India Records Fourth-Lowest Southwest Monsoon Rainfall Since 2001, Receives 87.4% of LPA
India’s southwest monsoon season has ended on a significantly deficient note, with the country receiving 87.4% of its Long Period Average (LPA) rainfall during June–September 2026, according to the India Meteorological Department (IMD). This makes 2026 the fourth-lowest monsoon rainfall year recorded since 2001.
Rainfall Deficit Stands at 13%
The 87.4% figure translates into an overall 13% rainfall deficit compared with the long-term average. IMD classifies seasonal rainfall that is 10% or more below the LPA as “deficient.”
The season had appeared headed for an even larger shortfall, but heavy rainfall toward the end of September helped narrow the deficit. A late-season weather system brought widespread rain across parts of central, northern, eastern and northeastern India.
Possible Impact on Agriculture and Water Resources
The deficient monsoon could have implications for agriculture, water availability and the upcoming Rabi cropping season. The Centre has already discussed contingency measures, including crop monitoring, water budgeting and greater focus on less water-intensive crops.
IMD’s April long-range forecast had projected 2026 monsoon rainfall at around 92% of LPA, with a model error of ±5%.
