It has also issued yellow alert for ‘dense’ to ‘very dense’ fog. The maximum and minimum temperatures over Delhi are currently in the range of 15 to 19°C and 8 to 9°C respectively. The deteriorating air quality level in the national capital can be attributed to foggy conditions and absence of strong winds. Fog worsens air quality by trapping pollutants close to the ground and preventing it from spreading. Notably, following the improvement in AQI, the CAQM had withdrawn Stage-III restrictions on Sunday, which were reinstated on January 9, 2025, after the AQI breached the 350 mark.
