The air quality continued its relentless deterioration in Delhi on Wednesday, with the air quality index (AQI) climbing to 377, deep in the “very poor” category, as a choking haze engulfed the Capital days before Diwali fireworks are expected to add to the pollution burden.
To make matters worse, forecasts by the Air Quality Early Warning System indicate the situation is expected to worsen further. It states that Delhi could enter the “severe” category – the worst on the AQI scale – on November 6 and 7, just as firecracker bursting begins. The air is then likely to remain severe for nearly a week.

CAQM steps up action as Punjab farm fires increase
The deterioration comes as authorities are also grappling with rising farm fires in Punjab. The Commission for Air Quality Management (CAQM) on Wednesday reviewed the increase in paddy stubble burning incidents and directed authorities to intensify monitoring and enforcement.
CAQM chairperson Rajesh Verma held a video conference with senior officials, deputy commissioners and senior superintendents of police from 12 districts. Nodal officers will be held accountable for lapses, while community leaders will be roped in to prevent farm fires. The commission also directed thermal power plants to ensure at least 5% biomass co-firing, warning of statutory action for non-compliance. A high-level team is assessing the situation in Bathinda.
Meanwhile, Delhi recorded a maximum temperature of 29.8°C on Wednesday, 0.7 degrees below the seasonal normal, while the minimum settled at 16.1°C at Safdarjung, according to India Meteorological Department data. No rainfall was recorded.
