Understanding Sivaganga Air Quality
Sivaganga lies in the rain shadow area of the Western Ghats, experiencing a chronically dry climate that affects air quality. The northeast monsoon from October to December is the primary rainy season, but rainfall is often scanty and erratic. When rains do arrive, air quality improves temporarily as dust settles and pollutants are washed out. However, the post-monsoon period from January to February brings the worst air quality as farmers burn crop residues from rainfed cotton, sorghum, and pulse harvests.
Winter months see stable atmospheric conditions that trap pollutants near the surface. Domestic biomass burning for cooking and heating peaks during cooler mornings and evenings, contributing to elevated PM2.5 levels. The town's dependence on groundwater and limited green cover means there's little natural dust suppression. Unpaved roads in outlying areas generate significant PM10 during dry periods.
Summer from March to May is brutally hot, with temperatures frequently exceeding 40°C and sometimes reaching 42-43°C. Extreme dryness creates dust storms that can spike PM10 levels dramatically. Agricultural fields lie fallow and bare, contributing to windblown dust. The town's inland location, about 80 km from the nearest coast, means no sea breeze relief. Water scarcity during these months limits dust control measures, and residents often face combined challenges of heat stress and poor air quality.

Frequently Asked Questions — Sivaganga
Why does Sivaganga have poor air quality despite being a smaller town?
Sivaganga's location in a rain shadow region means limited rainfall and vegetation. The extremely dry climate generates substantial dust pollution, while agricultural burning during winter harvest season and biomass combustion for cooking compound the problem.
How does Sivaganga's dry climate affect its air quality?
The chronic water scarcity and sparse vegetation mean minimal natural dust suppression. Bare agricultural fields, unpaved roads, and limited tree cover result in high PM10 levels, especially during hot, windy conditions from March to May.
