Bhubaneswar: A major international climate assessment has raised fresh concerns for India's agriculture, water security and disaster preparedness, warning that the developing 2026-27 El Niño could become one of the strongest on record.

According to a report released by the European Commission's Joint Research Centre (JRC), the emergence of an El Niño event is now "virtually certain", with climate forecasting systems indicating a 68 per cent probability that it could intensify into an "unprecedented" event by autumn. Such an event would be characterised by sea surface temperature anomalies exceeding 3°C in the Pacific Ocean's NINO3.4 region.

For India, the warning comes at a crucial time. The country's agricultural economy, water resources and food security remain closely tied to the performance of the southwest monsoon, which has historically shown vulnerability to strong El Niño episodes.

Rare Climate Warning From the Pacific

The JRC analysis, based on Copernicus Climate Change Service seasonal forecasts, suggests that all major forecasting systems are pointing towards at least a very strong El Niño during 2026. Several models indicate that the event could enter an unprecedented category later in the year.

Scientists note that El Niño alters atmospheric circulation patterns across the globe, influencing rainfall, temperatures, droughts and extreme weather events. Historically, some of India's weakest monsoon seasons have coincided with strong El Niño years.

The report warns that the impacts of this event may extend well beyond the Pacific Ocean, affecting agricultural production, water availability and food markets worldwide.

Why India Is Emerging as a Major Risk Zone

Among the most significant findings is the projected rainfall deficit across the Indian subcontinent.

The JRC's precipitation forecasts identify India as one of the regions with a strong likelihood of below-normal rainfall during both the June-August and June-November periods. Climate simulations associated with stronger El Niño categories show a pronounced drying signal over large parts of the country.

The findings reinforce long-standing scientific evidence linking El Niño events with weaker monsoon performance over India. A deficient monsoon can affect crop yields, reservoir storage, groundwater recharge and rural incomes, particularly in regions dependent on rain-fed agriculture.

The report also flags India among global agricultural zones facing negative precipitation prospects during the coming growing season, alongside parts of China, Australia, Brazil and Sub-Saharan Africa.

What the JRC Maps Reveal for Odisha

Although the JRC report does not provide state-wise forecasts, the spatial patterns visible in its temperature, rainfall, soil-moisture and tropical storm maps place Odisha in one of India's most climate-sensitive corridors.

The precipitation anomaly maps show eastern and central India embedded within a broad zone of below-normal rainfall under super and unprecedented El Niño scenarios. For Odisha, this suggests that the state's monsoon may become increasingly erratic rather than uniformly deficient. While seasonal rainfall totals could decline, the distribution of rainfall may become more uneven, with prolonged dry spells punctuated by short bursts of intense precipitation.

This signal becomes more concerning when viewed alongside the soil-moisture projections. The report's soil-moisture and SPEI maps indicate that the drying tendency over India strengthens between September and November, implying that agricultural stress may continue even after the peak monsoon months.

The temperature outlook adds another layer of concern. The JRC's simulations show eastern India sitting within a broad zone of persistent positive temperature anomalies that intensify after the El Niño peak. For Odisha, this could mean longer heat-stress periods, higher evapotranspiration rates and accelerated depletion of surface-water resources, even if intermittent rainfall events occur.

Cyclone Outlook In El Nino Season

Perhaps the most important signal for Odisha comes from reading the rainfall and storm maps together. While the dominant forecast for India remains one of rainfall deficiency, the ECMWF tropical cyclone outlook embedded in the JRC report indicates enhanced storm activity across parts of the Indian Ocean basin. For a Bay of Bengal-facing state such as Odisha, this suggests that a weaker monsoon does not necessarily eliminate the risk of extreme weather. Instead, rainfall may become increasingly concentrated in a few high-impact weather systems rather than being spread evenly through the season.

Heatwaves May Continue Well Beyond 2026

The report also projects a high likelihood of warm spells and heatwave activity across tropical and subtropical regions during the second half of 2026.

More importantly, simulations indicate that the warming effects of an unprecedented El Niño could persist after the event peaks, extending into early 2027. This phenomenon, known as thermal inertia, means elevated temperatures may continue even after ocean conditions begin normalising.

For Odisha, such a scenario could result in a shorter winter season, increased evaporation from reservoirs and an earlier onset of summer heat stress.

The combined impact of reduced rainfall and prolonged warmth could further strain water resources and agricultural productivity.

The JRC report's message is clear: while the precise intensity of the coming El Niño remains uncertain, the risk of a major climate disruption is rising. For India—and particularly for states such as Odisha that remain deeply dependent on the monsoon—the months ahead could prove crucial in determining how effectively they withstand one of the most closely watched climate events in recent years.
