All India rainfall graph The bar chart below is for the daily National Rainfall figures from June 1 to Aug 31 2025.

State wise rainfall As can be seen from IMD rainfall map for June-Aug 2025, Two (Rajasthan and Ladakh) states and Union Territories (UTs) had large excess rainfall (above 60% surplus) in this period. Seven states and Union Territories (UTs) had Excess (rainfall 20-59% above normal) in this three month period. 22 states had normal rainfall with rainfall between 19% deficit and 19% surplus, while Four states (Bihar, Assam, Arunachal Pradesh and Meghalaya) had deficit rainfall with rainfall 20-59% below normal in these three months. Meghalaya had the highest deficit at 42%. Goa again had the highest rainfall at 2785 mm.

Sub-Division wise rainfall IMD rainfall map for sub-division wise rainfall, out of IMD’s 36 subdivisions, One (W Rajasthan) had Large Excess rainfall during June Aug 2025. Rajasthan also figured here in last two years. Ten subdivisions had Excess rainfall during June Aug 2025. 22 sub divisions had normal rain, while Three (Bihar, Arunachal Pradesh and Assam-Meghalaya) sub divisions had Deficit rainfall. The Highest deficit was 37% for Arunachal Pradesh. Highest surplus was 66% in W Rajasthan. The Highest rainfall was 3091.8 mm in Coastal Karnataka. Coastal Karnataka also had the highest rainfall in the same period last year. Lowest rainfall was 214.5 mm in Tamil Nadu, Puducherry and Karaikal.

River Basin wise rainfall IMD also provides river basin wise rainfall map. As can be seen from the map, IMD again reports no rainfall or no data in large area. This is clearly an impossibility. It is this kind of anomalies that raise questions about seriousness and accuracy of IMD’s river basin wise rainfall figures, which are actually most important for forecasting floods and reservoir inflows.

DISTRICT WISE STATE WISE RAINFALL IMD also provides a map with all the district boundaries and rainfall category as we can see above.
