The city is set to experience heavy rainfall on Thursday, September 19, 2025, with temperatures ranging between 19.8°C and 25.2°C. While the high humidity of 87% may create discomfort for residents, the downpour is expected to further improve Bengaluru’s already encouraging air quality.
Detailed weather conditions
The day will start with a morning temperature of 19.8°C and rise to a maximum of 25.2°C by afternoon. According to forecasts, there is a 93% chance of heavy showers throughout the day, accompanied by moderate winds blowing at 18 km/h.
Visibility will be reduced to 8.1 km under overcast skies, with rainfall intensity expected to pick up in the afternoon and evening. Night temperatures will dip slightly, bringing some relief from humidity, along with a gentle breeze.
Air quality report
Bengaluru recorded an AQI of 41 on Wednesday, one of the city’s lowest pollution levels this month. By US standards, the AQI stood at 59. Key pollutants included PM2.5 at 14 µg/m³, PM10 at 41 µg/m³, and carbon monoxide at 399 µg/m³.
The expected rainfall will likely wash away suspended particles and help maintain or improve these conditions further. Experts note that the combination of good AQI readings and continued rain reflects a positive trend in Bengaluru’s environmental conditions.
Travel and comfort advisory
Authorities have advised residents to minimise outdoor travel during the heavy downpour. Those stepping out should carry umbrellas, wear waterproof footwear, and avoid waterlogged routes.
Light cotton clothing is recommended, though the high humidity may still cause indoor discomfort. Dehumidifiers or proper ventilation are suggested for households to maintain comfort levels indoors.

Sep 20–21: Moderate showers; temperatures between 19°C and 26°C.
Sep 22–23: Patchy rainfall with humid conditions.
