The forecast indicates firmly sunny conditions throughout the day. This includes comfortable daytime warmth and a distinctly cooler morning and late evening.Air quality, however, was not at its best yesterday. The Air Quality Index (India) registered 86, which falls into the moderate bracket.Sensitive groups may still feel some throat or eye irritation today, especially near busy roads.If stepping out early, it presents a pleasant window for a walk.However, keeping a light mask handy for traffic-heavy stretches is not considered a bad idea.
Today’s Weather
Today’s weather is characterized by a sun-drenched afternoon, with a cool start and finish.The city expects a high temperature of 27.2 degrees Celsius. The low temperature is forecast at 14.5 degrees Celsius. The average temperature for the day is around 20.3 degrees Celsius.This temperature range is described as classic Bengaluru January comfort.Humidity levels are near 47 percent.

These winds help the city feel breezy when individuals are out in open areas.Rain is essentially off the table for today. There is 0 mm of precipitation expected. The chance of rain is 0 percent.Visibility remains strong at approximately 10 kilometers. This is good news for commuters and anyone driving longer distances.Hourly shifts in weather will not be dramatic. The day is expected to follow a clear rhythm.Mornings start cool and pleasant. Midday turns warm under direct sun. Evenings ease back quickly.Therefore, if you are out after office hours, you will likely want a light layer.Astronomically, the day runs from sunrise at 6:46 AM to sunset at 6:15 PM.

Air Quality Update
A pollution recap indicates that yesterday was ‘moderate’, primarily led by fine particles.Tuesday, January 20, recorded an AQI (India) of 86, which is classified as Moderate. The AQI (US) was 127. Both readings indicate air that can be uncomfortable for sensitive individuals.The standout concern was particulate pollution. PM2.5 levels were at 49, and PM10 levels were at 62. Carbon Monoxide (CO) was measured at 335.In real-life terms, this typically translates to a slightly “dusty” feel, mild coughing for some, or itchy eyes—especially for people with asthma, allergies, or those spending long hours outdoors.Today’s weather conditions may offer some assistance. The sunshine and light-to-moderate winds can aid dispersion during the day.However, Bengaluru’s cooler mornings and calmer late evenings often allow pollutants to linger close to the ground.If you notice a bit of haze during your commute, that’s consistent with these conditions.
Recommendations
Planning the day does not require overthinking. For the weather, this is a sunglasses-and-water kind of afternoon, even in January.The sun will feel strong between late morning and mid-afternoon, so a cap helps if you’re walking or riding.Regarding air quality, if you are sensitive or simply stuck in long traffic corridors, consider a mask during peak commute hours.It is advised to try to schedule outdoor workouts for the early morning or post-sunset. When doing so, choose quieter parks or inner roads rather than main junctions.At home, keeping windows open in the breezier mid-day hours can help freshen indoor air. Conversely, closing them during heavy-traffic periods may reduce particulate entry.
The Week Ahead
The week ahead forecasts steady sunshine, slightly warmer days, and milder nights.The broader outlook remains stable and mostly sunny.From January 22 to January 25, high temperatures are expected to hover around 27 to 29 degrees Celsius. Nights during this period will range from 13.5 to 15.8 degrees Celsius.Sunday, January 25, looks like the warmest day at about 29.2 degrees Celsius. This is excellent for outdoor plans if you start early and avoid harsh midday sun.By January 26 and 27, nights are projected to turn noticeably milder, with temperatures rising from 16.9 degrees Celsius to 18.5 degrees Celsius. Humidity is also expected to increase, reaching 68 percent then 62 percent.A touch more cloud is anticipated on January 27, described as “partly cloudy.”Rain remains negligible overall, with a trace of 0.01 mm on January 26 and 0.1 mm on January 27.The slightly higher humidity can make evenings feel less crisp than earlier in the week.If you want the most “clean, crisp” outdoor window, January 22 or January 23 look particularly dependable: sunny, dry, and not too warm.Data referenced in this article is taken from AQI.in.
