Lucknow Air Quality Index
Lucknow, the City of Nawabs and capital of Uttar Pradesh, sits at the heart of the Indo-Gangetic Plain — one of the world's most polluted air sheds. With annual average AQI exceeding 200 and winter months regularly hitting hazardous levels, Lucknow is consistently among India's most polluted major cities.
Monthly AQI Pattern
⚠️ Health Alert: October–March
Lucknow's winter air (October through March) poses a serious health risk. During this period, vulnerable populations — children, elderly, pregnant women, and those with respiratory or cardiovascular conditions — should minimize outdoor exposure. Use N95 masks when outdoors, run HEPA air purifiers indoors, and seal windows during peak pollution events (early morning and evening).
Frequently Asked Questions
What is Lucknow's AQI in 2024?
Lucknow's annual average AQI in 2024 is approximately 216 (Very Unhealthy). As the capital of Uttar Pradesh and the heart of the Indo-Gangetic Plain, Lucknow is trapped in one of the world's worst pollution zones. During November–January, AQI frequently exceeds 400 (Hazardous) for weeks at a time.
Why is Lucknow's air quality so terrible in winter?
Lucknow sits at the epicenter of the perfect pollution storm: (1) Indo-Gangetic Plain topography — the Himalayas to the north block cold Arctic air, creating temperature inversions that trap pollution at ground level. (2) Crop burning — October–November sees massive wheat/rice stubble fires from neighboring Haryana, Punjab, and UP districts. (3) Dense urban density with old vehicle fleet, brick kilns, and industrial activity, all suspended in stagnant winter air.
How does crop burning affect Lucknow?
Lucknow is directly downwind of both Punjab/Haryana stubble fires (October) and UP's own crop burning areas. Satellite imagery shows smoke plumes from hundreds of simultaneous fires blanketing the entire IGP from Delhi to Varanasi. In Lucknow, crop fire days push PM2.5 to 300–600 μg/m³ — 10–20× the safe limit of 25 μg/m³. The smoke events last 3–6 weeks annually.
What are the health impacts of living in Lucknow?
Studies from King George's Medical University, Lucknow show significantly elevated rates of chronic obstructive pulmonary disease (COPD), bronchial asthma, and cardiovascular disease compared to cleaner Indian cities. Annual PM2.5 exposure in Lucknow (averaging ~80 μg/m³) reduces life expectancy by an estimated 5–7 years compared to WHO guideline compliance. Children show measurably reduced lung function growth.
Is there any period when Lucknow air is safe?
July and August during peak monsoon season are Lucknow's only genuinely safe months — rainfall continuously washes out particulates, AQI drops to 60–75. Early September can also be acceptable. For the remaining 8–10 months, AQI is elevated to concerning levels, with 4–5 months being genuinely dangerous for sensitive groups.
