As Monsoon is about to make a withdrawal from Delhi very soon, rains have already become scarce over the region. The city is recording peaking temperatures since the last few days. Moreover, Safdarjung observatory recorded 37.5°C in the last 24 hours, which is the second-highest temperature recorded in the city since the last 10 years. We can expect similar temperatures to prevail over the city today as well.
Normal Monsoon withdrawal date for Delhi is September 15 to 20. Mostly the withdrawal postpones over the city but is rarely preponed. However, looking at the rainfall pattern this time the withdrawal might come early.
Looking at the weather forecast for Delhi for the next ten days, rains will remain mainly light over the region. Downpour will be patchy and short spelled. One or two moderate spells cannot be ruled out.
The humidity usually rises in the first half of September while the temperatures keep low. Whereas as soon as the second half of September sets in, humidity starts to decrease, while temperatures start rising in the absence of overcast sky. Rains are lesser and fewer clouds are seen.
Monsoon withdrawal is a very gradual process, considering only a few days are left until Monsoon bids farewell to the city. Monsoons end on a rather silent note. Usually, the pattern of figuring Monsoon withdrawal is five days of no rain combined with less cloud cover, change in wind pattern, fall in humidity as well as a rise in temperatures.
If we summarize this Monsoon over Delhi, this season has been a subdued one with a rather late and a mild start. Moreover, rains continued to be deficient in all the three Monsoon months.
