Delhi AQI at 308 on Nov 11: Relief likely as winds pick up
Synopsis
Key Takeaways
Delhi's air quality lingered in the 'very poor' category on Wednesday, 11 November, with the overall Air Quality Index (AQI) recorded at 308 at 8:40 am. Some relief is expected over the coming days, as forecasters indicate wind speeds are likely to increase — a natural dispersant for the thick pollution blanket that has settled over the capital.
Station-wise Breakdown
Of the 59 air quality monitoring stations that reported data on Wednesday, 29 registered 'very poor' readings, while the remaining stations fell in the 'poor' category. Notably, none of the monitoring stations crossed into the 'severe' range, a marginal but meaningful distinction for public health advisories.
Among the worst-affected locations were Chhawla (398), Chandni Chowk (383), ITO (369), Pusa (361), NSIT Dwarka (352), NSUT Jaffarpur (351), NIH Narela (356), Punjabi Bagh (343), Talkatora Garden (333), Jahangirpuri (324), Wazirpur (323), Sirifort (321), Burari (319), and Badarpur (312). Comparatively cleaner readings were recorded at Karala (220), Ghoga (263), and Nangloi (274).
CPCB Scale and Platform Discrepancy Clarification
According to the Central Pollution Control Board (CPCB), AQI is classified as follows: 0–50 is 'good', 51–100 is 'satisfactory', 101–200 is 'moderate', 201–300 is 'poor', 301–400 is 'very poor', and 401–500 is 'severe'.
On Tuesday, the CPCB addressed growing public concern over data inconsistencies, clarifying that differences between AQI readings shown on private applications and its own official platform arise from variations in pollutant concentration measurements and calculation methodologies — and are not, as some reports had suggested, a result of under-reporting. The watchdog responded via a post on X in reaction to media scrutiny of AQI reporting during and after Diwali, which included questions about readings capped at 500, missing data from certain monitoring stations, and cross-platform discrepancies.
Post-Diwali Pollution Context
The current pollution episode follows Diwali celebrations on 8 November, after which India featured prominently in global pollution rankings. According to data published by AQI.in on 9 November, 93 Indian cities were among the world's 100 most polluted locations — a stark reminder of the annual post-festival air quality crisis that the capital faces with near-clockwork regularity. This is not an isolated spike; Delhi has recorded 'very poor' or 'severe' air quality in November for several consecutive years, underscoring the structural nature of the problem.
Weather Forecast: Fog and Mild Temperatures Ahead
The India Meteorological Department (IMD) has forecast fog or mist during early morning hours in Delhi from 11 to 16 November. Maximum temperatures are expected to range between 28°C and 29°C, while minimum temperatures are likely to stay between 14°C and 16°C. On 11 and 12 November, the maximum is forecast at 28°C with minimums between 15°C and 16°C; from 13 to 15 November, the maximum may edge up to 29°C.
As wind speeds strengthen in the days ahead, air quality is expected to improve gradually — though residents with respiratory conditions are advised to continue precautionary measures until readings fall below the 'poor' threshold.
