Year, Month and IMD Sub Division-wise (State) Actual Rainfall Data Since 1901
This Dataset contains year, month and India Meteorological Department (IMD) sub division wise actual rainfall data
Note:
`Normal Rainfall` is for the years 1971-2020. The India Meteorological Department (IMD) uses data from 1971-2020 to define the current normal rainfall for India, which is 868.6 mm annually and 868.6 mm for the southwest monsoon season. This updated Long Period Average (LPA) represents a 50-year average, replacing previous normals based on data from 1961-2010.
