Record Rainfall Hits Northwest India, More Expected in September: IMD

Northwest India experienced unprecedented rainfall in August 2025, marking the highest levels for the month since 2001, according to the India Meteorological Department (IMD). The region, encompassing states like Uttarakhand, Uttar Pradesh, Punjab, Haryana, Jammu and Kashmir, Rajasthan, and Delhi, recorded 265 mm of rain, a 34.5% surplus compared to the normal 197.1 mm. This deluge contributed to a cumulative monsoon rainfall of 614.2 mm from June 1 to August 31, about 27% above the typical 484.9 mm, making it the wettest monsoon season in over two decades for the region.

The heavy rainfall triggered severe flooding and landslides, particularly in Punjab, where swollen rivers and breached canals inundated vast farmlands and displaced numerous residents. Himalayan states like Himachal Pradesh and Uttarakhand faced significant disruptions, with washed-out bridges and roads, while Jammu and Kashmir reported multiple cloudbursts. The IMD attributed the excess rainfall to active monsoon conditions amplified by frequent western disturbances.

South Peninsular India also saw substantial rainfall, logging 250.6 mm in August, 31% above normal and the third-highest since 2001. Cumulatively, the region received 607.7 mm from June to August, a 9.3% surplus. Nationally, August rainfall reached 268.1 mm, 5% above average, with the three-month monsoon total at 743.1 mm, 6% above normal.

Looking ahead, the IMD forecasts above-normal rainfall for September, predicting over 109% of the long-period average of 167.9 mm. This is driven by the expected onset of La Niña conditions, which could intensify cyclonic activity in the Bay of Bengal, particularly affecting northern states like Uttarakhand, Rajasthan, and Delhi. The IMD warns of potential landslides and flash floods in these areas. Monsoon withdrawal, typically starting in mid-September, may be delayed due to the anticipated heavy rainfall, according to IMD Director General Mrutyunjay Mohapatra.
