Sudden Downpour Disrupts Delhi, Brings Relief from Scorching Heat

On October 1, 2025, Delhi experienced a sudden and intense spell of heavy rain that caused significant disruptions across the city. The downpour led to the diversion of five flights to Jaipur between 12:15 and 12:30 pm due to adverse weather conditions at the Indira Gandhi International Airport. Traffic also slowed down considerably, and waterlogging was reported in several areas, including Zakhira Railway underpass, ITO, Vikas Marg, Minto Road underpass, and Mayur Vihar.

The heavy rain, however, brought a much-needed respite from the sweltering heat that had gripped the city in recent days. The maximum temperature on October 1 settled at 34.2°C, three degrees below the previous day's figure, while the minimum temperature was 28.7°C, five degrees below normal. Overall, Delhi recorded the second lowest monthly average minimum temperature (24.6°C) in September 2025 since 2018.
