Chennai residents can look forward to a bright and straightforward Tuesday on January 27, 2026, with a clear forecast dominating the skies. The day promises to be rain-free, offering ideal conditions for outdoor activities, though air quality continues to warrant attention following recent moderate pollution readings.
Today's Weather Overview
The meteorological outlook for Chennai indicates a sunny day with absolutely no precipitation expected. Temperatures are forecast to climb to around 28°C, creating a warm afternoon, while morning and evening hours should remain relatively comfortable. However, the air quality situation requires vigilance from citizens, especially those with respiratory concerns.
Air Quality Analysis and Yesterday's Report
Yesterday's pollution levels fell within the moderate band, with an AQI (India) reading of 65, categorizing it as Category 2 (Moderate). The corresponding AQI (US) measurement stood at 110, indicating air that was neither bad nor ideal. Key pollutants included PM2.5 at 39, PM10 at 48, and Carbon Monoxide at 358.
For most healthy adults, these levels might cause minor throat or eye irritation during prolonged outdoor exposure or traffic encounters. Children, seniors, and individuals with asthma or sinus issues could experience heavier breathing during commutes or physical activities.
Today's sunny and breezy conditions may help disperse pollutants somewhat, but the absence of rain means there will be no natural cleansing of particles. Consequently, air quality improvements are likely to be modest unless traffic emissions remain minimal.
Detailed Daily Conditions
The temperature range for Tuesday is projected between 22.8°C and 28.1°C, with an average near 25°C. Humidity levels are forecast at approximately 67%, which, while not creating extreme stickiness, may result in mild clamminess as the sun rises higher.
Winds are expected to be moderately active, peaking around 22 kmph, helping to prevent heat stagnation, particularly in open and coastal areas. Visibility remains strong at 10 km, and the chance of rain is firmly at 0%, with no precipitation anticipated.
Residents can expect a cooler start after sunrise at 06:36 AM, with heat intensifying from late morning through mid-afternoon. Temperatures will gradually ease after sunset at 06:08 PM, though humidity may linger into the evening.
Recommendations for the Day
Given the forecast, here are some practical suggestions:
- Carry sunglasses to manage afternoon glare
- Keep water handy, especially if outdoors between late morning and 4 PM
- Opt for light cotton clothing as the most suitable attire
- Consider wearing masks in traffic-heavy zones like busy junctions, flyovers, and bus stands
- Schedule exercise for early morning when temperatures are milder
- Choose parks or quieter streets for workouts, avoiding roadside runs due to air quality concerns
Weekly Outlook
Chennai's weather is expected to remain consistently sun-dominant and stable through the upcoming week. From January 28 to 31, high temperatures will hover around 28–29°C, with lows gradually dipping from 22°C to 21.1°C, ensuring pleasant nights and early mornings.
Winds will stay in the moderate range of 16–21 kmph, with no rain anticipated. February 1 will continue with sunny conditions and a high near 28.1°C, while February 2 may see a shift to partly cloudy skies with slightly higher humidity, temperatures ranging from 22°C to 28.4°C.
For outdoor planners, Saturday, January 31, appears particularly comfortable—warm but steady with a manageable breeze and no rain risk. Those sensitive to air quality should note the lack of rain throughout the week and consider greener routes while avoiding long idling commutes.
Air Quality Trend Note
Yesterday's moderate AQI of 65 represents an improvement from earlier in the week when pollution levels spiked into poorer categories. While the trend shows positive movement, it's important to recognize that air quality has not yet reached clean levels, requiring continued awareness and precautionary measures.
