Beyond 'normal': why India's 2026 monsoon forecast hides more than it reveals

Every year in February, the India Meteorological Department releases its first long-range monsoon forecast. Every year, the forecast says something remarkably similar: rainfall will be "normal" — defined as 96-104% of the Long Period Average. And every year, somewhere in India, people die because "normal" turned out to be a catastrophically misleading word.

In 2025, national rainfall was 98% of the LPA. "Normal." But 147 districts across Rajasthan, Maharashtra, and Karnataka faced drought. Simultaneously, 89 districts in Assam, Bihar, and West Bengal experienced severe flooding. The national number was fine. The national number was useless.

This is the monsoon's cruelest paradox: the country gets enough rain. It just doesn't get it in the right places, at the right times, for the right crops.

What the 2026 Forecast Actually Says

IMD's early statistical model — released in late February, ahead of the more detailed April forecast — predicts 2026 monsoon rainfall in the range of 96-104% of LPA. The model accounts for sea surface temperatures in the Pacific (ENSO), the Indian Ocean Dipole, Eurasian snow cover, and atmospheric circulation patterns.

The key variable this year: developing La Niña conditions. La Niña — characterised by cooler-than-average Pacific sea surface temperatures — historically correlates with above-average monsoon rainfall in India. If La Niña strengthens by June, late-monsoon rainfall (August-September) could be significantly above normal, particularly in the Indo-Gangetic plain and northeast India.

"La Niña is generally good news for total monsoon volume," said Dr. M. Rajeevan, former Secretary of the Ministry of Earth Sciences. "But it is complicated news for flood-prone regions. Bihar and Assam may receive 20-30% above-normal rainfall in September. That's not a gift — that's a disaster."

The Farmer's Dilemma

Indian agriculture employs 42% of the country's workforce — roughly 260 million people. Despite decades of investment in canal irrigation, drip irrigation, and borewells, 52% of India's cultivated area remains entirely dependent on monsoon rainfall. For these farmers, the difference between a good monsoon and a bad one is not an academic question. It is the difference between feeding their families and falling into debt.

The monsoon determines kharif crop yields (rice, pulses, cotton, sugarcane), which in turn determine rural income, rural consumption, food inflation, and — through a chain of economic effects — interest rate decisions by the Reserve Bank of India.

"The monsoon is India's real finance minister," goes a saying among agricultural economists. It is not entirely a joke.

Pre-Monsoon Warning Signs

Central Water Commission data reveals a concerning baseline: as of February 2026, India's 150 major reservoirs hold 12% less water than the 10-year average for this period. The deficit is concentrated in southern and western India — Maharashtra, Karnataka, Telangana, and Tamil Nadu — where last year's uneven monsoon left reservoir levels underreplenished.

If the 2026 monsoon arrives late — or if early-monsoon rainfall (June-July) is below average before La Niña kicks in later — these regions face a critical irrigation gap during the kharif sowing window.

What Needs to Change

The policy challenge has evolved. India's monsoon problem is no longer "will it rain enough?" National averages, over the past 20 years, have stayed stubbornly close to normal. The problem is variance — rainfall that arrives in shorter, more intense bursts, separated by longer dry spells, distributed unevenly across districts.

This pattern — consistent with climate change projections for South Asia — demands three responses that India has been slow to implement:

1. District-level forecasting: IMD's national and state-level forecasts must be supplemented by district-level predictions that farmers can actually act on. IMD has improved granularity, but implementation at the last mile — getting the forecast into the hands of the farmer planting rice in Darbhanga — remains weak.

2. Crop diversification: India's cropping pattern remains dominated by water-intensive crops (rice, sugarcane) in regions that can no longer guarantee adequate water. Shifting farmers to millets, pulses, and oilseeds requires not just policy incentives but functioning markets for those crops.

3. Flood-drought management: The same monsoon that causes flooding in eastern India causes drought in western India. Inter-basin water transfer — an idea discussed for decades — remains politically toxic and infrastructurally unbuilt.

The Number That Matters

IMD will release its updated forecast in April — with more granularity, more confidence, and more data. But the number that matters is not the national average. It is the rainfall in the 236 districts where farmers have no irrigation backup, no crop insurance payout, and no margin for error.

For them, "normal" is not reassuring. It is irrelevant. What matters is whether it rains on their field, in their sowing window, at the intensity their crop needs. And that question, even in 2026, remains one that Indian meteorology cannot reliably answer.
