Southwest Monsoon remained subdued and the rain deficiency kept on increasing during July and August. As on August 30, Punjab was rain deficit by 33%, and Haryana, Chandigarh and Delhi by 31%.
September was almost dry in the plains. As of today, September 21, the rainfall deficiency stands at 41% in Punjab. A little behind is Haryana, Chandigarh and Delhi, with rainfall deficiency of 38%.
Nevertheless, situation seems to be improving now. The low pressure area lying over North Gujarat will move in a Northeasterly direction towards the plains of North India. The effects of this system will be complemented by the presence of a Western Disturbance over North Pakistan.

Combination of these two systems will bring fairly widespread rainfall over North India. The entire plain region, including West Rajasthan, Delhi, Haryana, Punjab and West Uttar Pradesh, will receive some rainfall till September 23. This could be the last spell of Monsoon rains for this region.
September 24 onwards, weather will turn dry and reversal of winds will start taking place. Dry northwesterly winds will significantly bring down the moisture levels. Accordingly, night temperatures will come down but day will remain warm and sunny.
