A month after December's severe smog crisis, Delhi-NCR faces another intense cold wave with dense fog and very poor air quality on January 6, 2026. Noida schools are closed to protect students, while authorities issue health advisories amid ongoing winter hazards.
Following the escalating winter smog in mid-December 2025 that saw AQI levels exceed 450, Delhi-NCR is now gripped by a tightening cold wave, with residents facing severe cold, dense fog reducing visibility, and air quality in the very poor range, heightening health risks.
The India Meteorological Department (IMD) reports persistent cold day conditions across northern India, with fog warnings active. As a precaution, schools in Noida have shut down. Officials have released winter health advisories, emphasizing safety measures during these recurring seasonal challenges.
