Spain's largest 2026 wildfire rages as 40,000 hectares burn
Spain's largest wildfire of the year has devastated 26,000 hectares and displaced 1,200 people, compounding the infrastructural toll of a devastating fire season driven by climate change.
A wildfire in La Mierla, Guadalajara province, has consumed 26,000 hectares, making it Spain's largest blaze of 2026. Driven by high winds, the fire remains out of control with a perimeter stretching 100 kilometres. Authorities have evacuated 1,200 residents across 25 municipalities as emergency services scramble to protect regional infrastructure.
The scale of the response highlights the severe strain on public resources. A force of 655 personnel, 33 aircraft and 33 ground crews is currently battling the La Mierla blaze, with efforts on Sunday concentrating on the Gascueña and Bustares areas. "We want to stay ahead of the fire," stressed Mercedes Gómez, the Minister of Sustainable Development for Castilla-La Mancha.
The La Mierla blaze follows a separate fire in Orés, Zaragoza, which is now contained but remains active with an 80-kilometre perimeter. Together, the two disasters have ravaged 40,000 hectares. A further 1,000 people were evacuated due to the Orés blaze, but Aragonese regional president Jorge Azcón noted the fire has "no more flames." "That doesn't mean we're going to let our guard down. The fire will continue to be brought under control," he added.
Authorities are now shifting to assess damage to homes and infrastructure in Aragon so residents can safely return. Vice President Mar Vaquero said a decision on returns "can be made in the next few days," a necessary step before local economies can resume normal activity. Further disruption hit transport and commerce on Sunday when a four-hectare fire near Barcelona closed the B-250 highway and a lane of the B-20, while a separate blaze in Badajoz triggered a Level 1 emergency before being controlled.
These events cap a brutal month for Spain, following an earlier blaze in Almeria that killed 13 people and destroyed 7,000 hectares. Scientists attribute the increasing length, intensity and frequency of heatwaves to human-driven climate change, which dries out vegetation and creates prime conditions for wildfires. For Spain's regional governments, the recurring need to deploy massive emergency resources is rapidly becoming a persistent public expenditure challenge.
