Super El Niño 2026-2027: Sri Lanka Faces Dual Threat of Drought & Flash Floods 📉

• Climate Indicators & Status: Pacific sea surface temperatures reached +1.7°C in mid-June 2026, confirming a strong El Niño. The CPC indicates a 97% probability of it persisting into early 2027. Current warming is stronger than early phases of the 1997 and 2015 events. • Indian Ocean Counter-Drivers: • Indian Ocean Dipole (IOD): ~60% probability of a positive IOD developing by late 2026, which may offset El Niño drying by boosting Second Inter-Monsoon (Oct–Nov) rainfall. • Madden-Julian Oscillation (MJO): Currently weak and unlikely to impact weather in the coming months. • Agricultural & Hydropower Risks: • Drier conditions threaten the Northeast Monsoon (Dec–Feb), a critical water source for paddy cultivation and reservoir levels in the Dry Zone. • Positive IOD could cause intense downpours with longer dry spells, risking flash floods/landslides without filling water capacity evenly. • Late IOD onset increases exposure to severe dry spells, impacting tea, paddy/rice cultivation, irrigation, and hydropower generation. • Outlook: Key developments from August–September 2026 will determine whether Sri Lanka faces severe dry spells or localized floods. Stakeholders are advised to prepare for both scenarios.
