In a significant update, the India Meteorological Department (IMD) has forecast an above-normal monsoon for 2025. This early estimate suggests that the monsoon rainfall for the period June to September will be approximately 105% of the long period average (LPA). The LPA for the monsoon season is defined as the average rainfall over a 50-year period, and for India as a whole, this comes to 87 cm.

The forecast comes with a model error of +/-5%, which means that the actual rainfall could vary slightly from the predicted 105% of the LPA. This prediction indicates that India will receive a healthy monsoon, which is expected to provide adequate rainfall to meet the agricultural and water requirements across the country.

Monsoon Rainfall Distribution
According to the IMD, the monsoon rainfall for 2025 will be largely normal to above normal across most parts of the country. Specifically, the monsoon rainfall is expected to fall in the range of 96-105% of the LPA, which is considered a normal monsoon in India. A normal monsoon is critical for ensuring good agricultural yields, especially for key crops like rice, wheat, and pulses, which rely heavily on the summer rains.

The IMD’s forecast comes as a relief to farmers and stakeholders in the agriculture sector, as a normal to above-normal monsoon is expected to contribute positively to crop production and food security across the nation. In particular, regions that depend on rain-fed agriculture will be looking forward to consistent rainfall, which can mitigate drought risks and improve water storage levels in dams and reservoirs.

El Nino-Southern Oscillation (ENSO) Conditions
M. Mohapatra, the Deputy General Manager (DGM) of the IMD, clarified that the forecast for 2025 indicates that neutral El Nino-Southern Oscillation (ENSO) conditions are likely to prevail during the monsoon season. This is important because El Nino, a phenomenon characterized by the warming of ocean waters in the Pacific Ocean, has often been associated with below-normal monsoons in India. On the other hand, La Nina conditions, which refer to the cooling of ocean waters in the Pacific, have typically resulted in stronger than average monsoons.

However, with neutral ENSO conditions, it is expected that neither El Nino nor La Nina will have a dominant effect on the monsoon season, creating favorable conditions for a more balanced rainfall distribution across the country. This further supports the IMD’s optimistic forecast of an above-normal monsoon.

Why is the Forecast Significant?
A favorable monsoon season is of great importance for India's agricultural economy, as the country heavily depends on monsoon rains to irrigate crops. A deficit or excess in rainfall can lead to a variety of economic and social issues, including poor crop yields, rising food prices, and water scarcity. With 2025’s forecast signaling a positive monsoon, it could ease some of the concerns surrounding agricultural output and help stabilize the economy, particularly in rural areas that are dependent on agriculture.

Climate Models and Forecast Accuracy
The IMD's forecast comes from advanced climate models that analyze oceanic and atmospheric data. While these models have proven reliable in the past, it is important to note that forecasting the exact rainfall distribution and its timing remains challenging. Factors such as local weather patterns, temperature anomalies, and other atmospheric influences can cause variations in the final outcome.

The IMD’s prediction for the 2025 monsoon highlights its commitment to providing early warnings and proactive support to policymakers and the agricultural community, giving them time to plan and prepare for the season ahead.

Conclusion
The IMD’s forecast for an above-normal monsoon in 2025 is a significant update for India, as it points to a healthy rainfall season that could benefit both the agricultural and economic sectors. With neutral ENSO conditions expected to prevail, the monsoon is likely to be more predictable, and this will provide much-needed stability for crops and water resources across the country.

Farmers, policymakers, and stakeholders in agriculture are encouraged to monitor the IMD’s updates closely as the monsoon season approaches. With the forecast indicating a normal to above-normal monsoon, India is well-positioned to navigate the challenges of the 2025 monsoon season.
