About air quality in Bengaluru
This page tracks the Bengaluru, Karnataka Air Quality Index using measurements from 9 Central Pollution Control Board (CPCB) monitoring stations, published through the Government of India's open-data portal. Right now Bengaluru's AQI is 352 (Very Poor), with PM2.5 the dominant pollutant. The AQI is a single number from 0 to 500 that summarises how polluted the air is and what it means for health, built from pollutants such as fine particulate matter (PM2.5), coarse particulate matter (PM10), nitrogen dioxide, ground-level ozone and sulphur dioxide — the index reflects whichever is worst at the time.
How Bengaluru's air changes through the year
As a southern city, Bengaluru generally enjoys cleaner air across the year than the northern plains, helped by sea breezes and weaker winter inversions. Dust and ground-level ozone can rise during the hot, dry pre-monsoon weeks, while the monsoon brings the freshest air of the year. The daily rhythm still matters — mornings and evenings are usually worse than a breezy afternoon.
What drives air pollution in Bengaluru
Traffic, construction and road dust, industry and port or coastal activity are the main local sources. Sea breezes and stronger winds usually help disperse pollution, which is why coastal air often clears faster than in landlocked cities, though calm days and dry-season dust can still push readings up.
Cleaner and worse areas within Bengaluru
Air quality is not uniform across a city. Among Bengaluru's monitoring areas right now, the air is cleanest around Jayanagar 5th Block, Bengaluru and worst around Silk Board, Bengaluru — a reminder that local traffic, industry and construction can make a real difference over just a few kilometres. The live area-by-area comparison above shows where to go and where to avoid at this moment.
Best time to visit Bengaluru for cleaner air
For the cleanest air, the monsoon and the months just after it are usually best in Bengaluru, while the driest, stillest weeks can be worse. Check the live reading on this page before outdoor exercise or sightseeing, and keep an N95 mask handy for high-pollution days.
Staying safe in Bengaluru's air
When the AQI is in the Good or Satisfactory range, outdoor activity is fine for almost everyone. From Moderate upward, sensitive groups — children, older adults, pregnant people and anyone with asthma or heart disease — should pace themselves outdoors, and once the air turns Poor or worse it is sensible for everyone to limit strenuous outdoor exertion, keep windows closed, run an air purifier indoors and wear a well-fitting mask outside. This is general information rather than medical advice. We only display a number when a recent station reading exists — if you see "data updating", we are waiting on a fresh value rather than showing an estimate.
