A Deficit Monsoon Sets the Stage
The foundation for a challenging year ahead has already been laid. The 2026 southwest monsoon is on track to be one of the driest in years, with a rainfall deficit currently around 15% below the long-term average. This shortfall, driven by the strengthening
El Niño in the Pacific Ocean, means India enters the post-monsoon period with a significant disadvantage. The lack of adequate rain during the critical June-to-September window directly impacts the Kharif harvest and, more importantly, the amount of water stored in the country's major reservoirs.
Warmer Winters and Troubled Rabi Crops
One of the most significant post-monsoon impacts of El Niño is the likelihood of a warmer, drier winter. The phenomenon is expected to peak between November 2026 and February 2027, disrupting normal weather patterns. This could mean less-than-normal rainfall during the northeast monsoon, which is crucial for southern states, and reduced snowfall in the Himalayas. For farmers, this is a major concern for the Rabi (winter) crop season. Key crops like wheat, mustard, and gram depend on winter moisture and cooler temperatures. A warmer, drier season could lead to reduced soil moisture, affecting sowing and ultimately lowering yields, putting further pressure on food supplies and prices.
Strained Water Reservoirs and Power Supply
A weak monsoon has a direct, delayed effect on water security. Across India, 161 major reservoirs are already holding significantly less water than last year and are far below their total capacity. This deficit is expected to worsen with a dry winter. Lower reservoir levels threaten not only the drinking water supply for major cities but also the availability of water for irrigation during the Rabi season. Furthermore, it impacts hydroelectric power generation, which relies on adequate water storage. A shortfall in hydropower could increase dependence on coal and other energy sources, potentially raising power costs for consumers and industries.
The Economic Ripple Effect
The agricultural sector is the first to feel El Niño's pinch, but the effects quickly spread throughout the economy. Lower crop yields from both the Kharif and Rabi seasons can lead to sustained food inflation, which was already a concern heading into this period. Reduced farm incomes also dampen rural demand for goods and services, from tractors to fast-moving consumer goods. This slowdown in the rural economy, which forms the backbone of national consumption, can impact overall GDP growth. The Reserve Bank of India has already flagged El Niño as a potential risk to its inflation calculations, indicating how seriously the threat is being taken at a policy level.
A Multi-Season Challenge
The consensus among meteorologists is that this El Niño event could be historically strong, with its effects spilling over into 2027. A warmer winter with low snowfall in the mountains can mean less meltwater feeding rivers the following spring and summer, potentially affecting water availability even before the 2027 monsoon. Some experts have warned that a 'Super El Niño' creates a multi-season impact, where depleted soil moisture and low reservoir levels from one year carry over to the next, making a swift recovery difficult. This turns a single-season weather event into a prolonged economic and resource management challenge.
