Aragón is facing its fourth major wildfire of the summer after a fast-moving blaze broke out Wednesday afternoon in Castillonroy, Huesca, in the La Litera region. In just 12 hours, the fire consumed 400 hectares, half of the local forest mass, prompting urgent action from emergency services and local authorities.
The fire broke out in an area already scarred by flames: just weeks ago, Tamarite, another municipality in La Litera, lost more than 4,000 hectares. Regional officials attributed the latest outbreak to soaring temperatures and dry thunderstorms, and quickly escalated emergency protocols. By Wednesday night, the government had sent an ES-Alert message to the 800 residents of nearby Albelda, instructing them to stay indoors for their safety. The confinement order was lifted Thursday morning, but the operational alert level remains at 2, with the Military Emergency Unit (UME) still deployed.
Firefighting efforts have mobilized 200 personnel, including eight ground brigades and five helitransported teams. Seven fire engines and five helicopters have also been deployed. Support has come from Huesca and Zaragoza fire departments, alongside national aerial resources. Regional emergency chief Roberto Bermúdez de Castro praised local farmers for creating firebreaks by ploughing their fields. They also helped contain the flames directly.
The fire has also damaged infrastructure. It severed two power lines, leaving Castillonroy with limited electricity and mobile coverage. Authorities are coordinating with Endesa to restore service, but the ongoing heatwave is slowing recovery. The national N-230 road has reopened, while the A-140 remains closed to give emergency vehicles clear access.
Weather conditions continue to challenge responders. AEMET forecasts persistently high temperatures in Aragón, with readings expected to exceed 40 degrees Celsius into next week. Low humidity and strong southern winds are expected to increase fire risks, particularly in the late afternoon and evening. Bermúdez de Castro described a run of “tropical days” that has stretched emergency teams after two relentless weeks.
AEMET’s assessment described summer 2026 as the warmest in Aragón’s recorded series, with average temperatures 3.4°C above normal. The region recorded 61 days meeting heatwave conditions and 64 tropical nights. Temperatures exceeded 40°C on 23 days. Those conditions formed the backdrop to a season of repeated heat stress and difficult firefighting operations.
The heat also had a broader public-health impact: Spain’s Daily Mortality Monitoring System (MoMo) estimated 235 temperature-attributable deaths in Aragón between June and September. July accounted for 109 of the estimated deaths, compared with 45 in June, 65 in August and 16 in September.
Aragón did not receive European funds for wildfire prevention this year because last summer saw minimal fire activity. The regional government now faces the dual challenge of managing ongoing harvests while maintaining exhausted firefighting crews, making operational decisions increasingly complex.
The fire season extended beyond Aragón. Provisional figures attributed to Spain’s Ministry for the Ecological Transition put the national forest area burned at 275,154 hectares by 20 September 2026. That was slightly above the 274,777 hectares recorded over the same period in 2025, and 2.5 times the average for the previous decade. Interior regions accounted for 56.55% of the affected area. Mediterranean regions made up 27.10%, while the northwest accounted for 16.33%.
Wildfires have become a recurring threat across Spain, with regions such as Navarra also grappling with heat-related emergencies. During the San Fermín festivities in Pamplona, for example, authorities prioritized emergency services and public safety amid record temperatures, as detailed in this report on the San Fermín 2026 launch.
Longer, hotter summers and more frequent dry storms heighten Spain’s vulnerability to wildfires. Aragón’s situation points to the need for sustained investment in prevention and rapid response, along with coordination among local communities, regional authorities and national resources. The ongoing fires threaten natural landscapes and disrupt daily life. They also affect infrastructure and the agricultural sector, which remains critical to the region’s economy.
