Delhi recorded 209 'good to moderate' air quality days in 2024, the highest since 2018, barring 2020 which witnessed a sharp dip in pollution due to the COVID-19 lockdown, according to the central pollution watchdog CAQM.
The number of 'good to moderate' air quality days was 159 in 2018, 182 in 2019, 227 in 2020, 197 in 2021, 163 in 2022 and 206 in 2023, Commission for Air Quality Management (CAQM) data showed.
The city had 157 'poor to severe' days this year, the lowest since 2018 when the number stood at 206, excluding 2020 (139 days).
February, December and August recorded the best average Air Quality Index (AQI) in six years.
January, however, suffered the worst air since 2018, hitting an average AQI of 355 due to stagnant winds.
Dry spells and high-speed winds from April to June, especially in May, brought heavy dust and pollution, making it the worst May AQI since 2018, the CAQM said.
Despite this, 2024 tied with 2021 and 2022 for the second-best annual average AQI of 209, it said.
The year also saw a significant drop in stubble burning. Farm fires fell to 12,750 in Punjab, Haryana and neighbouring areas, the data showed.

India pays for toxic air every year, through lost wages, hospital bills and slower growth, writes Dr. Sabine Kapasi.
Pneumonia starts when an infection reaches the lungs and causes inflammation. The immune system responds to the infection, causing the air sacs to become inflamed and fill with fluid or pus. As the lungs become affected, oxygen exchange becomes harder.
Exposure to pollutants can harm your child's developing lungs and trigger symptoms such as cough, blocked nose, shortness of breath, and a scratchy throat.
Mumbai recorded an AQI of 154, in the poor category, with PM2.5 at 76 g/m and PM10 at 130 g/m, despite sunny skies and 28 degrees Celsius.
