Delhi: Rainfall so far this monsoon season highest in 46 years

NEW DELHI: A highly unusual monsoon season this year has yielded 1,100 mm of rainfall in Delhi so far, the highest in 46 years, and almost double the precipitation recorded last year, the India Meteorological Department (IMD) said on Saturday. The figures are subject to change as more rainfall is predicted in the city during the day.

The Safdarjung Observatory, which is considered the official marker for the city, had gauged 1,150mm of rainfall in the 1975 monsoon season. This year, the precipitation has already hit the 1,100-mm mark and the season has not ended yet,” an IMD official said.

Normally, Delhi records 648.9mm of rainfall during the monsoon season, according to the IMD. Between June 1, when the monsoon season starts, and September 11, the city normally gets 590.2mm 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,” the official said. In 2003, the national capital had received 1,050mm of rainfall. Delhi gauged 636mm, 544mm, 876mm, 370.8mm and 505.5mm during the monsoon season in 2011, 2012, 2013, 2014 and 2015, respectively. It recorded 524.7 mm rainfall in 2016; 641.3mm in 2017; 762.6mm in 2018; 404.3mm in 2019 and 576.5mm in 2020, according to IMD data. It has been a bountiful September for Delhi, with 343.6mm 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 20.9mm precipitation in the month against the normal of 129.8mm. Delhi recorded more than 100mm of rainfall on two consecutive days at the start of the month — 112.1mm on September 1 and 117.7mm on September 2. On Saturday (September 11), it recorded 94.7mm 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.
