AQI levels in Bengaluru have been above “poor” and “unhealthy” levels since October, especially due to the winter effect combined with Deepawali celebrations. An official from the Karnataka State Pollution Control Board (KSPCB) had said natural air purification was being prevented by the cloud cover, which does not allow wind movement. Air quality in the city is expected to go up to healthier levels if clear skies persist.

According to the air quality forecast, Bengaluru AQI levels could be at 128 on Saturday and ease to levels below 100 thereafter.
