The wildfire in Niebla became one of the most severe emergencies in recent years, with authorities initially saying the blaze was beyond containment. More than 20,000 hectares were within the fire’s perimeter, and over 500 people had been evacuated from their homes in Huelva and Sevilla provinces as a precaution. This was an early estimate of the area enclosed by the fire, not the final burned-area figure. The situation remained critical as the flames advanced rapidly and emergency services faced major operational challenges.
On Monday, authorities ordered the evacuation of the villages of Las Delgadas and Sorromero in Zalamea la Real, adding to the number of displaced residents. The basic settlement of El Madroño and its four outlying hamlets, El Álamo, Juan Antón, Juan Gallego and Villargordo, were also cleared. Evacuees were taken to the Teatro Municipal Ruiz Tatay in Zalamea la Real, prepared to accommodate both new arrivals and those already displaced. The evacuation route covered approximately 14 kilometers and used the HU-6104, A-476 and N-435 roads.
Antonio Sanz, then Vice President and Minister of Presidency, Health and Emergencies, reported from the Advanced Command Post that the fire’s behavior was unpredictable and dangerous. The affected field consisted mainly of eucalyptus, dehesa and pine forests. The Junta de Andalucía said the estimate of more than 20,000 hectares referred to the area inside the fire perimeter, not the total surface burned. Sanz said weather conditions offered no relief, while emergency teams faced hazardous convection that could generate secondary fires kilometers from the basic front. In some cases, aerial units had to airlift isolated ground teams surrounded by flames because intense convection made water drops ineffective.
Strong southwesterly winds began pushing the fire northeastward early Monday, accelerating its spread and limiting the effectiveness of firefighting efforts. Sanz emphasized that the fire’s scale and behavior, rather than a lack of resources, were the basic obstacles to containment. The risk of new secondary outbreaks and the reduced impact of aerial operations continued to threaten the field and the safety of emergency personnel.
Despite these setbacks, some progress was made overnight. Controlled burns were carried out in the northern sector, and mechanized firebreaks were established in the northeast, using already burned areas as support. Additional burns south of Berrocal reinforced defensive lines. The basic objective for Monday was to contain the northern flank and the fire’s head, focusing efforts between El Pozuelo, Marigenta and Berrocal with heavy machinery, ground teams and further controlled burns. In the southeast, bulldozers and ground crews worked along the black perimeter line toward the northeast. A secondary contingency line was also set up between Aznalcóllar and Berrocal in case the fire breached the initial defenses.
More than 600 personnel were deployed, supported by 26 aircraft. Resources included 15 specialist firefighter groups, 11 fire engines, 10 heavy machines and 250 members of the Military Emergency Unit, along with three additional machines. The goal was to reduce the fire’s intensity and limit its spread, but the region’s terrain and shifting winds complicated operations. Authorities warned that stabilization was not expected soon and that several days of intense work lay ahead. Sanz described the response as a prolonged struggle, with no immediate improvement in weather conditions.
Further evacuations remained possible, with the hamlet of La Delgada in Zalamea la Real and Madroño in Sevilla on alert. Francisco Toscano, Acting Government Delegate in Andalucía, said the weather was unfavorable for firefighting and stressed that difficult decisions had been and would continue to be made as the crisis unfolded.
Wildfires have become an increasing concern across Spain, with mass evacuations also reported in Segovia and Castellón. The relocations highlighted the growing challenge of managing large-scale blazes under adverse conditions. More details on those incidents are available in this report on evacuations in Segovia and Castellón.
Spain’s wildfire season has lengthened in recent years, with climate factors and land-management practices contributing to more frequent and intense incidents. The Niebla fire renewed calls for coordinated emergency response and sustained investment in prevention and rapid intervention capabilities. During the emergency, local authorities prioritized resident safety and the protection of critical infrastructure.
The fire began on 6 August 2026 at the Raboconejo site in Niebla. As the emergency developed, the reported evacuation total rose: RTVE later said more than 700 residents from localities in Huelva and Sevilla had been evacuated preventively, with Berrocal identified as the municipality most severely affected. The fire was eventually declared extinguished after 15 days of firefighting operations. Juanma Moreno, president of the Junta de Andalucía, described it as “estabilizado” once it was no longer advancing.
Later estimates of the area burned varied. The Junta put the figure at about 33,000 hectares, while regional reporting gave estimates of approximately 38,000 hectares and 39,821 hectares; these figures refer to burned or affected land, unlike the initial estimate of more than 20,000 hectares within the perimeter. Canal Sur compared the blaze with the 2004 Riotinto fire, which burned roughly 34,000 hectares. The Niebla fire formed part of an exceptionally severe 2026 season in Andalucía, during which roughly 60,000 hectares were reported burned across the region.
Berrocal became the area hardest hit. Canal Sur reported that about half of the municipality’s territory had burned, while the Junta’s estimate put the affected share at 62 to 63%; local observers cited in the report considered the proportion higher. The damage extended beyond vegetation to risks of soil loss and erosion, including possible effects on the Corumbel reservoir. The Junta estimated that immediate erosion-control and soil-protection measures would require €10.2 million, while longer-term reforestation plans included replacing eucalyptus stands with native species.
The consequences also extended into wildlife management. After the emergency, the Dirección General de Política Forestal y Biodiversidad denied several requests to hold monterías in hunting areas affected by the fire in Huelva and Sevilla. Environmental groups argued that burned habitat had deprived wildlife of shelter, food and refuge, and sought suspension of hunts in the affected areas.
