Bengaluru residents woke up to some good news on Saturday, five days after Diwali, as the city recorded one of the cleanest air quality levels among major metros in India. The city’s Air Quality Index (AQI) stood at 32 in the morning, indicating healthy and breathable air. Hyderabad followed closely with an AQI of 45, and Chennai also recorded good air quality at 56.

In contrast, northern cities are still battling heavy pollution. Delhi’s AQI reached 336 at 9:30 am on Saturday, placing it in the very poor category, while visibility in the national capital region remained low due to a thick layer of smog, said a report by The Indian Express. Ahmedabad was the only other major city with AQI levels above 150, showing unhealthy air.

For residents in Bengaluru, the relatively clean air offers relief, but experts cautioned that seasonal changes and traffic pollution could still impact air quality. Health officials recommended regular monitoring, especially for sensitive groups like children and the elderly, although the city’s current levels make outdoor activities like walking, jogging, or cycling safer than in other metros.

The AQI system ranges from Good (0–50) to Severe (401–500), with higher readings indicating worse air quality. While Delhi has had to activate anti-smog measures, including spraying water using anti-smog guns, Bengaluru’s comparatively low pollution means residents can enjoy the outdoors with less worry.

With winter setting in and firecracker pollution fading, Bengaluru continues to enjoy some of the cleanest air among India’s big cities, making it a rare bright spot in the country’s post-Diwali pollution scenario.
