Mumbai Weather Update: Temperature Drops to 15°C as Pollution Levels Raise Concern; AQI Stands at 144

Mumbai woke up on Thursday to a noticeably wintry morning, featuring clear skies, gentle winds, and a mild chill that offered a refreshing break from the city’s usual humid warmth. Despite the pleasant atmosphere, a faint layer of haze hovered over the skyline, highlighting Mumbai’s ongoing battle with worsening air quality. The India Meteorological Department (IMD) predicted a comfortable day with temperatures between 15°C and 32°C. However, the city’s air quality told a different story, with an early morning AQI of 144 as per AQI.in, placing Mumbai in the ‘poor’ category. Although slightly better than last month’s severe readings, the air remains unsafe for sensitive groups. Experts cite extensive construction work—ranging from metro corridors and bridges to coastal road stretches and private real estate projects—as the major contributors to rising dust and fine particulate pollution.
