Concerns Rise as IMD Downgrades Monsoon Projections for 2026

The India Meteorological Department (IMD) has revised its forecast for the 2026 southwest monsoon, predicting that the country will only receive 90% of the Long Period Average (LPA) rainfall from June to September. This adjustment marks a decline from the previous April estimate, which had anticipated 92% of the LPA, raising significant agricultural and water resource concerns.

Meteorological officials highlight that alterations in oceanic and atmospheric conditions in the Pacific are at play, primarily attributed to the increasing likelihood of El Nino. This climate phenomenon, characterized by warmer sea surface temperatures in the central and eastern Pacific Ocean, can significantly disrupt global weather patterns, often resulting in a diminished monsoon for India.

Experts emphasize that the emergence of El Nino tends to weaken the monsoon circulation, redirecting moisture-laden winds and consequently leading to lower rainfall across many regions of India. According to the spatial forecast, while Northwest India may still experience close to normal rainfall, areas such as Central India, South Peninsular India, and Northeast India are poised for below-normal precipitation, which is critical given the region’s reliance on agriculture.

Weather scientists warn that the intensity of the El Nino event could escalate in the latter half of the monsoon, particularly from July to September. Should this occur, the resultant rainfall deficits could intensify in numerous states, stressing reservoirs, groundwater, and irrigation necessary for millions of farmers.

The IMD forecasts that June will likely see below-normal rainfall across vast portions of the country, coupled with higher temperatures that could exacerbate heat stress on crops and water supplies. However, officials express cautious optimism regarding the on-time arrival of the southwest monsoon in Kerala in the days ahead.

Agriculture specialists underline the vital role of the southwest monsoon, which typically accounts for nearly 70% of India’s annual rainfall, especially for kharif crops like rice, pulses, and oilseeds. Any substantial deficit in precipitation could adversely affect agricultural output, rural livelihood, and food prices. Authorities pledge to monitor the changing El Nino dynamics closely and issue revised forecasts as the monsoon progresses.
