About air quality in Asansol
This page tracks the Asansol Air Quality Index using measurements from 4 Central Pollution Control Board (CPCB) monitoring stations, published through the Government of India's open-data portal. Right now Asansol's AQI is 319 (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 Asansol's air changes through the year
Air quality in Asansol changes through the day and across the seasons. Levels are usually worse in the early morning and late evening when cooler, calmer air traps pollutants near the ground, and they tend to rise in the cooler months when inversions are more common; the monsoon typically brings the cleanest air as rain washes particulates away.
What drives air pollution in Asansol
Traffic, construction and road dust, industry and the burning of solid fuels are the main local sources, with regional factors and winter weather adding to the load when the air is calm.
Cleaner and worse areas within Asansol
Air quality is not uniform across a city. Among Asansol's monitoring areas right now, the air is cleanest around Trivenidevi Bhalotia College, Asansol and worst around Asansol Court Area, Asansol — 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 Asansol for cleaner air

Staying safe in Asansol'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.
