Summary:
This is a short article published in “The Hindu” on October 23, 2025, discussing how overcast, humid weather conditions worsen air pollution caused by firecrackers. It explains that the combination of pollutants released by fireworks (particulate matter, carbon dioxide, etc.) and the weather (low mixing height, water vapor) traps the pollutants near the ground, creating a toxic haze.

Indian Cities Brace for Heightened Air Pollution as Deepavali Looms Amidst Overcast Skies
NEW DELHI, October 23, 2025 – With Deepavali celebrations approaching, experts at The Hindu are warning of potentially hazardous air quality in regions experiencing overcast and humid weather conditions. According to a report released this morning, the combination of pollutants released by firecrackers and specific atmospheric conditions can create a significantly more toxic environment than on a clear day.
The article highlights the dangers of particulate matter (PM), carbon dioxide, carbon monoxide, nitrogen oxides, and sulphur dioxide emitted by firecrackers. These substances, when released during celebrations, can drastically reduce air quality and visibility, leading to what experts are calling a “toxic haze.”
The presence of overcast skies, characterized by cooler temperatures and a lower mixing height in the atmosphere, prevents pollutants from dispersing effectively. “Most smog episodes coincide with cloudy skies,” the report states, emphasizing the importance of this atmospheric condition.
High humidity further exacerbates the problem. Water vapor in the air can interact with pollutants, forming secondary pollutants such as acid rain. Additionally, humidity contributes to fog and haze, which can trap particulate matter and other pollutants, preventing their dispersal.
The report serves as a stark reminder of the environmental impact of traditional Deepavali celebrations. As the festival approaches, public health officials are urging citizens to be mindful of their actions and consider alternative, less polluting ways to celebrate.
