Today's Air Quality Snapshot
Lucknow is currently experiencing a 'Poor' air quality day, with the Air Quality Index (AQI) standing at 161. This level indicates that the air is unhealthy for sensitive groups, and the general population
may begin to experience health effects. The primary contributors to this rating are elevated levels of Particulate Matter, specifically PM2.5 measuring at 78 µg/m³ and PM10 at 91 µg/m³. Additionally, Carbon Monoxide is present at a significant concentration of 510 ppb, and Ozone is recorded at 10 ppb. For individuals with pre-existing respiratory conditions, it is strongly advised to limit outdoor activities to minimize exposure to these harmful pollutants. The current temperature in the city is 28°C, which can influence air pollutant dispersal.
Major Air Pollutants Explained
The air in Lucknow today is predominantly impacted by several key pollutants. Chief among these are Particulate Matter 2.5 (PM2.5) and Particulate Matter 10 (PM10). PM2.5 particles, with a diameter of less than or equal to 2.5 micrometers, are fine enough to penetrate deep into the lungs and even enter the bloodstream, posing significant health risks. Lucknow's PM2.5 level is currently at 78 µg/m³. PM10 particles, larger than PM2.5 but still inhalable, measure at 91 µg/m³ and affect the upper respiratory tract. Carbon Monoxide (CO) is another concerning pollutant, registering at a high 510 ppb; this odorless, colorless gas reduces the blood's ability to carry oxygen. Other pollutants noted include Sulphur Dioxide (SO2) at 3 ppb, Nitrogen Dioxide (NO2) at 11 ppb, and Ozone (O3) at 10 ppb, though PM and CO are the primary drivers of the current 'Poor' AQI.
Weekly Air Quality Trends
Examining the air quality trend over the past week in Lucknow reveals a fluctuating, yet predominantly 'Poor' status. On March 12th, the AQI was recorded at 160, also in the 'Poor' category. The following day, March 13th, saw a slight increase to 163, remaining 'Poor'. A brief improvement occurred on March 16th, when the AQI dropped to 96, falling into the 'Moderate' category. However, this respite was short-lived. Air quality deteriorated significantly by March 18th, reaching a high of 190, the peak 'Poor' reading for the recorded period. The data from March 12th to March 18th, 2026, shows that Lucknow has consistently struggled with air quality issues, with most days falling within the 'Poor' classification, highlighting a persistent environmental concern for the city's residents.
