Northwest India has experienced an unusually wet August, with rainfall totals reaching levels not seen since 2001, according to the India Meteorological Department (IMD). The region recorded 265 mm of rainfall throughout the month, marking the highest August rainfall in 24 years and the 13th highest since 1901. This downpour contributed to an overall surplus in rainfall for Northwest India during the monsoon season.
The heavy rainfall in August led to severe flooding, particularly in Punjab, and extreme weather events throughout the Himalayan states. The IMD reported that the cumulative rainfall in Northwest India has surpassed normal levels by 27%. While Northwest India experienced excessive rainfall, other regions, including the northeast, Kerala, and Vidarbha in Maharashtra, faced deficient rainfall due to unusual weather patterns. The IMD noted that several districts in the Himalayan foothills and the northeast experienced below-normal rainfall because most low-pressure systems moved south of their usual position, and the monsoon trough also remained south of its typical position.
Across India, the average rainfall in August was 287.1 mm, a significant 16% increase above the normal of 248.1 mm. This figure marks the second-highest August rainfall for the country since 2001. Since the start of the monsoon season on June 1, India has received 749 mm of precipitation, compared to the normal 701 mm. South Peninsular India also experienced above-normal rainfall.
