New Delhi, Aug. 31 -- Delhi benefited from heavy rainfall this August due to a favourable weather system, even as the surrounding regions experienced a deficit, according to experts. The capital recorded 354.1 mm of rainfall between August 1 and August 30 (until 5:30pm). This is over 100 mm higher than the India Meteorological Department's (IMD) long-period average of 233.1 mm for the same period. The city last saw excess August rainfall in 2025 and 2024, when it recorded 400.81mm and 390.3mm rainfall, respectively - crossing the LPA for the first time since 2020, when rainfall was 237 mm. Since 2011, the city has crossed the threshold only six times: in 2026, 2025, 2024, 2020, 2013, and 2012. According to weather experts, this year's excess rainfall was due to the monsoon axis - the low air pressure that determines where it rains during the monsoon - which stayed over the city more than usual. "Rain depends on the weather systems formed over a region; however, this time the excess rain was primarily due to the surges of the monsoon axis. This year, despite the Haryana-Punjab-Rajasthan region seeing a rainfall deficit, Delhi saw excess rainfall because the monsoon axis stayed over Delhi-NCR and western Uttar Pradesh for longer than usual," stated amateur meteorologist, Navdeep Dahiya. According to the IMD forecast, Delhi is likely to see a rainy start to September, with very light to light rain across the city on Tuesday, and multiple spells of light to moderate rain on Wednesday. For Thursday and Friday, IMD has forecast very light to light rain. "The upcoming two to three days are likely to be dry. From September 2, we see the monsoon trough moving towards us again," said Dahiya....
