About air quality in Karnataka
This page tracks live air quality across Karnataka using Central Pollution Control Board (CPCB) monitoring stations, published through the Government of India's open-data portal. Each city's Air Quality Index is computed from fine particulate matter (PM2.5), coarse particulate matter (PM10) and other pollutants; the higher the number, the greater the health concern. Air quality varies widely within a state — by city, by time of day, and by season — so open any city above for its live reading, pollutant breakdown, health advice and 7-day trend.
Across much of India, air quality is worst in the cooler months (roughly October to February), when temperature inversions and seasonal burning trap pollutants near the ground, and cleaner during the monsoon. Check the current figures before outdoor activity rather than relying on the season alone.
