Pune and Pimpri-Chinchwad have seen a notable decline in air quality as shifting weather patterns and a recent drop in temperature have led to an increase in pollution levels. The Air Quality Index (AQI) jumped from 75 on October 23 to 133 within 48 hours and stood at 123 by the evening of October 25. Meteorologists at the India Meteorological Department (IMD) predict that dry weather will persist over the next few days, with some light rainfall expected around October 28, which may provide temporary relief. The city experienced satisfactory air quality during the monsoon period from June to September, as consistent rainfall and favourable weather conditions kept pollution at bay. However, dry conditions coupled with a sudden dip in temperatures, especially at night, have led to a noticeable drop in air quality.
Data from SAFAR-IITM underscores this change, showing the highest AQI level in Pune’s Katraj Dairy area at 201 on October 25. Additionally, eight other areas reported AQI levels above 100, marking a moderate pollution category that may impact citizens’ health, particularly among those with respiratory conditions. Night temperatures in Pune dropped from 21.7 degrees Celsius on October 23 to 19.3 degrees Celsius on October 24, leading to increased fog and reduced visibility across the city, a typical occurrence as the season transitions into winter. Senior meteorologists indicate that fog formation due to lower night temperatures is also impacting visibility, which could persist for the next two days before a potential shift in weather.
From a sustainability perspective, the seasonal dip in air quality highlights the need for stronger environmental planning as the city grapples with changing weather. Temporary pollution spikes are becoming a recurring challenge with temperature fluctuations, necessitating adaptive measures to reduce pollution levels, such as stricter vehicle emissions regulations, expanded public transport options, and increased green coverage. For a growing urban area like Pune, sustainable city planning will be crucial to managing these seasonal air quality variations effectively, especially as the city’s development continues to affect air quality.
Civic authorities and urban planners in Pune face mounting pressure to address these pollution fluctuations. As the festive season approaches, higher pollution levels are expected, impacting visibility, respiratory health, and overall air quality. The IMD’s forecast of incoming light rainfall offers a temporary improvement, yet there remains a pressing need for the city to implement proactive measures to ensure air quality management aligns with Pune’s urban development goals. As residents prepare for Diwali, this air quality dip underscores the importance of sustainable practices and environmental consciousness to safeguard public health and the city’s livability.
