Seasonal AQI Patterns in Karnataka

❄️Winter (Oct–Feb)~130

Worst season. Temperature inversions, crop burning, and low wind speeds trap pollutants. AQI often exceeds 300 in northern states.

☀️Pre-Monsoon (Mar–Jun)~85

Dust storms and heat raise AQI. Less fog than winter. Industrial activity at peak.

🌧️Monsoon (Jul–Sep)~40

Best air quality of the year. Rain washes out PM2.5 and PM10. AQI typically falls to lowest levels.

🍂Post-Monsoon (Oct)~98

Rapidly deteriorating. Crop stubble burning begins in northern states. AQI transitions from good to dangerous.
