June July 2024: District wise rainfall in India’s SW Monsoon

In the month of July 2024, the second month of India’s South West 2024 monsoon, India received 306.6 mm (318.4 in July 2023 [i] and 327.7 mm in July 2022 [ii]) rainfall, 9.3 % above (13.5% above normal in July 2023 and 16.8% above normal in July 2022) the normal July rainfall of 280.5 mm as per India Meteorological department. So this is the third consecutive year when rainfall in July is above normal. In July 2021, the rainfall was 266.1 mm [iii], about 6.7% below normal and in July 2020, the rainfall was 257.1 mm [iv], or about 9.9% below normal.

	Normal Rainfall, mm	Actual Rainfall, mm	% departure from normal
June 2024	165.3	147.2	-11
July 2024	280.5	306.6	+9.3
June-July 2024	445.8	453.8	+2

The total SW Monsoon 2024 rainfall till July 31, 2024, or June July 2024 rainfall was 453.8 mm, 2% above normal June July rainfall of 445.8 mm. The IMD describes the July 2024 and also the June July 2024 rainfall as normal rainfall just based on this overall national rainfall figure, that nomenclature is clearly oblivious of the spatial or temporal pattern of rainfall during the relevant months. The rainfall distribution has been far from normal in July 2024 or June July 2024.

Region wise rainfall IMD divides the country into four regions: NW India, E and NE India, Central India, South Peninsula. The IMD Bar charts for each of the regions and at national level for June July 2024 rainfall are given below.

State wise Rainfall As we can see from the IMD map above, out of 36 States and Union Territories (UTs), None had large Excess (Actual rainfall more than 60% above normal), Ten had Excess (Actual rainfall 20-59% above normal), sixteen had normal (Actual rainfall 19% below normal to above normal), Ten had deficit (Actual rainfall 20-59% below normal rainfall) and None had Large Deficit (Actual rainfall over 60% below normal) in rainfall in June July 2024. Goa had the highest rainfall of 2944.2 mm. Ladakh had the lowest rainfall of 15.1 mm. Tamil Nadu had the highest surplus % at 56% and Chandigarh had the highest deficit % at -56%.

Sub Division wise rainfall IMD divides India into 36 meteorological divisions (the logic of many of them is far from clear). In June July 2024, as we can see from the map above, No sub division had Large Excess rainfall, thirteen had Excess rainfall, fourteen had Normal rainfall and nine had deficit rainfall. Coastal Karnataka had the highest rainfall at 2555.7 mm and Punjab had the lowest at 119.1 mm rainfall in June July 2024.

River Basin wise Rainfall As we can see from the above map, IMD also reports river basin wise rainfall, but as we have been noting in the past, this reporting remains rather callous and inadequate, unfortunately. This is clear from the above map, where we can see that IMD map provides no data of rainfall in June July 2024 in large number of river basins. Not listing the names of the river basins on the map is another serious lacunae of this IMD map.
