Bengaluru weather: Sunny skies, comfortable temperatures; AQI remains moderate

Bengaluru is set for a classic dry winter day on Thursday, January 22, 2026, featuring bright sun, clear skies, and comfortable temperatures, with an afternoon high of 26.9°C and an early-morning low around 14.1°C, alongside virtually no chance of rain; however, air quality remains a concern as yesterday’s AQI (India) was 106, a poor category day, which may persist today, particularly during peak traffic hours, prompting recommendations for masks for sensitive individuals on busy roads.

Bengaluru is experiencing a classic dry winter day on Thursday, January 22, 2026, characterized by bright sun, clear skies, and comfortable temperatures throughout most of the daylight hours. The afternoon high is expected to reach 26.9°C, while the early-morning and late-night low will be around 14.1°C. Rain is virtually absent from the forecast, with 0 mm precipitation and a 0% chance of rain indicated.

Sun-soaked day, cool start and a breezy afternoon

The day is described as sun-soaked, beginning with a cool start and transitioning into a breezy afternoon. Sunny conditions are anticipated from morning to evening, accompanied by dry air and good visibility. The temperature range is notable, with cool conditions at sunrise, warmth by midday, and a return to mild temperatures after sunset. The day's average temperature is projected to be near 20°C, and humidity is expected to hover around 44%, which is considered relatively comfortable for Bengaluru. Winds are forecast to increase slightly as the day progresses, reaching maximum speeds near 20.5 km/h, creating a light breeze in open areas and on elevated roads.
Hourly temperature shifts are not expected to be dramatic, but the usual Bengaluru rhythm will apply. The coolest period is in the early morning, suggesting the need for layers if one is out before office hours. The warmest and brightest stretch will occur from late morning to mid-afternoon, when the sun can feel sharp. A gentle cool-down will commence after sunset, which is scheduled for 6:16 PM. Clear skies mean that evenings may feel slightly cooler than anticipated upon exiting air-conditioned environments.

Yesterday’s air quality: “poor” and particle-heavy

Air quality presents a caveat for the day, as yesterday’s AQI (India) was recorded at 106, placing it in the poor category. This air quality level has the potential to persist into today, particularly during peak traffic hours. Wednesday, January 21, recorded an AQI (India) of 106, categorizing Bengaluru's air as poor. The US AQI equivalent for this period was 142, indicating unhealthy air for sensitive groups. A primary concern was particulate pollution, with PM2.5 levels at 58 and PM10 levels at 74. These levels are typically associated with irritation of the eyes and throat, triggering coughing, and aggravating asthma or sinus issues. Such effects are particularly noted for children, seniors, and individuals with respiratory conditions.
Today's sunny and dry weather conditions present a mixed impact on pollution levels. A light breeze can aid in dispersing surface pollutants. However, dry conditions combined with steady traffic can contribute to dust and fine particles remaining suspended, especially in congestion-heavy corridors and near construction zones. Individuals who experienced irritation yesterday are advised to take precautions again today.

What to wear, carry, and plan around (weather + AQI)

For most individuals, today is considered suitable for outdoor errands and commutes, provided timing is managed effectively. Mornings may feel crisp, making a light jacket appropriate for early outings. Sunglasses and sunscreen are recommended by midday when the sun's intensity is highest. Those sensitive to pollution may consider wearing a mask on busy roads. For outdoor exercise, it is suggested to choose greener, less traffic-dense areas, preferably earlier in the morning. Given yesterday’s particle load, a well-fitted mask is a sensible addition for those riding two-wheelers, encountering traffic, or walking along main roads. Staying hydrated is also advised, as dry air combined with pollution can lead to fatigue more quickly than expected.

The week ahead: steady warming, mostly sunny skies

The upcoming week for Bengaluru is projected to be consistently dry and bright. Days are expected to warm, and night-time temperatures are anticipated to rise slightly. Friday, January 23, is forecast to be sunny with temperatures of 27.5°C during the day and 13.8°C at night. Saturday, January 24, will see temperatures nudge warmer to 28.3°C during the day and 14.8°C at night, with only a trace of 0.02 mm precipitation indicated, signifying essentially dry conditions. Sunday, January 25, and Monday, January 26, are expected to be the warmest period, with highs reaching 28.8°C and 29.1°C, respectively. Nights during this stretch will also become milder, ranging from 16.4°C to 17.4°C. Tuesday, January 27, introduces the only notable alteration in the weather pattern, with partly cloudy skies. Despite the cloud cover, temperatures will remain high, at 28.9°C during the day and 17.4°C at night. Wednesday, January 28, will revert to sunny conditions, with temperatures peaking around 29.7°C. For outdoor activities, Saturday and Sunday are highlighted as excellent days, offering sunny, warm, and dry conditions. However, residents are advised to monitor dust and traffic-related pollution during this time. If air quality remains elevated, choosing parks over roadside walks and avoiding peak commuting hours when possible are recommended.
