South American Nations Prepare for Potential Super Niño Event 2026 to 2027

Meteorological agencies and governments across South America are preparing for the El Niño phenomenon, with some forecasts indicating a high probability of an exceptionally strong event known as a Super Niño. In Ecuador, the government has declared a red alert across the entire national territory, warning that the current event could be the most intense ever recorded and may surpass previous major events from 1982, 1997, and 2015. Peru's multisectoral commission, ENFEN, has increased the probability of an extraordinary Coastal Niño to 62 percent between September 2026 and January 2027, forecasting extreme marine warming and potential record air temperatures along the coast. Colombia's Ministry of Health has issued directives to reinforce hospital preparation, focusing on epidemiological surveillance and water quality to mitigate risks associated with high temperatures and water scarcity. In Brazil, 399 municipalities in the Center West region are on alert for forest fires due to predicted delays in rainfall and temperatures above the average. Meanwhile, reports for Argentina indicate a probability higher than 90 percent that the phenomenon will persist through the southern spring and summer, which is expected to increase rainfall and storms in the Pampean region, the Litoral, and the northeast. Environmental impacts are already being observed, including the displacement of anchoveta stocks in Peru and droughts in Central America and Indonesia. All three reports originate from center right outlets, and they maintain a consistent focus on the technical risks and the necessity of government preparedness.
