El Niño phenomenon strengthens with historic intensity projected for 2026-2027

The El Niño-Southern Oscillation (ENSO) phenomenon is strengthening, with experts projecting a potentially historic event. Indicators show sea surface temperatures in the Equatorial Pacific reached 2.5 °C to 5 °C above historical averages in July. There is a 69% probability that the 2026/2027 cycle will be the most intense since 1950, with a greater than 90% chance of a very strong event occurring between late 2026 and early 2027.

The climatic shift is expected to have diverse and severe global impacts. In Mexico, the phenomenon threatens to exacerbate water scarcity and drought, particularly in the north, while the Pacific coast may face increased cyclone activity. In South America, regions like Colombia, Venezuela, and parts of Chile may face water deficits, while Brazil faces risks to its agricultural sector and electrical system stability. In Asia, the Japan Meteorological Agency expects the phenomenon to persist through the winter, potentially influencing typhoon activity and snowfall patterns.

Beyond immediate weather changes, the intensification of El Niño poses significant health and economic risks. Scientists warn of increased disease transmission, such as dengue, and potential food insecurity due to crop failures in soybean and corn. In Brazil, the Ministry of Mines and Energy is preparing the electrical grid for altered rainfall patterns that affect hydroelectric reservoirs.
