In a welcome change for residents long accustomed to smog-filled skies, Delhi recorded its cleanest air in nearly two years on Tuesday, with the Air Quality Index (AQI) slipping into the ‘good’ category a rare occurrence for the city. The 24-hour average AQI stood at 51 by 4 PM, according to the Central Pollution Control Board (CPCB), a level not seen since September 10, 2023, when it dropped to 45.
The significant improvement comes as persistent rain and steady winds helped flush out pollutants from the air. In the early part of the day, the AQI hovered between 48 and 50, comfortably within the ‘good’ range a classification the capital seldom achieves outside of the monsoon season.
Meteorologists from the India Meteorological Department (IMD) attributed the clean air to continuous light to moderate showers that have cooled the capital and suppressed dust and emissions. The rainfall, coupled with relatively lower temperatures and consistent wind flow, created ideal atmospheric conditions for air purification.
This cleaner air marks a momentary but much-needed relief in a city where air pollution often breaches hazardous levels, particularly in winter. Experts have often pointed out that Delhi’s monsoon months typically July through September are the only period when the capital occasionally meets safe air quality standards.
Officials hope that with more rainfall expected in the coming days, Delhi might sustain its improved air quality for a little longer. However, environmentalists caution that this window is temporary and must be seen as an opportunity to push for long-term pollution control measures rather than a seasonal reprieve.
For now, though, the city breathes easier quite literally under clearer skies.
