🌫️ Delhi Chokes: AQI Remains ‘Very Poor’ With Severe Spikes As Cold Wave Traps Toxic Smog

Experts Warn of Worsening Crisis: Local Emissions and Stagnant Winds Keep Pollution Levels Hazardously High

The national capital territory of Delhi continues to battle a persistent public health emergency as the Air Quality Index (AQI) remains stubbornly high. As of November 28, 2025, the overall Delhi Air Quality Very Bad reading hovers in the ‘Very Poor’ category (301-400), with many localized hotspots like Anand Vihar, Jahangirpuri, and Bawana recording ‘Severe’ levels (401-500) due to concentrated pollutants. The toxic air has now lingered for weeks, creating a blanket of smog that refuses to dissipate.

Meteorological and Local Factors Compound the Crisis

The primary culprits behind the consistently high pollution are a combination of adverse weather patterns and pervasive local emissions.

1. Stagnant Air: The onset of the cold wave has brought with it low temperatures and light, stagnant winds. These poor ventilation conditions effectively trap pollutants close to the ground, preventing dispersion and leading to continuous accumulation of toxic particulate matter.
2. Local Sources: While the contribution of external stubble burning has seen recent fluctuations, experts point to local sources as the main driver of the current spike. Uncontrolled vehicular emissions, massive construction dust, industrial fumes, and waste burning remain the core issues keeping the Delhi Air Quality Very Bad.

Government Action and Public Health Warning

In an attempt to manage the hazardous situation, the Commission for Air Quality Management (CAQM) has kept mandatory restrictions in place. While Stage III of the Graded Response Action Plan (GRAP), which involves bans on non-essential construction and certain vehicle categories, was recently revoked due to a marginal dip in the overall AQI, Stages I and II remain active. Authorities have intensified measures to ensure construction sites adhere to dust control norms and to curb the use of polluting sources like diesel generators.

However, the persistent readings confirm the Delhi Air Quality Very Bad status poses a severe threat to public health. Health experts strongly advise:

• Minimizing all outdoor physical activity.
• Wearing N-95 or equivalent masks when stepping outside.
• Seeking immediate medical help for any respiratory distress.

The long-term solution requires sustained, year-round efforts to tackle fundamental sources of pollution rather than relying solely on emergency, seasonal measures.
