In early August 2026, Brazilian institutions began hosting discussions and panels to address the projected emergence of a ‘Super El Niño’ expected between late 2026 and early 2027. These initial efforts focused on climate projections, social impacts, and adaptation strategies, including training for community leaders and regional panels in Paraíba to discuss sustainability in the Sertão region. Following these discussions, the Brazilian government intensified its response through the El Niño Situation Room. Coordinated by the Casa Civil, this body held its third meeting to organize regionalized preparation measures. The strategy targets specific risks, such as drought in the North and Northeast, intense rainfall in the South, and high temperatures in the Southeast and Central-West. Federal agencies, including Inmet and Cemaden, are monitoring Pacific Ocean water temperatures, which remain above average. By mid-August, the government implemented a regionalized strategy to mitigate these impacts. In the North and Northeast, efforts to manage drought include installing decentralized structures of the Unified Health System (SUS) in Manaus, Belém, and Porto Velho to accelerate medical assistance. To ensure food security in drought-stricken or isolated areas, the government will utilize the Food Acquisition Program (PAA) and the National Supply Company (Conab). In the South, authorities are bracing for intense rainfall, with short-term forecasts predicting accumulations of up to 200 millimeters within seven days. Meanwhile, the National Civil Defense has conducted workshops across ten states to align emergency response flows and information sharing among local managers. By August 12, the situation escalated as the U.S. National Oceanic and Atmospheric Administration (NOAA) increased the probability of a ‘very strong’ El Niño to 90%, noting a 69% chance of it being one of the most intense events since 1950.
