दिल्ली-एनसीआर का कल का AQI — estimated air quality for the last 24 hours, tomorrow and the next few days across Delhi, Noida, Gurugram, Ghaziabad, Faridabad and Meerut.
AQI values on this site are estimates on India's CPCB National Air Quality Index scale, calculated from 24-hour average PM2.5 and PM10 forecast by the Copernicus Atmosphere Monitoring Service (via Open-Meteo). They are model data for a wide grid area, not readings from a specific monitoring station — for official values, see CPCB. Read more on our Data Sources page.
During the pollution season, the Commission for Air Quality Management (CAQM) invokes GRAP stages for Delhi-NCR based on the AQI. Each stage adds restrictions on top of the previous one. The table shows the AQI ranges that usually trigger each stage — always check CAQM's latest order for the exact rules in force.
| Stage | AQI | Typical measures |
|---|---|---|
| Stage I | 201–300 (Poor) | Dust control at construction sites, restrictions on open burning, strict enforcement of pollution checks for vehicles. |
| Stage II | 301–400 (Very Poor) | Limits on diesel generator use, more frequent road cleaning and water sprinkling, higher parking fees to discourage private vehicles. |
| Stage III | 401–450 (Severe) | Ban on non-essential construction and demolition, restrictions on older petrol and diesel cars, possible shift of primary classes to online mode. |
| Stage IV | Above 450 (Severe+) | Entry restrictions on most trucks, ban on all construction including public projects, and advisories for work from home and school closures. |
| AQI | Category | Possible health impact (CPCB) |
|---|---|---|
| 0–50 | Good | Minimal impact. |
| 51–100 | Satisfactory | Minor breathing discomfort for sensitive people. |
| 101–200 | Moderate | Breathing discomfort for people with lung disease such as asthma, and discomfort for people with heart disease, children and older adults. |
| 201–300 | Poor | Breathing discomfort for most people on prolonged exposure. |
| 301–400 | Very Poor | Respiratory illness on prolonged exposure. |
| 401–500 | Severe | Affects healthy people and seriously impacts those with existing diseases. |
The Delhi card at the top of this page shows the estimated AQI for the last 24 hours, tomorrow and the following days, calculated from PM2.5 and PM10 forecasts. For official readings, check CPCB's SAMEER app or website.
Cold, calm weather and low temperature inversions trap pollutants close to the ground, while local emissions from vehicles, industry, construction dust and waste burning continue. Crop-residue burning in Punjab and Haryana adds smoke in late October and November, and Diwali fireworks can cause short spikes.
The Graded Response Action Plan is a set of emergency measures for Delhi-NCR, enforced by the Commission for Air Quality Management (CAQM). Stages are triggered by AQI levels — from Stage I at 'Poor' to Stage IV at 'Severe+' — and bring restrictions such as bans on construction, certain vehicles and diesel generators. CAQM announces the exact stage and rules in force.
Limit outdoor exercise, especially early morning and late evening when pollution is often highest; wear a well-fitting N95 or N99 mask outdoors; keep windows closed at peak hours; use an air purifier if you can; and follow your doctor's advice if you have asthma, heart or lung conditions.
