The Southwest Monsoon officially withdrew from Delhi on Wednesday, marking its departure two days earlier than the usual September 25 withdrawal date. The India Meteorological Department (IMD) confirmed the shift, noting the monsoon’s retreat from significant portions of northwest India.
Information was available with The Chenab Times that the withdrawal on Wednesday extended to most parts of Punjab, Haryana, and Rajasthan, the entirety of the National Capital Territory, and select areas of Uttar Pradesh and Gujarat. The IMD’s normal withdrawal date for Delhi is based on data compiled between 1971 and 2019. In the preceding year, the monsoon had receded from the capital region on September 24.
The arrival of the Southwest Monsoon over Delhi this year occurred on July 2, a slight delay compared to its typical onset date of June 27. Despite the delayed onset, Delhi experienced rainfall that was 16 per cent above the normal average. Between June 1 and September 23, Safdarjung recorded 728.6 mm of rainfall, exceeding the expected 629.7 mm for the period. This overall rainfall accumulation was classified as falling within the ‘normal rainfall’ category.
Historical data from the IMD reveals notable variations in monsoon withdrawal dates. The earliest recorded withdrawal of the Southwest Monsoon from Delhi since 1961 took place on September 3 in 1982. Conversely, the most prolonged monsoon season, indicated by the latest withdrawal, was observed in 2013 when the monsoon did not depart until October 17. These historical figures underscore the dynamic nature of monsoon patterns across the region.
The IMD’s observations provide crucial insights into the seasonal weather patterns affecting northern India. The monsoon’s performance is a critical factor for the agricultural sector and water resources across the country. Early or delayed withdrawal can have significant implications for crop cycles and the replenishment of water reserves.
The withdrawal of the monsoon signals a transition towards drier conditions, with a gradual decrease in humidity and a rise in daytime temperatures expected in the coming weeks. The agency continues to monitor weather patterns across the subcontinent, issuing forecasts and advisories as necessary to inform the public and relevant authorities about impending weather events.
The data shared by the IMD is vital for agricultural planning, water management, and disaster preparedness. Understanding the nuances of monsoon onset and withdrawal helps various sectors to better anticipate and adapt to the seasonal climate shifts. The early withdrawal this year suggests a quicker transition into the post-monsoon season for Delhi and surrounding states.
