Bengaluru Weather: Sunny Skies, Warm Temps, But Beware of Lingering Air Pollution

Bengaluru is experiencing a bright and dry Monday, January 19, 2026, characterized by sunny skies, comfortable early hours, and a warm afternoon. The city is forecast to reach a high of 29.4°C and a low of 16.8°C, with no rain anticipated, making it a straightforward day for outdoor activities. However, the air quality, which was in the 'poor' bracket yesterday with an Indian AQI scale reading of 104, may persist today, particularly during peak traffic hours and in areas with low wind. This situation prompts a recommendation for sensitive individuals to consider carrying a mask for busier roads, while the week ahead is expected to maintain stable sunshine with slightly cooler nights.

The day begins with a classic mid-January feel, offering sunny conditions. The city is projected to see a high temperature of 29.4°C. A low temperature of 16.8°C is also anticipated. No rain is expected for the day, ensuring a clean outdoor-weather experience.

Air Quality Outlook

The air quality, however, may not be as clear as the skies appear. Yesterday's air quality registered in the 'poor' bracket on the Indian AQI scale. This reading was AQI-IN 104. This level of air quality has the potential to linger into today. This is especially true during peak traffic hours. It can also be noticeable in low-wind pockets across the city.

For those stepping out early, the morning remains pleasant for a walk. Individuals sensitive to dust and smoke may find it beneficial to carry a mask. This advice applies particularly when navigating busier roads.

Sunny conditions are expected to prevail throughout the day. A dry breeze is anticipated to provide significant comfort. Today’s forecast remains firmly in the dry zone. There is 0 mm of rain expected. The chance of rain is 0%. Strong visibility is also predicted, extending to approximately 10 km.

Temperatures will steadily increase from a cool start. Early morning temperatures are expected to be near 16–18°C. The afternoon will become warm and sunlit, reaching close to 29–30°C. The average humidity for the day is 40%. This level of humidity typically results in a less sticky day by Bengaluru standards. The feel is described as more "crisp-dry" than muggy.

Winds are projected to reach speeds of around 17.3 kmph. This wind speed is considered sufficient to maintain comfortable outdoor conditions. It is also expected to prevent the air from becoming completely stagnant. Hour-by-hour, this type of day generally feels best before late morning. It also feels best again after sunset. The midday-to-3 pm window is when the sun's intensity will be more noticeable. This is particularly true in open areas. After evening, temperatures are expected to decrease quickly. A light layer of clothing can be useful if one plans to be out late.

The sun timings for the day are as follows:
"Sunrise 6:46 AM and sunset 6:14 PM—a tidy reminder to plan outdoor workouts and errands before daylight fades."

Yesterday’s pollution levels were categorized as 'Poor' air. This was primarily led by PM2.5 particles. Bengaluru’s air quality on Sunday, January 18, registered an AQI-IN of 104. This falls into category 3, indicating 'Poor' air quality. The US AQI for the same day stood at 131. This is a level where sensitive groups can experience more noticeable impacts. The primary contributors to this pollution were fine particles. PM2.5 was measured at 54. PM10 was measured at 70. Carbon Monoxide (CO) was also noted at 372.

The implications of these pollution levels on the ground are significant. On days with poor air quality, individuals with asthma, allergies, or sinus sensitivity may experience certain symptoms. These can include throat irritation, watery eyes, or mild coughing. Quicker fatigue during outdoor exercise is also possible. These effects are particularly pronounced near traffic corridors and construction zones. Today’s sunny and dry weather conditions will not "wash out" pollutants. Rain might typically help in this regard. However, the moderate breeze could assist in dispersing pockets of pollution. This dispersion is expected to be more effective in the afternoon.

Daily Recommendations

Planning for Monday does not require overthinking. Sunglasses and sunscreen will be more beneficial today than an umbrella. For those who commute through busy junctions, such as Outer Ring Road stretches or central business districts, or near ongoing construction, a well-fitting mask should be considered during peak hours. This recommendation is based on yesterday’s particulate levels, which suggest that dust and exhaust may still be noticeable.

If exercising outdoors, it is advisable to aim for the early morning after sunrise. Alternatively, the later evening hours are also suitable. These times offer lower heat stress. Hydration is also an important consideration. Dry air combined with sun can lead to dehydration. This can happen even when the weather does not feel "hot-hot."

The Week Ahead

The week ahead for Bengaluru is expected to maintain a stable rhythm. Mostly sunny conditions are forecast. No rain is indicated for the upcoming days. High temperatures are anticipated to hover in the upper 27–30°C band. Nighttime temperatures will range from 15–18°C.

The specific forecast for the coming days is as follows:

• On January 20, the weather will be sunny, with a high of 29.7°C and a low of 17.9°C.
• On January 21, it will be sunny and slightly breezier, with temperatures reaching 28.9°C and dropping to 17.0°C.
• January 22 is expected to be sunny and a touch cooler at night, with a high of 28.7°C and a low of 16.2°C.
• January 23 will feature one of the cooler nights, with temperatures of 27.9°C during the day and 15.2°C at night.
• On January 24, sunny conditions will prevail, and humidity will rise, with a high of 28.0°C and a low of 15.2°C.
• January 25 will see partly cloudy skies and breezier conditions, with winds at 24.5 kmph, and temperatures of 28.2°C and 16.7°C.

For outdoor plans, Friday, January 23, appears particularly comfortable. This is due to its cooler low temperature of 15.2°C. It also features a manageable daytime high. A small caution is advised for Sunday, January 25. This applies to individuals sensitive to dust. Higher winds, reaching 24.5 kmph, can sometimes stir up road dust. This can occur even when skies are only partly cloudy.
