Delhi National Capital Region experiences one of the most severe pollution crises in mid-December 2025, with hazardous air quality engulfing the entire region on Monday, December 15. The Air Quality Index across Delhi has soared to catastrophic levels, with readings ranging from 535 to 696 in the hazardous category, representing an air disaster where PM2.5 particles reach 424–455 µg/m³ and PM10 levels exceed 599 µg/m³, all far surpassing safe standards. Dense fog blankets the capital and surrounding areas, including Noida, Ghaziabad, Faridabad, and Gurugram, reducing visibility to dangerous levels that disrupt vehicular traffic and force flight operations into severe alert mode.
Simultaneously, temperatures fluctuate dramatically between bitterly cold early mornings at 8–11°C and relatively pleasant afternoons reaching 23–26°C, creating a substantial day-night differential that characterizes Delhi winter conditions. The combination of hazardous air quality, dense fog, and cold temperatures creates a perfect storm of adverse weather and pollution conditions, forcing authorities to implement the strictest emission control measures and health alerts across the National Capital Region.
