According to the weather forecast, Chennai is in for a wet and humid day on October 27, 2025, with moderate rainfall expected throughout the day. Temperatures are predicted to range between 23.4°C and 24.5°C, with an average of 24.3°C.
The city's air quality, which was recorded as 'good' (AQI 43) the previous day, is expected to improve further due to the rainy conditions. Pollution levels, including PM2.5 at 25 µg/m³ and PM10 at 34 µg/m³, as well as carbon monoxide at 412 µg/m³, were all within acceptable limits.
The combination of good air quality and rainy weather is expected to provide favorable conditions for air purification, benefiting the city's overall environmental health. However, the damp weather may also increase indoor mold growth, necessitating proper ventilation in homes and buildings.
