Chennai residents can expect a warm and partly cloudy day this Tuesday, January 13, 2026. The city's weather will feature comfortable temperatures but notable humidity and ongoing air quality concerns that require attention.
Tuesday's Detailed Weather Conditions
The maximum temperature is forecast to reach 28.2 degrees Celsius, while the minimum will dip to 22.8 degrees Celsius. This narrow range creates a steady, humid feel throughout the day, with average humidity around 70 percent.
While the air won't feel oppressively hot, it may become slightly sticky during late morning and afternoon hours. Skies will remain partly cloudy, offering some sunshine but also cloud cover.
Rain and Wind Expectations
Rainfall is essentially negligible for Tuesday, with just 0.01 mm of precipitation expected. The daily chance of rain stands at zero percent, meaning umbrellas won't be necessary.
Winds will be noticeable but not disruptive, with maximum speeds anticipated around 20.5 kilometers per hour. These breezes may offer some relief outdoors, particularly during warmer periods.
Daily Weather Rhythm and Air Quality
The day will follow Chennai's typical weather pattern, beginning with a milder start around sunrise at 6:35 AM. A warmer, brighter stretch will develop through midday, with temperatures gradually easing after sunset at 6:01 PM.
Evenings should feel comfortable for strolls, though humidity may persist. The moon will be in its Waning Crescent phase with 28 percent illumination, rising at 1:52 AM and setting at 1:30 PM.
Air Quality Concerns and Health Impacts
On Monday, January 12, Chennai recorded an AQI-IN of 89, placing air quality in the "Moderate" Category 2 range. This corresponds to an AQI-US of 136 on the American scale.
Particulate pollution remains the primary concern, with PM2.5 levels measured at 52 µg/m³ and PM10 at 65 µg/m³. Carbon Monoxide registered at 316.
Sensitive individuals may experience throat irritation, mild coughing, watery eyes, or a heavy-chest feeling, particularly children, older adults, and those with asthma. These effects can intensify with prolonged outdoor exposure.
Today's breezier conditions may help disperse pollutants somewhat, but without rain to wash particles from the air, quality may not improve dramatically. Peak traffic hours could see particularly noticeable pollution.
Health Recommendations and Activity Planning
With warm temperatures and visible sun through clouds, light cotton clothing is advisable. Sunscreen becomes important for those outdoors around midday, and keeping water readily available helps combat dehydration risks from humidity.
For individuals commuting by bicycle or spending time near busy junctions, a well-fitted mask can reduce irritation from particulate exposure.
The optimal windows for workouts are early morning after sunrise or post-sunset, when heat stress is lower. Those sensitive to pollution should consider sticking to parks away from major roads rather than using roadside running tracks.
Weekly Weather Outlook
Chennai's weather becomes more straightforward after Tuesday. From January 14 to 19, the forecast indicates predominantly sunny conditions with no meaningful rain anticipated.
High temperatures will remain steady, ranging from 28.5 to 29.2 degrees Celsius. Nights will gradually become more comfortable as low temperatures dip from 22.4 degrees Celsius midweek to approximately 20.8 to 21.4 degrees Celsius by January 17-19.
Sunday, January 18, appears particularly pleasant for outdoor activities, featuring a warm high of 29.2 degrees Celsius and cooler low of 20.9 degrees Celsius. Humidity will be slightly lower around the mid-60s, translating to better evening comfort.
For those planning longer outdoor activities, mid-morning to late afternoon will be bright and warm throughout the week. Schedule strenuous errands earlier in the day and save evenings for more relaxed plans.
