Chennai Sees Mild Weather Yet Toxic Air
Chennai began Thursday with clear skies and a comfortable morning temperature of around 27°C, offering residents a brief respite from the week’s humidity. However, the city’s air quality continues to deteriorate, with pollution levels hovering in the ‘very poor’ bracket a reminder of the widening gap between favourable weather conditions and the city’s struggles with clean air.
According to real-time data sourced from AQI.in, Chennai recorded an AQI of 268 on Wednesday, driven primarily by high concentrations of PM2.5 and PM10. These levels remain significantly above the recommended safe limits and pose heightened risks for children, older adults and individuals with respiratory or cardiac conditions. While the return of sunny weather may help disperse some of the suspended particles, officials caution that pollution hotspots—particularly along traffic-heavy corridors—are likely to persist through the week.
A senior official involved in urban environmental monitoring noted that the combination of construction dust, vehicular emissions and changing wind patterns typically intensifies particulate matter during December. “Without sustained reductions in transport emissions and better controls on roadside dust, the temporary relief offered by clear skies will not translate into cleaner air,” the official said. Experts argue that Chennai’s long-term resilience will depend on adopting low-carbon mobility solutions and enhancing neighbourhood-level green buffers. Despite air quality concerns, today’s conditions are otherwise pleasant. Humidity levels are moderate at about 70%, and winds of nearly 25 km/h are expected to bring a mild cooling effect through the afternoon. The day’s temperature is forecast to remain stable, with a high close to 27.2°C and an evening low near 21°C. The chance of rainfall is minimal at 2%, suggesting that most outdoor activities are unlikely to be disrupted. Residents planning to step out are advised to use sunscreen and sunglasses, while health experts recommend masks during peak traffic hours.
The week ahead is expected to maintain a similar pattern—mostly sunny days with marginal temperature variations. Forecasts indicate patchy rain on 16 and 17 December, with an 84% likelihood of precipitation. Light showers could offer short-lived relief by settling dust particles, though meteorologists caution that humidity spikes may follow. Clear skies are expected to return by 18 December, making it the most favourable day for outdoor plans. For a fast-growing coastal city, the contrast between pleasant weather and persistent pollution highlights a broader challenge: ensuring that urban growth aligns with sustainable transport choices, better air monitoring and equitable public-health safeguards. As Chennai navigates fluctuating winter conditions, the focus increasingly shifts from enjoying a sunny day to building a cleaner, more breathable urban future.
