Several parts of Mumbai received moderate to heavy rainfall accompanied by thunder during the early hours of Monday. Mumbai and its suburbs recorded intense showers in just one hour, civic officials said.
Rains lashed parts of the city for the second consecutive day, bringing much-needed relief from the heat and humidity. Overcast skies and a cool breeze made the morning pleasant across the metropolis.
Despite the rainfall, the southwest monsoon has yet to officially arrive in Mumbai. The India Meteorological Department (IMD) has indicated that the monsoon is likely to make its onset over the city by June 23.
According to rainfall data, several locations recorded moderate showers between 6 am and 7 am on Sunday. Worli received 25 mm of rainfall, followed by Ghatkopar with 24 mm, Lower Parel with 21 mm, Chembur with 20 mm and Mankhurd with 16 mm.
Apart from Mumbai, Savitribai Phule BMC School at Worli Naka recorded the highest rainfall at 61 mm, followed by G/S Ward with 58 mm. Other locations reporting significant rainfall included Aadarsh Nagar School, Worli and Malabar Hill, both with 44 mm, Worli Fire Station with 42 mm, F/S Ward with 41 mm, Worli Sea Face with 37 mm, and D Ward Office with 30 mm.
In the western suburbs, Pali Chimbai School, Bandra, and Supari Tank BMC School, Bandra, emerged as the wettest locations, each recording 70 mm of rainfall in just one hour. The H/West Ward Office registered 30 mm, while Bandra Fire Station received 28 mm. Rain gauges at Banana Leaf and Juhu Dispensary recorded 25 mm each.
While weather conditions remained humid, Mumbai's air quality continued to stay within the "good" category on Sunday.
According to data from the Central Pollution Control Board's (CPCB) SAMEER application, the city's overall Air Quality Index (AQI) was recorded at 50. An AQI between 51 and 100 falls under the satisfactory category, indicating that air quality is generally acceptable and poses minimal health concerns for most residents.
AQI readings across Mumbai's monitoring stations remained largely stable. Bandra Kurla Complex recorded an AQI of 35, Malad reported 87, Byculla registered 44, and Colaba recorded 58. Navi Mumbai and Thane also remained within the satisfactory category with AQI readings of 39 and 50, respectively.
Among the cleaner locations, Malad recorded an AQI of 40, placing it in the "Good" category. Mulund reported an AQI of 19, while Chembur recorded 33, both indicating relatively cleaner air.
The latest data suggests that air quality has remained stable across the wider Mumbai Metropolitan Region (MMR). Environmental experts attribute the favourable conditions to periodic rainfall activity and weather patterns that help disperse airborne pollutants.
With light rain likely, warm temperatures and high humidity expected to continue, Mumbai residents can anticipate typical monsoon conditions over the coming days, while air quality is expected to remain within acceptable levels.
