Rise in temperature in Delhi indicator of withdrawal of Southwest Monsoon

After observing some good weather during the first two weeks of September, the maximum temperature has been rising in Delhi and making the daytime a little uneasy.  However, early morning and evening hours are pleasant and comfortable.This can easily be understood from the fact that the day temperatures are recording close to 36°C, which is about 2 degrees above normal but the minimums have been settling a degree below normal.

The maximum temperature recorded at the Safdarjung Observatory on Thursday was 35.7°C which is a degree above normal, while the minimum settled marginally below normal at 25.3°C. This is one of the features witnessed during the withdrawal of the Southwest Monsoon in Delhi. During this time the day temperatures rise and minimums observe a drop due to reversal of winds from southeasterly to northwesterly and absence of cloud cover. The humidity levels have also dropped in the city, which is another factor indicating towards the withdrawal.

Withdrawal of Southwest Monsoon in Delhi usually happens around the third week of September, getting delayed sometimes. In 2013 the withdrawal of Southwest Monsoon in Delhi happened by October 14.

Meanwhile, the withdrawal of monsoon has begun from west Rajasthan. It has also retreated from Kutch, parts of Punjab and Haryana. Gradually monsoon will retreat from Jammu and Kashmir, Himachal Pradesh, Uttarakhand, west Uttar Pradesh, east Rajasthan and Gujarat in next few days. The usual date of commencement of withdrawal of Southwest Monsoon is  1st of September.
