The AQI levels in the areas surrounding the national capital also remained in the 'poor' and ‘very poor’ category, though still better than Delhi. In Haryana's Gurugram, the AQI was recorded at 281, while in Faridabad, it stood at 250, according to the data issued by the Central Pollution Control Board (CPCB) on Sunday night. As per the data, the AQI in Uttar Pradesh's Noida stood at 313, while in Ghaziabad, it was 290.

The AQI, when under the ‘poor’ category, can cause breathing discomfort to people on prolonged exposure, whereas, when under the ‘very poor’ category, it can cause respiratory illness on prolonged exposure, according to CPCB.

Despite the temporary relief provided by the winds, Delhi saw a spike in pollution levels following Diwali, with a noticeable jump recorded on Sunday.

During the winter months, Delhi and surrounding areas experience severe pollution, driven by a combination of factors, such as low wind speeds, dropping temperatures, high moisture levels and the presence of pollution particles that act as surfaces for condensation.
