According to the India Meteorological Department (IMD), the day brings an 85% chance of precipitation, accompanied by high humidity at 79%, which may make conditions feel muggy throughout the day.

Air quality and pollution levels

Bengaluru recorded a moderate Air Quality Index (AQI) of 75 yesterday. Key pollutants included PM2.5 at 18 µg/m³ and PM10 at 75 µg/m³. Carbon monoxide levels were measured at 358 µg/m³, which are within acceptable limits but may cause mild discomfort to individuals with respiratory sensitivities. Experts note that the ongoing rainy season is helping reduce dust and pollutants in the air, though high humidity may trap some particulate matter.
