Pune Air Quality Index
Pune, Maharashtra's education and IT capital, has a natural bowl geography that creates challenging air quality conditions especially in winter. With over 4 million registered two-wheelers and the industrial Pimpri-Chinchwad zone upwind, Pune's moderate annual AQI masks significant winter pollution spikes.

Frequently Asked Questions
What is Pune's AQI in 2024?
Pune's annual average AQI in 2024 is approximately 89 (Moderate). The city sits in a bowl geography surrounded by the Sahyadri ranges, which limits wind-driven dispersion during winter months. November and December consistently see AQI 100–130, primarily due to Diwali firecrackers, post-harvest burning in Marathwada, and winter inversions.
Why are two-wheelers such a big problem in Pune?
Pune has one of the highest two-wheeler-to-population ratios in India — approximately 1 two-wheeler for every 2 residents. Two-wheelers running on older BS4 and earlier engines emit disproportionate PM2.5 and hydrocarbons per km traveled versus cars. The IT and education sectors drive massive daily commuting on two-wheelers, making them Pune's primary mobile pollution source.
How does PCMC (Pimpri-Chinchwad) affect Pune's air quality?
Pimpri-Chinchwad Municipal Corporation, the industrial twin of Pune, hosts India's largest auto manufacturing cluster: Tata Motors, Bajaj Auto, Force Motors, and 300+ ancillary units. Industrial emissions from PCMC frequently drift southeast into Pune city during northeast winter winds. PCMC's PM10 readings are typically 20–30% higher than Pune city proper.
Is Pune air quality better or worse than Mumbai?
Pune and Mumbai have similar annual averages, but different profiles. Mumbai's air is dominated by shipping/port diesel, sea salt aerosols, and coastal industrial zones. Pune's pollution is more land-based: two-wheelers, construction, PCMC industry, and seasonal burning. During winter, Pune can actually be worse than coastal Mumbai, which benefits from sea breeze dispersion.
When is Pune air quality worst?
November is typically Pune's worst month. Diwali fireworks create a 3–5 day PM2.5 spike (often 200–300+ μg/m³), followed by crop residue burning smoke from Marathwada and Vidarbha drifting west. December–January winter inversions then trap this pollution. Daily AQI of 120–150 is common during November evenings.
