Mumbai is expected to experience a partly cloudy sky on Sunday, with the India Meteorological Department (IMD) forecasting light to moderate rain accompanied by lightning and thunder across the city and its suburbs. Temperatures are likely to remain steady, with a maximum of around 33 degrees Celsius and a minimum of 27 degrees Celsius.
Despite the wet spell, air quality in the city continues to remain in the satisfactory range. According to the Central Pollution Control Board's Sameer app, Mumbai recorded an Air Quality Index (AQI) of 52, indicating minor breathing discomfort for sensitive individuals.
Air quality levels across key monitoring stations in the city stayed largely stable:
Bandra Kurla Complex: 44
Andheri East: 32
Borivali East: 51
Byculla: 58
Chembur: 56
Deonar: 70
Ghatkopar: 86
Kandivali West: 54
In the Mumbai Metropolitan Region (MMR), AQI readings also remained in the satisfactory category. Thane recorded an AQI of 57, Navi Mumbai stood at 60, while Kalyan registered 76.
Overall, while intermittent rain and thunderstorms are likely to influence weather conditions through the day, Mumbai's air quality continues to remain within acceptable limits across most parts of the region.
Mumbai's water supply situation remained under strain on Sunday, with the combined stock in seven key lakes supplying the city standing at 7.08 per cent, according to the Hydraulic Engineer's Department, Master Control Centre (Bhandup Complex).
The total usable water stock across the system was recorded at 1,02,460 million litres, while overall storage stood at 14,47,363 million litres.
The Upper Vaitarna lake remained critical, with its level at 594.96 metres, below the lower dead level (LDL). The lake recorded no usable live storage, with officials noting that it continues to operate under constrained conditions. Only 8 mm rainfall was recorded in the catchment area.
Modak Sagar stood at 148.06 metres, with 18.50 per cent usable content (23,853 ML). The lake received 69 mm rainfall.
Tansa lake recorded a level of 118.93 metres, with extremely low usable storage at 0.41 per cent (589 ML), despite 101 mm rainfall in its catchment.
Middle Vaitarna showed slight improvement, rising by 0.06 metres to reach 240.72 metres, with 11.36 per cent usable content (21,977 ML). The lake received 71 mm rainfall.
Officials also confirmed that the Middle Vaitarna WSCPO gate was opened on 23 June 2026 at 11 am, indicating controlled water release operations.
The city's largest contributor, Bhatsa dam, remained under pressure with only 5.85 per cent usable content (41,926 ML). The lake level stood at 108.17 metres, with 88 mm rainfall recorded.
Vehar and Tulsi show comparatively better levels
Smaller lakes showed relatively higher percentages:
Vehar lake: 77.04 metres, 44.83 per cent usable content (12,417 ML), rainfall 180 mm
Tulsi lake: 133.36 metres, 21.12 per cent usable content (1,699 ML), rainfall 311 mm
The combined storage of all lakes for 2026 stands significantly lower compared to previous years, with 38.58 per cent in 2025 and 5.35 per cent in 2024 recorded for comparison benchmarks.
Officials also noted that Upper Vaitarna water release began on 22 June 2026 at 11 am, and that rainfall in the Bhandup Complex area remained nil for the day, though cumulative rainfall stands at 195 mm.
With reservoir levels still uneven and key lakes like Upper Vaitarna under stress, the city's water supply situation continues to depend heavily on upcoming monsoon intensity and catchment inflows in the coming days.
