Residents in the city began their day on 18 November 2025 with cool, damp weather and the likelihood of patchy rain through the day. Data sourced from AQI.in indicates that the city is experiencing mild temperatures alongside moderate air quality, prompting residents to plan their activities with both weather and pollution levels in mind.

A mild start to a drizzly Bengaluru day

Bengaluru opened to a pleasant morning at 18.5°C — a temperature that many would find ideal for an early walk or a warm cup of chai on the balcony. As the day progresses, temperatures are expected to rise gently to a high of around 22.2°C.

Cloudy skies are likely to dominate throughout the day, with limited sunshine expected. Meteorological data shows an 87% chance of rain, making it prudent for commuters and outdoor-goers to keep an umbrella or rain jacket handy, especially during the late afternoon hours.

Humidity is set to remain high at about 86%, causing the atmosphere to feel heavier and slightly sticky. Light winds of around 19.1 km/h will flow across the city, with a particularly cool breeze anticipated after 9 PM.

Air quality remains moderate after yesterday’s readings

Bengaluru’s air quality on Monday remained in the ‘moderate’ category, registering an AQI of 103. This reading, typical for a high-traffic urban setting, was driven mainly by PM2.5 levels at 57 µg/m³ and PM10 levels at 85 µg/m³.

While these levels are not categorised as hazardous, individuals with respiratory sensitivities may have experienced mild discomfort, especially during peak commuting hours.

With today’s forecasted spells of rain, there is the possibility of some atmospheric cleansing, which may help marginally improve pollutant concentrations through the day. However, lingering vehicular emissions and construction dust in crowded pockets may still affect localised air quality.

What residents should keep in mind today

Given the combination of rain and high humidity, residents are advised to plan their day with a few precautionary measures:

  • Carry a compact umbrella or waterproof jacket to stay dry during expected showers.
  • Opt for lightweight, breathable clothing to stay comfortable in humid conditions.
  • Consider wearing a mask if travelling through busy intersections or high-traffic corridors, where pollution levels tend to spike.
  • Enjoy the cool weather indoors — those working from home may find it an ideal day to settle in with a book or a hot beverage as rain clouds linger outside.

Week-long outlook shows mixed weather ahead

The coming week promises a varied mix of sunny and rainy spells. Tuesday and Wednesday are expected to see patchy rainfall, with temperatures ranging between 19.4°C and 26.9°C.

By Thursday and Friday, clearer skies are expected, bringing warmer conditions with temperatures rising to 27.2°C and 25°C respectively.

Saturday will likely bring back moderate rainfall, which may disrupt outdoor plans. Meanwhile, Sunday is forecast to be cooler at 18.8°C, with a slight chance of showers resurfacing.

These fluctuations mark a shift away from the warmer days seen recently, signalling the gradual return of Bengaluru’s cooler mornings and evenings. Notably, yesterday’s AQI reading—though moderate—was an improvement over last week’s average, hinting at slowly stabilising air conditions.

Conclusion

Bengaluru residents can expect a pleasantly cool, rain-kissed day with moderate air quality that may improve slightly with the anticipated drizzle. With mixed weather patterns forecast for the week ahead, planning for fluctuating temperatures and rainfall will help ensure smoother daily routines.
