Bengaluru: Residents of the city can expect moderate rainfall throughout Saturday, October 19, 2025, with temperatures hovering between 20.5°C and 26.2°C, according to forecasts. The air quality index (AQI) stood at 53 on Friday, placing it in the ‘moderate’ category. Today’s outlook predicts a 96% chance of rain, with humidity levels at 85% and wind speeds reaching 16.6 km/h.

Increasing rainfall expected by afternoon

Meteorologists indicate that rainfall intensity will likely increase as the day progresses, especially during the late afternoon and evening hours. Despite cooler temperatures, the high humidity may create a muggy atmosphere across several parts of the city.

Residents have been advised to carry umbrellas and wear waterproof footwear as intermittent showers may continue throughout the day.

Pollution levels show improvement

Yesterday’s pollution data recorded PM2.5 at 22 µg/m³, PM10 at 52 µg/m³, and CO levels at 528 µg/m³. While these levels pose minimal risk to the general public, experts caution that individuals with respiratory sensitivities may still experience mild discomfort.

The improvement in Bengaluru’s AQI represents one of the cleaner air quality days this month. Weather analysts attribute this to the ongoing rainfall, which helps disperse pollutants in the atmosphere.

Advisories for residents

Given the combination of high humidity and active rainfall, residents are encouraged to:

  • Carry umbrellas or raincoats during commutes
  • Opt for waterproof footwear to avoid slipping
  • Wear masks in high-traffic areas where pollution and humidity may combine to affect air quality

Civic authorities have also urged commuters to exercise caution on waterlogged stretches and low-lying areas.

Week-long weather outlook

According to forecasts, moderate rainfall will persist into the early part of next week.

  • October 20–21: Continued moderate showers with temperatures between 19.9°C and 26.5°C.
  • Midweek (October 22–24): Rain intensity expected to decline, giving way to patchy showers and slightly cooler conditions, with temperatures ranging from 19.4°C to 23.6°C.
  • Weekend of October 25: Minimal rainfall predicted, offering improved conditions for outdoor activities and travel plans.

Rain-linked air quality improvement

The current AQI of 53 marks a notable drop in pollution compared to earlier in October, when particulate matter levels were consistently higher. Meteorologists expect continued rain to further cleanse the city’s air, enhancing visibility and comfort levels.
