What Happened

The India Meteorological Department (IMD) has officially confirmed the onset of El Niño conditions over the equatorial Pacific Ocean, raising concerns for India's 2026 southwest monsoon and kharif crop season.
IMD has revised its 2026 southwest monsoon forecast downward to 90% of the Long Period Average (LPA) — classifying it as "below normal" — with a 35% probability of a deficient season (below 90% of LPA), more than double the historical base rate of 16%.
Climate models indicate El Niño will strengthen between July and September, coinciding with the peak of India's monsoon season, when the bulk of annual rainfall is received.
The Indian Ocean Dipole (IOD) is projected to remain neutral, offering no compensating offset to Pacific warming's moisture-suppressing effects on the monsoon.
Around 200 districts have been flagged by the Agriculture Ministry as high-vulnerability zones under the weak monsoon forecast.
A deficient kharif season threatens food grain output, risks pushing food inflation higher, and could reduce rural incomes and farm employment.

El Niño-Southern Oscillation (ENSO) Mechanism

The El Niño-Southern Oscillation (ENSO) is a recurring climate pattern driven by sea surface temperature (SST) fluctuations across the tropical Pacific Ocean. During an El Niño event, trade winds weaken and warm surface water pools in the central and eastern Pacific, altering atmospheric circulation patterns globally. This disrupts the Walker Circulation — the large-scale east-west atmospheric loop over the Pacific — which in turn suppresses moisture-laden winds reaching the Indian subcontinent. El Niño cycles typically last 12 to 18 months and recur every 2–7 years. La Niña (the cool phase of ENSO) typically produces opposite effects, often associated with above-normal monsoon rainfall in India.

During El Niño years, India's southwest monsoon rainfall historically falls to 86–92% of LPA
Strong El Niño phases have cut national rice production by an average of 3.4 million tonnes
Paddy yield declines of 10–20%, cotton yield declines of 12–25%, and groundnut failures in severe El Niño years are documented
Impact on kharif crops is 2–3 times greater than on rabi crops due to the timing of peak El Niño intensity during the monsoon season
The 2026 El Niño is tracking as a potential "super" El Niño according to some climate models

Connection to this news: The IMD's confirmation of El Niño onset and its forecast of below-normal monsoon (90% of LPA) directly invokes this mechanism — warm Pacific SSTs are expected to weaken India's monsoon circulation during July–September, the critical rainfall window.

Indian Ocean Dipole (IOD)

The Indian Ocean Dipole (IOD) is an ocean-atmosphere interaction in the Indian Ocean, measured as the difference in sea surface temperatures between the western Indian Ocean (near the Arabian Peninsula) and the eastern Indian Ocean (near Sumatra). A positive IOD — warmer western, cooler eastern Indian Ocean — is associated with above-normal monsoon rainfall in India and can partially offset El Niño's drought-inducing effects. A negative IOD tends to suppress monsoon rainfall further. A neutral IOD provides no such modulation.

Positive IOD years (e.g., 2019) have moderated El Niño's adverse monsoon effects
IOD is measured using the Dipole Mode Index (DMI)
The IOD and ENSO together explain a significant portion of year-to-year variability in India's southwest monsoon
In 2026, the IOD is forecast to remain neutral — removing a key natural buffer against El Niño

Connection to this news: The neutral IOD forecast removes the compensating mechanism that has historically cushioned El Niño-driven monsoon deficits, making the 2026 kharif outlook structurally more vulnerable than in some past El Niño years.

Kharif Season and Agricultural Dependence on Monsoon

Kharif crops are summer-sown crops planted at the onset of the southwest monsoon (June–July) and harvested in September–October. Major kharif crops include paddy (rice), maize, sorghum (jowar), pearl millet (bajra), cotton, groundnut, soybean, and sugarcane. Nearly half of India's arable land is dependent on southwest monsoon rainfall, making kharif output closely tied to monsoon performance. A deficient monsoon directly reduces soil moisture and irrigation availability in rainfed regions, compressing both crop area and yields. This then feeds through to food grain stocks, retail food prices, and the rural economy.

Kharif season: June–October (sowing: June–July, harvest: September–October)
Key crops: paddy, cotton, maize, groundnut, soybean, bajra, jowar
Rabi crops (wheat, mustard, gram) sown October–November; less directly impacted by monsoon, but can carry over soil moisture deficits
Pradhan Mantri Fasal Bima Yojana (PMFBY) — the flagship crop insurance scheme — covers kharif and rabi crops against weather-related losses
The Long Period Average (LPA) is calculated over 50 years; below-normal is defined as 90–95% of LPA; deficient is below 90%

Connection to this news: The 35% probability of a deficient monsoon — more than double historical norms — poses a direct threat to the 2026 kharif season, with rice, cotton, and groundnut output most at risk. This could translate into food inflation pressures and reduced rural incomes in the second half of 2026.

Food Inflation Transmission Mechanism

A deficient monsoon reduces agricultural output, which lowers supply of food grains, vegetables, and oilseeds. With demand relatively inelastic in the short term, reduced supply pushes up food prices. Food inflation then feeds into headline CPI, given food's significant weight (36.75% in the new 2024-base CPI series). Higher food prices disproportionately hurt lower-income households that spend a larger share of income on food. The Reserve Bank of India monitors food inflation closely because persistent food price pressures can trigger generalised inflation through wage-price spirals and inflation expectations.

Food & beverages weight in CPI (new 2024-base): 36.75%
RBI's inflation target: 4% ± 2% (tolerance band: 2–6%)
A monsoon deficit of 10% historically translates to food inflation increasing by 2–3 percentage points with a 3–6 month lag

Connection to this news: If the below-normal 2026 monsoon materialises, food price pressures are expected to intensify in September–December 2026, complicating the RBI's inflation management and potentially constraining any monetary easing cycle.
