Met factors help, Gurgaon’s air quality better as Delhi chokes on smoke

According to data from the Central Pollution Control Board, while Delhi’s air quality index stood at around 370 (‘very poor’), Gurgaon's was at 238 (‘poor’) thanks to winds and terrain easing pollution there.

Despite data gaps, Gurgaon's October AQI this year worse than last 2

This October seemed to promise clean air, with the average air quality index (AQI) remaining below 200 (moderate) in the city. But with most monitoring stations going dark throughout the month, a true picture of AQI is guesswork. Gurgaon ended Oct with an AQI of 195 on Friday. At first glance, this might appear to be an improvement, but Gurgaon saw a decline in air quality going by the data.
