Delhi has monsoon season rainfall of 640.4 mm, spread between 01st June and 30th September. The capital city has already crossed the mark, while more rains are likely till the monsoon withdraws from the region. The normal date of withdrawal from Delhi is 25th September. Last year, the monsoon had withdrawn a day ahead of its schedule, on 24th September 2025. And, this had marked the capital’s earliest exit since 2002. No reliable prediction of withdrawal can be made at this stage for the current season.

The monsoon trough remains the main trigger for rainfall around this time. The trough at the surface level has shifted far to the north of Delhi. The trough line passes through Jammu, Pathankot, Muzaffarnagar, Bareilly and Lucknow, and dips its eastern end into the Bay of Bengal. There is a low-pressure area now lying over Northeast Madhya Pradesh and adjoining Uttar Pradesh. It is likely to move west-northwestward for the next 24 hours and linger thereafter over that region. Under its influence, the trough will remain north of its normal position.

With the likely position of the trough, conditions are not favourable for any heavy rains for the city and suburbs in the remaining days of August. There are chances of fleeting showers, late in the afternoon or early evening today. However, the weather conditions will clear up quickly without causing any troubling activity. The chances of even passing showers will become minimal between Friday and Sunday. The day temperature will rise to reach about the 36°C (+/-1°C) mark over the weekend. The surface winds will pick up and become strong enough to suppress any sharp rise in mercury. The dry weather conditions will spill over to the start of next week as well.
