Brazil fire and heat crisis intensifies
Overview
Brazil’s dry-season fire and heat crisis continues to intensify through late October 2026, driven by a powerful El Niño event. In the Amazon, fire outbreaks surged significantly; September saw a 74.2% increase in outbreaks compared to 2025. In Amazonas, 2026 fire counts reached over 3,000, triple the 2025 total. While October hotspots showed a 74% decrease, smoke from the Lower Amazonas and Pará continues to cause health issues and school suspensions in Manaus.
In response to the crisis, the federal government approved R$ 45.2 million for 47 humanitarian assistance plans in Amazonas, where a task force of 18 aircraft has deployed 3.2 million liters of water over two weeks. In Pará, the Ministry of Integration and Regional Development approved R$ 3.9 million to support 24 municipalities. The National Civil Defense has also met with representatives from western Pará to coordinate emergency responses to extreme drought and advancing wildfires, particularly in areas like Monte Alegre where monitoring over 350 communities is difficult.
Regional emergencies have expanded. In Mato Grosso do Sul, rising temperatures and intense heat threaten the Pantanal, which has recorded 166 fire events affecting over 124,400 hectares. In Santarém, Pará, flames are threatening homes, crops, and traditional territories. Air quality remains a critical concern; while Manaus has seen moderate levels, cities such as Itacoatiara, Itapiranga, Nhamundá, and Urucurituba have recorded very poor or unsatisfactory pollutant levels due to smoke from thousands of outbreaks.
