About air quality in Ludhiana
This page tracks the Ludhiana, Punjab 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 Ludhiana's AQI is 378 (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 Ludhiana's air changes through the year
As a North Indian city, Ludhiana sees the country's sharpest seasonal swing. From roughly late October to February, cool and still air with temperature inversions traps emissions close to the ground, and smoke from post-harvest crop-residue burning in Punjab and Haryana — together with festival-season activity around Diwali — pushes the AQI to its yearly peak. The monsoon (June to September) usually brings the cleanest air as rain washes particulates out, with spring and early autumn sitting in between.
What drives air pollution in Ludhiana
The main contributors are vehicle exhaust, road and construction dust, industry and power generation, household cooking and heating fuel, and — in the cooler months — seasonal crop-residue burning across the surrounding farmland. Because the region is landlocked, there is little sea breeze to flush pollutants away, so they accumulate night after night during still winter spells.
Best time to visit Ludhiana for cleaner air
If cleaner air matters for your visit, the smog season from November to January has Ludhiana's worst air of the year, while the monsoon and the weeks around it, along with spring, are usually far better. Whatever the month, check the live reading on this page before heading out, and pack a well-fitting N95 or FFP2 mask for high-pollution days. Nearby cities with comparatively cleaner air right now include Amritsar.
Staying safe in Ludhiana'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.
