Mumbai to see 37 C heat and humidity on Thursday; IMD issues yellow alert

Heat and humidity are expected to continue in Mumbai on Thursday, October 22. The temperature may reach about 37 degrees Celsius and air quality will remain in the moderate category. The India Meteorological Department (IMD) has issued a yellow alert for heat and humidity for some parts of Mumbai. The department has asked people to take precautions, as this spell of above-normal temperatures has been going on for long.

The sky over Mumbai and the suburbs will be mostly clear, with some clouds possible during the day. The maximum temperature is expected to be about 37 degrees Celsius, while the minimum will be in the mid-20s.

The combination of high temperature and humidity may cause discomfort, especially in the afternoon. People have been advised to drink plenty of water, wear light clothes and avoid strenuous outdoor activity during the hottest part of the day.

A yellow alert means hot and humid weather may prevail in some isolated areas. The IMD warning also covers the neighbouring districts of Thane and Palghar.

According to IMD data issued on October 21, the maximum temperature was 36.6 degrees Celsius in Colaba and 37.4 degrees Celsius in Santacruz. Both were above their respective seasonal averages.

The night was also warm. In the October 21 bulletin, the minimum temperature was 27 degrees Celsius in Colaba and 24.8 degrees Celsius in Santacruz.

On air quality, Mumbai's overall Air Quality Index (AQI) was 105 on Thursday morning. The figures are from the Central Pollution Control Board's SAMEER app. Under the national AQI classification, this places the city in the moderate category. Although the citywide figure was moderate, pollution levels differed across monitoring stations in different areas.

The highest AQI in the data was 153 at Bandra-Kurla Complex, followed by 142 at Worli and 134 at Colaba. The AQI was 123 in Andheri, 121 in Deonar and 105 in Borivali. This shows that people may face different levels of pollution depending on the area.

In the Mumbai Metropolitan Region, the AQI was 107 in Thane, 105 in Navi Mumbai and 96 in Kalyan. Under the national classification, a reading between 101 and 200 falls in the moderate category, while 51 to 100 is considered satisfactory.
