Mumbai seems to be witnessing a see-saw phenomenon when it comes to the air quality. While Saturday and early Sunday saw the Air Quality Index (AQI) in the ‘moderate’ category, bringing in some relief after almost a week, the AQI again climbed to the ‘poor’ category by Sunday evening.
   
Experts have attributed this fluctuation in the air quality to the speed of winds blowing from the sea that eased the rising pollution levels.

The System of Air Quality Weather Forecasting And Research (SAFAR) on Saturday recorded an overall AQI of 152 (moderate) in the city, a drop from 200 to 250 recorded through the past week. Till Sunday afternoon, it remained at 159, but it shot up to 235 (poor) by evening. As per SAFAR’s forecast, AQI will hover around 200 to 218 on Monday.
