The Southwest Monsoon has officially covered the entire country, advancing into the remaining parts of Rajasthan, West Uttar Pradesh, Haryana, and all of Delhi on June 29, the India Meteorological Department (IMD) confirmed on Sunday. This nationwide coverage has occurred nine days ahead of the usual timeline of July 8, marking the fastest all-India monsoon advance since 2020.The monsoon had a historic early start this year , arriving in Kerala on May 24, its earliest onset over the Indian mainland since 2009. Driven by strong low-pressure systems over the Arabian Sea and the Bay of Bengal, the rain-bearing system surged rapidly northward, reaching Mumbai by May 26 and covering most of central and northeastern India by May 29.This rapid progress, however, was followed by an unusual 18-day stagnation period until June 16, delaying its arrival in northwestern India. The anti-cyclonic winds over Delhi and adjoining areas further slowed the advance until this weekend.Residents of Delhi-NCR woke up on Sunday to cloudy skies and light rainfall, breaking a stretch of scorching heat. With the onset, moderate rain and thunderstorms are expected over the coming days, and IMD has issued a yellow alert for the region. The maximum temperature in the capital is likely to hover around 35°C, with intermittent showers and occasional heavy spells in the forecast.IMD’s June 29 update noted: “The Southwest Monsoon has further advanced into remaining parts of Rajasthan, West Uttar Pradesh and Haryana and entire Delhi today… thus, it has covered the entire country on June 29, 2025, against the normal date of July 8.”The early arrival is expected to positively impact agriculture and water reserves, particularly in northern states. The monsoon typically begins retreating from northwest India by mid-September and withdraws completely by mid-October.
