Mumbai swelters under hazy sky as Colaba hits 36.5 degrees C; city AQI at 89

Mumbai woke to a hazy sky and humid weather on Wednesday, November 4. According to the India Meteorological Department (IMD), generally cloudy skies are expected across the city. Mumbai has been going through hot and humid weather for some time, and Wednesday was no different. The forecast comes at a time when the city is already facing hot and humid conditions.

Daytime temperatures remained high. According to IMD data, the maximum temperature in Colaba was 36.5 degrees Celsius, while Santacruz recorded 35 degrees Celsius. The daytime temperatures at the city's two weather stations thus differed, with the mercury climbing higher in Colaba.

The IMD also recorded minimum temperatures for November 4, covering both the Colaba and Santacruz stations. The minimum was 26.6 degrees Celsius in Colaba and 23.9 degrees Celsius in Santacruz. There was no rain at either station during the period for which the readings were recorded.

On air quality, according to data provided for the Central Pollution Control Board's SAMEER app, Mumbai's overall Air Quality Index (AQI) on Wednesday morning was 89. Under the country's AQI categories, a reading between 51 and 100 is considered satisfactory, while a reading between 101 and 200 falls in the moderate category.

The city's overall AQI was in the satisfactory range, but pollution levels at some monitoring stations were in the moderate category. The AQI was 120 at Bandra-Kurla Complex and 119 at Worli. Among the other stations, Colaba recorded an AQI of 61 and Deonar 100. It was 99 in Andheri and 51 in Borivali. Air quality thus varied across different parts of the city.

Air quality was not uniform across the Mumbai Metropolitan Region (MMR) either. According to the data, Thane recorded an AQI of 68, while Navi Mumbai recorded 118, in the moderate category. Kalyan recorded an AQI of 84, which falls in the satisfactory range.
