Warmer Diwali Leads to Faster Pollution Clearance in Lucknow
25 Oct, 2025
Summary
- Diwali celebrations saw higher temperatures, reducing pollution
- Minimum temperatures expected to drop by 2-3°C in next 48 hours
- Cyclonic storm to partially affect Uttar Pradesh in coming days
As of October 25, 2025, the Diwali celebrations in Lucknow this year saw higher than normal temperatures, which appears to have helped in reducing pollution levels caused by firecrackers. Experts explain that the warmer conditions prevented heat traps and haze, allowing pollutants to clear quickly on the night after Diwali.
The state's minimum temperature is now expected to fall by 2 to 3°C over the next 48 hours, due to the absence of any active weather system. However, a low-pressure area formed in the southeastern Bay of Bengal is set to move west-northwestward, strengthen, and intensify into a cyclonic storm over the southwest and adjoining west-central Bay of Bengal by October 27, partially affecting the state.
Clouds are expected to return to parts of Uttar Pradesh three days later, leading to a drop in maximum temperatures. Scattered rainfall is also likely in the southeastern districts on October 29 and 30, as the weather system fully develops.
