Mumbai is expected to experience another hot and humid day on Thursday, October 15, as the India Meteorological Department (IMD) continues its heat-related warnings for parts of Maharashtra. Temperatures in the city have remained significantly above seasonal averages, with residents likely to face uncomfortable conditions through the day.
The IMD has warned of hot and humid weather in isolated areas of Mumbai and neighbouring districts. Raigad and Ratnagiri are also facing heat-related warnings, while Thane and Palghar are expected to experience similar conditions. The prevailing weather pattern has kept daytime temperatures elevated across the Mumbai Metropolitan Region and parts of the Konkan belt.
Mumbai and its suburbs are likely to witness mainly clear skies on Thursday, with the maximum temperature forecast at around 38 degrees Celsius and the minimum at approximately 26 degrees Celsius.
The combination of high temperatures and humidity could make conditions particularly uncomfortable, especially during the afternoon. The IMD has also warned of the possibility of heatwave conditions in parts of the region.
Residents are advised to limit prolonged exposure to direct sunlight during the hottest hours, drink sufficient water and take precautions against heat-related illness.
According to the weather observations provided for Thursday morning, the Colaba observatory in South Mumbai recorded 36.4 degrees Celsius, while the Santacruz observatory in the western suburbs registered 37.8 degrees Celsius.
The readings indicate that temperatures remain elevated across both the island city and its suburbs. The Santacruz observatory has recorded temperatures above 37 degrees Celsius during the ongoing October heat spell, with previous reports also documenting unusually high daytime readings.
Despite the rising temperatures, Mumbai's overall Air Quality Index (AQI) was reported at 95 on Thursday morning, placing it in the satisfactory category, according to the figures supplied from the Central Pollution Control Board's SAMEER app.
However, air quality varied across monitoring stations. Deonar recorded the highest AQI among the listed Mumbai locations at 151, followed by Worli at 116 and Bandra-Kurla Complex at 114. Malad recorded 104, while Byculla and Borivali registered 88 each.
Ghatkopar reported the lowest reading at 59, followed by Kandivali at 77. These differences indicate that pollution levels were not uniform across the city.
Across the wider Mumbai Metropolitan Region, Thane recorded an AQI of 78, while Navi Mumbai registered 89 and Kalyan reported 86.
Although the reported regional readings remained within the satisfactory category, Deonar's reading of 151 falls in the moderate category under India's national AQI classification. Residents in areas with higher pollution levels may therefore need to take additional precautions, particularly if they are sensitive to air pollution.
With temperatures expected to remain high, residents should stay hydrated, wear lightweight clothing and avoid strenuous outdoor activities during peak afternoon heat. People who work outdoors, older adults and young children should take particular care.
