Delhi has witnessed its earliest withdrawal since 2002, when the monsoon exited the capital city on 20th September. The earliest retreat of the monsoon from Delhi since 1961 was on 3rd September 1982. The most delayed withdrawal was on 17th October 2013, because of Cyclone Phailin striking the east coast.

Delhi received 728.6 mm of rainfall during the monsoon against the seasonal average of 629.7 mm. Last year, the monsoon rainfall was 902.6 mm, 41% more than normal. This year, the excess rainfall remained confined to 16% of the long-period average. Some more showers are likely during the remaining days of the month.

The remnant of the storm from the Bay of Bengal is likely to move over the central parts as a depression. A western disturbance is expected to move as an upper-air system across the Nepal region. The juxtaposition of these two systems will trigger a trough in close proximity to Delhi.

Under their combined influence, rain and thundershowers are likely over Delhi/NCR between 26th and 30th September 2026. The chances are lower on 26th and 30th September, while the probability is higher on 28th and 29th September 2026. Showers after the retreat of the monsoon are not very uncommon.

The reversal of the wind pattern and chances of sporadic rainfall will lower the day temperatures. However, an increase in humidity levels may lead to sultry weather over the weekend during the afternoon hours.
