During the winter, the period from November 2022 to March first week this year was probably the worst air quality in the last five years for Mumbai, along with the AQI being higher than Delhi's on most days.
Showers, high speed of the winds have resulted in clean and fresh air
According to the System of Air Quality and Weather Forecasting And Research (SAFAR), the widespread showers and a high speed of the winds have resulted in clean and fresh air compared to the previous four months. The AQI of Mumbai on Sunday was 93, putting it in the ‘satisfactory’ category.
An AQI between 0 and 50 is ‘good’, 51-100 is ‘satisfactory’, 101-200 is considered 'moderate', 201-300 'poor', 301- 400 'very poor' and 401-500 'severe'.

Vehicular emissions, widespread construction projects
The main contributors of air pollution in the city have been vehicular emissions and widespread construction projects throughout the city. “The unseasonal rains have cleared the skies temporarily by natural means but the main concern still remains the deteriorating air quality during no rainfall days,” said a SAFAR official.
Meanwhile, the IMD has indicated clear skies on Monday, however, there is a possibility of cloudy skies with the likely light rainfall on Tuesday and Wednesday. The unseasonal rainfall experienced by the city so far has been the result of the interactions of the westerly and easterly winds.
On Sunday, Santacruz witnessed a minimum temperature of 25.8 degrees Celsius and a maximum of 34.1 degrees Celsius, with 73% relative humidity. Colaba experienced a minimum temperature of 26.0 degrees Celsius and a maximum of 32.2 degrees Celsius, with 82% relative humidity.
