Overview
- NOAA’s Oct. 8 update shows more than an 83% chance that El Niño will remain strong or very strong through January–March 2027, increasing the risk of heavy rains and temperature extremes.
- Peru’s ENFEN raised the odds of an extraordinary El Niño from about 8% in June to 52% in September, and coastal sea temperatures have already exceeded peaks recorded in 1983 and 1997.
- The national water authority reported that the government prioritized 536 coastal risk points but only about 17% had works in execution as of Oct. 7, leaving most structural fixes stalled when the rainy season nears.
- More than 6 million hectares, roughly 53% of Peru’s farmland, are at high flood risk with Lambayeque especially exposed, and economists warn the event could cut more than one full percentage point from 2027 GDP growth.
- Experts say focusing mainly on drains, roads and dams will not protect the most vulnerable and urge rapid steps to open accessible shelters, provide evacuation transport and secure medical continuity for older adults, people with disabilities, low-income families and people experiencing homelessness.
