What drives air pollution in Surat

The dominant pollution sources affecting India cities like Surat are:

• vehicle exhaust (especially diesel autos and trucks)
• coal-fired power plants and brick kilns
• agricultural stubble burning in autumn (Oct-Nov)
• construction dust
• open municipal waste burning
• biomass cooking fuel in lower-income households

Seasonal pattern

Air quality typically worsens dramatically October through February, when temperature inversions trap pollutants close to ground level and crop-residue burning peaks. The monsoon (June-September) usually brings the cleanest air.

Geography and meteorology

Surat sits at approximately 21.17° latitude, 72.83° longitude. The Indo-Gangetic Plain's flat topography and Himalayan barrier to the north create textbook conditions for pollution accumulation. Cool, calm winter mornings let particulates concentrate over multiple days.

Health implications

Sensitive groups should monitor daily readings. Plan outdoor activity for cleaner-air windows. The most-studied pollutant for population health is fine particulate matter (PM2.5). Exposure is linked to cardiovascular disease, respiratory illness, and increased mortality. Children, the elderly, and people with respiratory or cardiac conditions face elevated risk.

Other pollutants commonly elevated in urban areas:

• Ozone (O3) - peaks on hot, sunny afternoons
• Nitrogen dioxide (NO2) - traffic-correlated, peaks at rush hours
• PM10 - includes road dust and coarse particles

Policy and trajectory

Government responses have included Graded Response Action Plans, vehicle restriction schemes, and stubble-management subsidies. Enforcement is inconsistent and air quality during peak winter months remains hazardous in major centers.

Practical guidance for residents and visitors

1. Check the AQI before outdoor exercise. If readings exceed 100, sensitive groups should reduce intensity. Above 150, everyone should consider shifting indoors.
2. Wear an N95 or KN95 during peaks. Cloth masks do not filter PM2.5.
3. Run a HEPA air purifier in bedrooms. Indoor levels typically track 50-70% of outdoor levels in unfiltered homes - see our air purifier buyer's guide.
4. Use mechanical ventilation with HEPA filtration when AQI is high; avoid simply opening windows.
