Mumbai: The city woke up to hazy skies and a layer of smog on Sunday, as air quality continued to worsen across several parts of the city. According to data recorded this morning, October 19, Mumbai’s
overall Air Quality Index (AQI) stood at 149, slipping further from Saturday’s reading of 136 and placing the city in the “moderately polluted” category.
The India Meteorological Department (IMD) reported hazy sunshine and warm temperatures, with the mercury hovering around 27°C in the morning and expected to rise to 33–34°C later in the day. Light to moderate rain may occur at isolated places across the Konkan-Goa coast, Madhya Maharashtra, and Marathwada, but Mumbai itself is likely to remain dry.

AQI Worsens As Diwali Celebrations Begin
Among all monitoring stations, Colaba emerged as the most polluted pocket with an AQI of 227, falling in the “poor” category, while Trombay followed at 163. Experts warn that as winter approaches and wind speeds reduce, pollutants tend to linger closer to the surface, pushing air quality levels further down.
For many Mumbaikars, the day began with irritation in the throat and eyes, a telltale sign of rising pollution. Health experts have advised residents to wear masks outdoors and avoid strenuous activities such as jogging or cycling during the morning and evening hours when smog tends to settle closer to the ground.
