The India Meteorological Department (IMD) has issued a yellow heat alert for Mumbai and Thane, warning of hot and humid conditions in isolated pockets on Sunday. The weather department has also placed Palghar, Raigad and Ratnagiri under a yellow alert as temperatures remain above normal across parts of Maharashtra.
Mumbai and its suburbs are likely to witness mainly clear skies, with maximum and minimum temperatures expected to hover around 36 degrees Celsius and 26 degrees Celsius, respectively. The IMD has warned of a possibility of heatwave conditions in the city and suburbs.
According to the IMD's 8:30 AM weather report, the Colaba observatory in South Mumbai recorded a high of 35.6 degrees Celsius, while the Santacruz observatory in the suburbs logged 37.4 degrees Celsius.
Mumbai recorded an Air Quality Index (AQI) of 101 on Sunday morning, falling in the moderate category, according to the Central Pollution Control Board's SAMEER app. Air quality in this category may cause minor breathing discomfort to sensitive people.
Among the city's monitoring stations, Bandra-Kurla Complex recorded the highest AQI at 424, followed by Deonar at 137 and Mazgaon at 115. Borivali recorded an AQI of 79, while Malad stood at 95. Ghatkopar recorded 67, Colaba 75 and Byculla 73.
Across the Mumbai Metropolitan Region (MMR), Thane recorded an AQI of 74, while Navi Mumbai stood at 80 and Kalyan at 82.
Meanwhile, 'stop work' and 'sealing' action will be taken against construction sites for violating air pollution norms, the Navi Mumbai Municipal Corporation (NMMC) warned on Saturday.
The warning came after NNMC chief Kailas Shinde held a high-level joint meeting with urban planners, executive engineers, architects, builders, and developers to ensure air quality does not deteriorate.
"Pollution severely impacts children, senior citizens, and respiratory patients in winter. Builders must treat environmental responsibility as a social duty rather than just as a business," Shinde said.
To combat dust and pollution, the civic body has enforced critical Standard Operating Procedures (SOPs), an official said.
It includes ban on use of drinking water for construction and dust suppression, with violators facing immediate site sealing.
"Sites must also install 30-foot-high barricades, fully wrap buildings in 'green-net', and set up 'tire-washing' facilities at exits to stop mud from reaching roads. Air quality sensors and public AQI display boards are mandatory at every construction site," the official said.
