2 this year. The figures suggest a substantial reduction from the levels seen in 2020, but they do not eliminate the seasonal contribution to Delhi’s air pollution.
This apparent contradiction is central to understanding the crisis. Fewer fires do not necessarily translate into clean air when the remaining fires occur during stagnant atmospheric conditions, when wind direction carries emissions towards the capital region, or when local pollution is unable to disperse. The supplied data does not establish the relative importance of each of these factors, but it does show why a reduction in fire counts alone cannot be treated as a complete measure of air-quality improvement.
The timing of agricultural fires also extends the policy challenge. The report says that stubble-burning incidents are generally recorded between September 15 and November 30. That means the pollution episode is linked to a seasonal window that lasts for weeks rather than a single festival day or isolated weather event. Delhi’s response therefore depends not only on short-term restrictions but also on coordination across states, monitoring systems and agencies responsible for agricultural practices and air-quality management.
Festival fireworks could add another source of emissions, the report notes, although it does not quantify their expected contribution. This distinction is important in public communication. Forecasts about stubble-burning contributions are presented with specific percentages, while the possible effect of fireworks is identified as an additional concern without a numerical estimate in the supplied material. The two should not be treated as equivalent evidence.
The institutional picture emerging from the report is one of overlapping responsibilities. The IMD provides weather forecasts, the Decision Support System estimates source contributions, satellite data tracks farm fires and monitoring stations record local AQI levels. Each system answers a different question: what conditions are expected, where pollution may be coming from, how many fires are visible and what residents are breathing at monitoring locations.
The strength of this arrangement is that it can connect atmospheric conditions with likely pollution sources. Its limitation is that the systems do not automatically produce a single administrative solution. A severe reading in Jahangirpuri requires a local response to exposure and emissions, while the projected rise in the stubble-burning share requires action beyond Delhi’s boundaries. Weather forecasts can identify the risk of accumulation, but they cannot by themselves reduce emissions.
The data also reveals a gap between measuring deterioration and communicating its meaning. An AQI of 350 describes a citywide average in the very poor category, while a reading of 452 at Jahangirpuri indicates severe local conditions. Residents experience the latter through neighbourhood-level exposure, not through the city average alone. A citywide number is therefore necessary for tracking the trend, but station-level variation remains essential for understanding how unevenly the crisis is distributed.
For urban residents, the immediate significance is that deteriorating air quality is occurring alongside conditions expected to remain unfavourable until at least November 9. The report does not provide health advisories, school instructions or restrictions linked to the readings, so the operational response of authorities cannot be assessed from the supplied evidence. What is established is the worsening trend, the meteorological risk and the expected increase in the contribution from crop-residue burning over the next two days.
Delhi’s latest pollution episode therefore points to a broader urban-management problem: air quality is measured inside city limits, but its sources and atmospheric behaviour cross those limits. The evidence confirms a rapid rise in AQI, severe readings at several monitoring stations and a projected increase in one regional pollution source. It also shows that lower farm-fire counts than in earlier years have not prevented a serious episode. The next developments to monitor are the AQI readings through November 9, the actual contribution of stubble burning against the forecast and the response of authorities across Delhi and the neighbouring states.
