Extreme weather conditions continue to impact multiple regions across the Americas and Europe. In Mexico, the monsoon season persists with heavy rains in Sinaloa, Sonora, and Nayarit, while Yucatán and Quintana Roo face extreme heat. In Baja California, the Secretaría de Salud has confirmed 49 deaths linked to extreme temperatures, with 47 occurring in Mexicali. High humidity and temperatures reaching 45°C have prompted the activation of the Plan DN-III-E. In South America, the simultaneous effects of coastal El Niño and global El Niño phenomena are driving significant climatic shifts. In Peru, Senamhi has issued a “national red alert” due to a heatwave affecting more than 20 regions. To mitigate risks from heavy rains, educational authorities in Ancash and La Libertad have moved to conclude the 2026 school year early. New projections suggest the El Niño phenomenon may maintain an “extraordinary magnitude” until January 2027. Experts from Interbank and the Lima Chamber of Commerce warn that intense rainfall could increase transport costs by 20% to 30% due to infrastructure disruptions. Economic forecasts for Peru have become more cautious as a result of these climatic risks. BBVA Research has lowered its GDP expansion projections for both 2026 and 2027 to 2.9%, down from previous estimates of 3.1% and 3.5%. The El Niño phenomenon is expected to negatively impact agriculture and fishing, potentially slowing growth to between 1% and 2% in the first half of 2027. Additionally, inflation is projected to reach approximately 5% by 2026, driven by rising fuel and transport costs. In Colombia, the Regional Autonomous Corporation (CAR) has issued early warnings for potential El Niño conditions, with the Río Negro recording only 2% of its usual volume. Simultaneously, Ecuador is experiencing severe flooding, with the National Secretariat for Risk Management reporting that eight rivers have overflowed. Economic assessments underscore these vulnerabilities; a Goldman Sachs report warns that the 2026 El Niño could cause significant GDP contractions in Ecuador and Brazil, while Argentina may see a 2.57 point boost from improved agricultural water conditions.
