Odisha, Odisha — South Asia braces for below‑average monsoon in 2026 due to an El Niño threat.

The India Meteorological Department (IMD) released an early warning on 12 April, indicating that the developing El Niño in the central Pacific is likely to suppress the southwest monsoon over the Indian subcontinent. Seasonal forecasts from the World Meteorological Organisation (WMO) have corroborated the IMD’s assessment, projecting a 30 percent reduction in rainfall across the eastern coastal belt compared with the long‑term average. Such a deficit could affect water reservoirs, agricultural sowing windows and hydro‑electric generation throughout the region.

Background The El Niño phenomenon, characterised by unusually warm sea‑surface temperatures in the equatorial Pacific, typically disrupts the monsoon circulation by weakening the low‑level westerly flow that transports moisture from the Arabian Sea and Bay of Bengal. Historical records show that strong El Niño events in 1997‑98 and 2015‑16 coincided with delayed onset and reduced precipitation over Odisha and neighbouring states. Climate models employed by the IMD and the National Centre for Medium‑Range Weather Forecasting (NCMRWF) suggest that the 2026 episode will be moderate in intensity but persistent, with sea‑surface temperature anomalies remaining above +0.8 °C for at least three months. The forecasted deficit is expected to be most pronounced in the central and southern districts of Odisha, where average monsoon rainfall contributes over 70 percent of the annual water budget.

Community Impact Farmers in the Mahanadi basin have already expressed concern, as the sowing of kharif crops such as paddy and pulses depends on timely monsoon rains. A shortfall of 150 mm could reduce paddy yields by up to 20 percent, according to the Odisha State Agricultural Department. Reduced rainfall will also lower groundwater recharge, threatening drinking‑water supplies in rural villages that rely on shallow wells. Health officials have warned that drier conditions may increase the incidence of water‑borne diseases, while the diminished flow in rivers could hamper navigation and fisheries that support coastal livelihoods. Urban areas, including Bhubaneswar, may experience lower reservoir levels, prompting water‑conservation advisories for households and industries.

What Happens Next State authorities have convened an emergency task‑force comprising the IMD, the Water Resources Department and the Department of Agriculture. The task‑force has issued guidelines for water‑saving irrigation techniques, such as laser‑guided drip systems, and has accelerated the distribution of drought‑resistant seed varieties to vulnerable farmers. Monitoring stations have been upgraded to provide real‑time rainfall data, enabling the department to issue timely alerts through the state’s disaster‑management portal. The central government has pledged additional funds under the National Disaster Management Fund to support relief measures if the monsoon deficit translates into crop failure. Residents are advised to conserve water, adopt rain‑water harvesting where feasible, and stay informed through official bulletins.

Continued observation of the El Niño’s evolution will determine whether the monsoon deficit intensifies or eases. The IMD has committed to weekly updates, and the state’s public‑information campaigns will keep communities apprised of any changes in weather patterns or relief schemes.
