The Southwest monsoon has withdrawn from Delhi, yesterday, on 02 Oct 2024. The normal date of withdrawal is 25th September. Monsoon had commenced its withdrawal from West Rajasthan on the 23rd of September, after about one week delay. Delhi also had a similar extension. But, a variation of about 5-7 days is considered within normal.
Actually, Safdarjung, the base observatory at Delhi has not recorded any rainfall in the last two weeks. Conditions, as such, were favourable for the last few days. However, the withdrawal of monsoon is generally retrospective, as the withdrawal parameters need to adhere to certain standards, for 4-5 days. The withdrawal line has now extended far to the east of Delhi, simultaneously covering parts of West Uttar Pradesh and North Madhya Pradesh.
The day temperature rose to breach the 37°C mark, yesterday. Safdarjung recorded a maximum of 37.2°C, about 3°C above the normal. The capital city had earlier recorded monsoon season rainfall of 1029.9mm against the normal of 640.4mm, an excess of about a huge 61%. The average rainfall drops significantly in October to just 15mm and further plunges to a mere 6mm in November.
Monsoon may have withdrawn from Delhi but the city could have very light drizzle on the 04th and 05th of October, with more chances on the latter occasion. There is a dry cyclonic circulation over border areas of Punjab, North Rajasthan and the adjoining Pakistan region. A trough is extending eastward and running in close proximity to Delhi. The rising temperatures may act as a trigger to cause light rainfall. The showers, if at all, will be patchy and of short duration.
