Experts indicate that persistent rain will continue to support improved air quality, particularly in high-traffic urban zones.
Authorities recommend that citizens, particularly those with respiratory conditions, continue taking precautions, including mask usage and avoiding prolonged outdoor exposure during rainfall. The combination of moderate temperatures, consistent showers, and improving AQI levels contributes to a relatively comfortable climate despite high humidity.Environmental experts emphasise that urban rain patterns not only aid air quality but also support sustainable water management across Chennai. Continuous monitoring of rainfall, air quality, and humidity levels remains critical for residents to manage health and daily activities efficiently.As Chennai continues to witness rainfall and moderate weather conditions, experts believe that the city is experiencing one of its more stable seasonal patterns, enhancing both public health and environmental resilience.
