Bengaluru:The city is set to experience moderate to heavy rainfall on Monday (September 22, 2025), with temperatures expected to hover between 20.4°C and 26.5°C. According to AQI.in, the rainfall, accompanied by cloudy skies and a 95% chance of precipitation, will improve Bengaluru’s air quality, which was already recorded at a “good” level with an AQI of 48 on Sunday.

Rain and traffic disruptions expected

The day will be marked by consistent showers, high humidity of 82%, and winds reaching up to 18 km/h. While this offers some relief from sultry conditions, commuters have been advised to prepare for slippery roads, waterlogging, and extended travel times. Reduced visibility is also likely to affect peak-hour traffic.

Improved air quality

Sunday’s air quality data showed PM2.5 at 17 µg/m³ and PM10 at 48 µg/m³, while carbon monoxide levels stood at 338 µg/m³. These levels indicated largely comfortable breathing conditions, though sensitive groups may have experienced minor irritation. Experts note that today’s rain will likely further reduce pollutant concentrations, offering a healthier environment for outdoor activities in the mornings.

Forecast for the week ahead

The coming days will continue to see varied rain patterns.

  • September 23: Patchy rain, with a maximum of 26.6°C.
  • September 24: Heavier showers expected, alongside lower temperatures.
  • September 25–28: Consistent rainfall predicted, with maximum temperatures ranging from 23.7°C to 25.8°C.

September 23 is expected to be the most suitable day for outdoor activities due to lighter rainfall, while September 27 could see increased wind activity, making indoor plans preferable.

Advisory for residents

Residents are advised to carry rain protection gear, wear light outerwear in the evenings, and avoid traffic-heavy areas wherever possible. With persistent rainfall and moderate winds, planning ahead for commuting and outdoor schedules will help minimise disruptions.

A relief for sensitive groups

The consistently low pollution readings this week are expected to benefit residents with respiratory sensitivities. The combination of rain and wind will help keep the city’s air fresh, marking one of the lowest AQI levels of the month.
