Bengaluru Weather Update: Patchy Showers and Moderate Air Quality Expected on Monday
On Monday, January 26, 2026, Bengaluru is set to experience a warm and slightly humid day, with the likelihood of scattered, intermittent showers. The city's air quality, which was recorded as "moderate" on Sunday, January 25, may see localized improvements due to minimal rainfall and moderate winds. However, residents should remain cautious, as the overall air quality is not expected to undergo a dramatic transformation.
Detailed Weather Forecast for January 26
The temperature in Bengaluru is forecast to range from a high of 25.7°C to a low of 18.6°C, with an average daily temperature of approximately 21.1°C. Humidity levels are predicted to hover around 74%, which could make the air feel somewhat sticky, especially during late morning and early afternoon hours.
Winds are expected to be moderate, reaching speeds of up to 20.9 kmph, which should help alleviate the humidity in open areas. Visibility is anticipated to remain strong at 10 km, indicating no significant haze due to weather conditions alone.
The primary weather highlight for the day is the indication of "patchy rain nearby". The daily chance of rain is noted at 86%, although total rainfall is likely to be light, estimated at roughly 0.27 mm. This suggests brief, localized drizzle rather than sustained rainfall, with a higher probability of "wet road surprises" later in the day when cloud buildup typically peaks.
After sunset at 6:18 PM, temperatures are expected to drop quickly, leading to a comfortable evening with cooler breezes.
Air Quality Report and Analysis
On Sunday, January 25, Bengaluru recorded an AQI-IN of 71, which falls within Category 2, classified as "moderate". On the US scale, this corresponded to an AQI-US of 116. At this level, individuals with asthma, allergies, or heart and lung conditions may experience symptoms such as throat dryness, mild coughing, or a feeling of heaviness during physical exertion.
Particulate pollution was identified as the main concern, with PM2.5 levels recorded at 42 and PM10 levels at 54. Both figures are considered significant during prolonged outdoor exposure, particularly near busy corridors and construction zones. Carbon monoxide (CO) was also present at a level of 303, though particulate matter generally contributes more to day-to-day discomfort for residents.
Today's weather conditions, including light scattered showers and moderate winds, may offer temporary relief by reducing dust and coarse particles. However, given the minimal expected rainfall, a substantial improvement in air quality is not anticipated. Air quality may improve in isolated pockets immediately after a sprinkle but is likely to rebound during peak traffic hours.
Recommendations for Bengaluru Residents
For those stepping out early, it is considered a decent morning for a walk, but keeping a mask handy for stretches with heavy traffic is advisable. In the afternoon, dressing for warmth while ensuring breathability is recommended, as mid-20s temperatures can feel warmer due to humidity. Sunglasses will be beneficial during brighter periods.
Considering yesterday's moderate AQI, wearing a mask is a sensible precaution for long rides or time spent near main roads, especially for pollution-sensitive individuals. Runners and cyclists might find early morning or after sunset more suitable, as the air feels cooler and traffic emissions are typically lower.
Carrying a small umbrella or light rain jacket is also prudent, given the high risk of brief showers today.
Upcoming Week Forecast for Bengaluru
Following today's patchy showers, Bengaluru's weather is set to become distinctly brighter. Tuesday, January 27, is forecast to be sunny and warmer, with temperatures reaching 28.5°C and a cooler low of 17.7°C.
The warming trend is expected to continue from Wednesday to Friday, January 28–30, with highs near 29.6–29.9°C and lows gradually easing down to 16.7°C by Friday. This pattern represents "classic hot afternoons, pleasant nights" weather.
The weekend is also projected to remain sunny. Saturday, January 31, is expected to peak around 29.7°C, and Sunday, February 1, will stay warm near 29.4°C. The coolest low temperature of the entire stretch is anticipated on Sunday, at about 16.2°C.
With little to no rain expected for most of the week, the combination of daytime heat and drying conditions could lead to dust accumulation. Individuals with sensitivities should be mindful of potential afternoon irritation, particularly on days with high traffic.
For outdoor plans, Tuesday and Wednesday appear to be the cleanest and simplest options from a weather perspective, offering sunshine, low rain risk, and comfortable evenings. Today is also suitable for outdoor activities, provided plans account for the possibility of quick showers.
