New Delhi: Dense smog continued to shroud Delhi on Thursday morning, with air quality worsening again as the Air Quality Index stood at 356, according to data from the Central Pollution Control Board.

Of the 39 air quality monitoring stations across the capital, four recorded ‘severe’ air quality levels, while several others remained close to the same category, highlighting persistently hazardous conditions.

Reduced visibility was reported across several parts of Delhi and the NCR as thick smog enveloped roads, residential areas and public spaces, disrupting daily movement and raising health concerns among residents.

Data from the Commission for Air Quality Management’s SAMEER app showed the AQI at 358 at 7 am, reversing the marginal improvement recorded a day earlier when air quality had slightly improved due to stronger winds.

The India Meteorological Department said foggy conditions were expected during the early hours of the day, but added that surface winds were likely to limit prolonged fog formation and help improve visibility as the day progressed.

According to the weather office, north-westerly surface winds of up to 10 kmph were expected in the morning, increasing to around 15 kmph in the afternoon before easing in the evening and night, aiding dispersion of fog during daylight hours.

Meanwhile, the Delhi government’s pollution-control measures came into effect on Thursday, including enforcement of the ‘No PUC, No Fuel’ rule. Entry of non-BS-VI vehicles registered outside Delhi has also been barred, while trucks carrying construction material remain banned. Construction activity continues to be prohibited under GRAP norms, with authorities warning of strict action against violators.
