Breaking previous year’s record rainfall in Delhi, 2021 has already hit the 1,100-mm mark and the season has not ended yet. The highly unusual monsoon season this year has broken all records, registering highest in 46 years. The Safdarjung Observatory, which is considered the official marker for the city, had gauged 1,150 mm of rainfall in the 1975 monsoon season, an IMD official said. Normally, Delhi records 648.9 mm of rainfall during the monsoon season, according to the IMD.

Heavy rains, which lashed Delhi and the National Capital Region (NCR) from Saturday early morning, submerged parts of Indira Gandhi International Airport and water-logged several areas that led to traffic jams. The India Meteorological Department (IMD) said today that the season has yielded 1,100 mm of rainfall in Delhi so far, and almost double the precipitation recorded last year.

Before 2021, Delhi saw extremely heavy rainfall in 1975 when a total of 1,150 mm of rainfall was recorded. The Indian Meteorological Department (IMD) had issued an orange alert, predicting moderate to heavy rainfall and thundershowers with gusty wind over Delhi NCR between 7 am and 10 am on Saturday.

Between June 1, when the monsoon season starts, and September 11, the city normally gets 590.2 mm of rainfall. The monsoon withdraws from Delhi by September 25.

“Light to moderate rain is likely in the next two days. Another wet spell is predicted around September 17-18,” informed the official. In 2003, the national capital had received 1,050 mm of rainfall.

Delhi gauged 636 mm, 544 mm, 876 mm, 370.8 mm and 505.5 mm during the monsoon season in 2011, 2012, 2013, 2014 and 2015, respectively. It recorded 524.7 mm rainfall in 2016; 641.3 mm in 2017; 762.6 mm in 2018; 404.3 mm in 2019 and 576.5 mm in 2020, according to IMD data.

It has been a bountiful September for Delhi, with 343.6 mm of rainfall recorded so far this month, which is the highest in at least 12 years, according to data available on the IMD’s website. The September rainfall this year has been in marked contrast to the last year, when the city got a meagre 20.9 mm precipitation in the month against the normal of 129.8 mm.

Delhi recorded more than 100 mm of rainfall on two consecutive days at the start of the month — 112.1 mm on September 1 and 117.7 mm on September 2. On Saturday (September 11), it recorded 94.7 mm precipitation. Despite the monsoon embracing Delhi only on July 13, making it the most-delayed in 19 years, the capital had recorded 16 rainy days in the month, the maximum in the last four years.

The string of rainy days gave 507.1 mm rainfall in Delhi, which was nearly 141 percent above the long-period average of 210.6 mm. It was also the maximum rainfall in the month since July 2003, and the second highest ever. The city recorded just 10 rainy days in August, the lowest in seven years, and a cumulative rainfall of 214.5 mm, lower than the average of 247 mm.
