Delhiites encountered yet another day of dusty skies and muddy weather today. This grim weather has been prevalent over Delhi and NCR for the last four to five days. However, the situation has improved, and the sky conditions and visibility levels are better than yesterday and day before.
Although the air quality over some pockets of Delhi and NCR are still severe with the Air Quality Levels (AQI) of PM10 settling more than 500 μg/m3.
Given below table chalks out the AQI levels recorded at some of the locations of Delhi and NCR as on 3 pm:

As per the table above, the air quality index is at hazardous levels in Delhi University and Pitampura while, is comparatively better in Gurugram.
However, as per Skymet Weather, this layer of dust and sand is not a very unusual phenomenon and it usually happens during the pre-Monsoon season though it is the intensity, spread and duration of the dusty weather that varies.
At present, the situation is deteriorating over parts of Northwest India while Delhi is just on the fringes of this type of weather conditions.
The reason for the sandy skies over the national capital and its adjoining boundaries can be attributed to the dust an sand particles being transported from the hotter regions of Rajasthan and Pakistan. As these regions are dry, the sand is loose in nature and due to the strong wind flow, is able to get transported easily over Delhi and NCR.
However, Delhiites can now expect some relief from the ongoing dusty weather in the next 24 hours. As per Skymet Weather, the Western Disturbance as a cyclonic circulation lies over Jammu and Kashmir. In addition to this, a trough is also extending from the northern parts of Punjab to foothills of Uttar Pradesh, therefore, scattered rains are expected over the northwest plains and at one or two places over Delhi and NCR on June 16 and 17.
But the intensity of rain would be light and of short duration and the sky may become partly cloudy to cloudy for short duration. This would help in dropping the temperatures by two to three degree Celsius. However, these rains would for sure bring in the much-needed respite from the ongoing dusty weather.
The wind direction is also expected to change in subsequent 48 hours and by June 18 or 19, we expect, the strong winds which are blowing from the southwest to slow down and change their direction from southwesterly to become southeasterly and southerly.
Henceforth, the weather is likely to become dry by June 18 and 19 and humidity levels would also increase.
The month of June is the last pre-Monsoon month for the city and Monsoon usually makes an onset over Delhi and NCR during the fag end of the month, around June 29. The average monthly rains for Delhi stands at 82 mm and till date, Delhi’s Palam Observatory has recorded 27 mm of rains, meanwhile, 5 mm of rains were recorded by Safdarjung Observatory.
