Key Facts
1. What AQI 212 Means
An AQI of 212 is classified as “poor.” Prolonged exposure can cause breathing issues, coughing, or irritation in the eyes and throat. Sensitive groups like children, the elderly, and asthma patients are most at risk.

- Mazgaon: AQI ~309 (very poor)
- Malad West: AQI ~290 (poor)
- Chembur: AQI ~280 (poor)
3. Causes of Pollution Spike
- Firecracker Smoke: Sulphur dioxide, nitrogen oxides, and particulate matter released from crackers accumulated overnight.
- Stagnant Weather: Weak winds and moisture trapped pollutants near the ground.
- Pre-Existing Emissions: Vehicle exhaust and construction dust had already raised baseline AQI levels before Diwali.
4. Meteorological Influence
A temperature inversion during the night prevented pollutant dispersion, forming a dense smog layer that lingered until sunlight and mild sea breeze began to disperse it by late morning.

- Environmental Impact: Diwali emissions significantly offset months of environmental progress.
- Behavioral Lesson: The data demonstrates that responsible celebration is essential for urban air management.
Comparisons
| Year | Average Post-Diwali AQI | Category | Trend |
|---|---|---|---|
| 2023 | 185 | Moderate–Poor | Improving |
| 2024 | 198 | Poor | Slight rise |

Expert Analysis
Environmental specialists classify the Mumbai air quality after Diwali 2025 AQI 212 event as a “weather-pollution convergence.”
