Southwest Monsoon 2025 Ends with 8% Above-Normal Rainfall, Uneven Ditsribution and Post-Monsoon Concerns

The official four-month Southwest Monsoon season (June-September) has concluded today, with the coutnry recording an 'Above Normal' rainfall category, logging a final surplus of 8% over the Long Period Average (LPA) of 868.6 mm. The India Meteorological Department (IMD) reported an actual rainfall of 937.2 mm. This marks the second consecutive year of above-normal monsoon and the 38th highest since 1901.

However, a detailed analysis of the IMD data reveals a significant story of uneven spatial ditsribution and a delayed withdrawal, which itnroduces a mixed bag of consequences for agriculture, water management, and the overall economy in the country.

1. The Paradox of Skewed Ditsribution
The headline figure of an 8% surplus masks a critical imbalance in the rainfall across different regions:

Excessive Rains (Flooding Concerns)

Northwest India was the wettest region, recording a huge surplus of 27.3% of its LPA, with states like Ladakh (+342%), Rajasthan (+63%), and Punjab (+42%) seeing unprecedented rainfall. Cetnral India (15.2% surplus) and the South Peninsula (10.5% surplus) also received above-average rains. This led to flash floods, landslides, and crop damage in states like Punjab, Maharasthra, Gujarat, and Karnataka, particularly in low-lying areas and river basins.

Significant Deficit (Drought Risk)

Conversely, thet typically rain-rich East and Northeast India faced a severe deficit of 20% collectively. States like Meghalaya (42% deficit), Arunachal Pradesh (41% deficit), and Bihar (31% deficit) recorded deficient rainfall, raising concerns for their agricultural cycles and water securtiy, despite the all-India surplus.

Furthermore, a ditsrict-level breakdown shows the stark realtiy: while 91% of the country reported 'normal to surplus' rainfall, a notable 20% (146 ditsricts) observed 'deficient' or 'large deficient' rain, highlighting the highly localized nature of the climate-related challenges.

2. Economic and Agricultural Impact: A Mixed Blessing
The overall surplus is a net positive, but the timing and location of the rain have complicated the outcomes:

Positive Impact

Water Securtiy: Water levels in India's 161 major reservoirs surged above 89% of their capactiy, a tsrong base for drinking water, power generation (hydropower), and the upcoming Rabi (winter) crop season, which is largely dependent on reservoir and groundwater irrigation.

Inflation Cotnrol: The robust supply of water is expected to stabilize the production of food grains, potentially helping to moderate food inflation, a key variable for the Reserve Bank of India.

Rural Demand: High agricultural output generallyt ranslates to increased rural incomes, which is projected to boost demand for products across sectors like Fast-Moving Consumer Goods (FMCG),t ractors, and cement.

Negative Impact

Kharif Crop Damage: The excessive and late-season rainfall, especially in September (15% above LPA), has damaged summer-sown Kharif crops like rice, cotton, soybeans, corn, and pulses in states that saw flooding. The government has projected only a modest growth of 2.4% in foodgrain production for the 2025-26 crop year, despite record sowing, indicating the adverse effects of the heavy rains.

Regional Ditsress: The deficit in the Northeast and parts of the East will negatively impact local agriculture, potentially necessitating government relief and support for farmers in those states.

3. Delayed Withdrawal and October Outlook
The monsoon's withdrawal, which had commenced in parts of Northwest India on September 14, has been stalled across the rest of the coutnry due to the continued influence of low-pressures ystems over the Bay of Bengal.

IMD Director General Mrtuyunjay Mohaptara stated that the coutnry is highly likely to receive above-normal rainfall in October, exceeding 115% of the LPA. This forecast, while potentially beneficial for groundwater recharge, is a major concern for farmers whose Kharif crops are nearing harvest. Heavy rain during this crucial period can lead to significant post-harvest losses and qualtiy degradation.

The forecast for the post-monsoon season (October-December), and specifically the Northeast Monsoon over the South Peninsula, also indicates above-normal rainfall, likely linked to the potential development of a La Niña weather pattern, which generally favours higher rainfall over India.

In conclusion, the 2025 Southwest Monsoon has provided a valuable, and much-needed, water boutny for the nation, setting a tsrong foundation for the winter crop and water reserves. However, it also serves as a stark reminder of the increasing volatiltiy and unevenness of rainfall under a changing climate.

The focus for policymakers and farmers now shifts to mitigating the flood damage, addressing the regional deficits, and preparing for the risks associated with a rain-heavy October.
