What you can do outside right now
General guidance by AQI band. Sensitive groups should act one level earlier.
Live pollutant levels
Each pollutant's 24-hour concentration is converted to a CPCB sub-index; the city AQI is the highest of them (the dominant pollutant). Bars show the sub-index out of 500.

AQI categories (India scale)
| AQI | Category | Associated health impact |
|---|---|---|
| 0–50 | Good | Air quality is considered satisfactory and air pollution poses little or no risk. |
| 51–100 | Satisfactory | Acceptable air quality; minor breathing discomfort possible for unusually sensitive people. |
| 101–200 | Moderate | May cause breathing discomfort to people with lung disease such as asthma, and to children and older adults. |
| 201–300 | Poor | May cause breathing discomfort to most people on prolonged exposure. |
| 301–400 | Very Poor | May cause respiratory illness on prolonged exposure; effects more pronounced for people with lung and heart disease. |
| 401–500 | Severe | Affects healthy people and seriously impacts those with existing diseases; avoid outdoor activity. |

About air quality in Siliguri
This page tracks the Siliguri Air Quality Index using measurements from a Central Pollution Control Board (CPCB) monitoring station, published through the Government of India's open-data portal. Right now Siliguri's AQI is 89 (Satisfactory), with PM10 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 Siliguri's air changes through the year
Air quality in Siliguri 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 Siliguri
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.
Best time to visit Siliguri for cleaner air
For the cleanest air, the monsoon and the months just after it are usually best in Siliguri, 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. Nearby cities with comparatively cleaner air right now include Madikeri, Srinagar, Thoothukudi.
Staying safe in Siliguri'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.
