Mumbai is expected to remain hot and humid on Saturday, October 17, with the India Meteorological Department issuing a yellow alert for hot and humid conditions in isolated parts of the city as temperatures approach 37 degrees Celsius.
The alert comes during an extended spell of above-normal October temperatures across Mumbai and nearby areas. The city and its suburbs are likely to experience mainly clear skies with some cloud cover during the day. The minimum temperature is expected to remain in the mid-20s.
The combination of high daytime temperatures and humidity could make outdoor conditions uncomfortable, particularly during the afternoon. Residents have been advised to stay hydrated, wear lightweight clothing and avoid strenuous outdoor activity during the hottest part of the day.
The IMD’s weather bulletin dated October 17 recorded a minimum temperature of 26.5 degrees Celsius at Colaba, 1.1 degrees above normal. Santacruz recorded a minimum of 26 degrees Celsius, which was marginally above its normal level. Neither observatory recorded rainfall during the reported period.
The minimum readings are separate from daytime maximum temperatures, which are generally recorded later in the day. The forecast maximum of around 37 degrees Celsius therefore indicates that afternoon conditions may be considerably warmer than the morning observations.
The weather warning extends beyond Mumbai, with the IMD issuing warnings for parts of the Konkan region. Conditions are expected to vary between districts, making local weather updates important for residents travelling across the Mumbai Metropolitan Region.
Heat conditions are also coinciding with uneven air quality across Mumbai. The city’s overall Air Quality Index stood at 112 on the Central Pollution Control Board’s dashboard on Saturday morning, placing it in the moderate category.
Readings were higher at several monitoring stations. Bandra-Kurla Complex recorded an AQI of 150, followed by Colaba at 144 and Deonar at 131. These station-level figures were also in the moderate category and indicate that pollution levels differed across neighbourhoods despite the citywide average.
Air quality across the wider Mumbai Metropolitan Region was similarly uneven, with some locations recording satisfactory levels while other monitoring stations reported moderate pollution. The variation means that people sensitive to pollution may need to check conditions in their immediate area rather than rely only on the overall city average.
With hot and humid weather continuing alongside elevated pollution in some neighbourhoods, residents have been advised to limit prolonged exposure to direct sunlight and take precautions during outdoor activity. The IMD alert and local air-quality readings remain the key indicators for conditions through Saturday.
