At 7pm, the Sector 51 station recorded the highest AQI at 363, followed by Teri Gram at 316. The Vikas Sadan and Gwal Pahari stations reported AQI levels of 328 and 302, respectively. The Sameer app, developed by the CPCB to provide real-time air quality information, carried a health advisory cautioning that the air quality remained very poor and that prolonged exposure could lead to respiratory problems. As per CPCB guidelines, an AQI between 201 and 300 is classified as "poor", a level at which prolonged exposure may cause breathing discomfort for most people. AQI levels between 301 and 400 fall under the "very poor" category, where the likelihood and severity of health impacts increase significantly. Gurugram ranked third among the most polluted cities in the National Capital Region on Saturday. Ghaziabad topped the list with an AQI of 351, followed by Noida at 348, both falling in the "very poor" category.

On Saturday, Gurugram recorded a maximum temperature of 18.4 degrees Celsius, while the minimum temperature dropped to 5.1degC. IMD officials said westerly winds of around 4.5 kmph prevailed during the early hours and continued through the day. They added that a western disturbance caused by a cyclonic circulation over northern Pakistan triggered core winds of 12.6 kmph or higher.
