According to the National Weather Forecasting Centre of the India Meteorological Department (IMD):

Wind Pattern and Ventilation Index Forecast

Air mass inflow forecast in Delhi along with predicted ventilation coefficient and weather forecast is as follows:

1. The air quality over Delhi-NCT is likely to remain in Poor category on 02.07.2021. PM10 will be the predominant pollutant owing to strong surface winds favourable for raising dust concentration locally and transport of dust from arid regions. The air quality is likely to deteriorate owing to strong winds/dust storms and reach in upper end of Poor category on 03.07.2021. The air quality is likely to improve marginally on 04.07.2021 but remain in Poor to Moderate category. The Outlook for subsequent 5 Days: The air quality is likely to remain largely in Moderate category.
2. The predominant surface wind is likely to be coming from West/Southwest directions of Delhi with wind speed 15-18 kmph, partly cloudy sky, heat wave conditions at isolated places, dust storm/thunderstorm accompanied with very light rain and gusty winds (speed 40-50 kmph on 02.07.2021. The predominant surface wind is likely to be coming from West directions of Delhi with wind speed 12-15 kmph, partly cloudy sky and possibility of very light rain/thundershowers on 03.07.2021. The predominant surface wind is likely to be coming from West directions of Delhi with wind speed 12-15 kmph, partly cloudy sky and possibility of thundery development on 04.07.2021.
3. Predicted maximum mixing depth is likely to be approx. 4300 m on 02.07.2021, 1300 m on 03.07.2021 and 3500 on 04.07.2021 over Delhi. Maximum Ventilation index is likely to be approx. 21000 m2/s on 02.07.2021, 14000 m2/s 03.07.2021 and 14500 m2/s 04.07.2021. The ventilation index lower than 6000 m2/s with average wind speed less than 10 kmph is unfavourable or dispersion of pollutant.
