Wildland fires occur across Europe every summer, but those that erupted in Spain and France in July 2026 were among the largest and most disruptive the two countries have faced in decades. Some of the most consequential fires emerged in southwestern France's Gironde Department and Spain's Ávila and Madrid provinces in mid-July, where blazes forced hundreds of thousands of people to evacuate and destroyed hundreds of homes.
Government officials in Spain say that a fire in Ávila, after charring around 50,000 hectares (124,000 acres), is the largest on record, surpassing a blaze that burned in Larouco, Quiroga, and Oencia in 2025. NASA satellites first observed signs of the Ávila fire burning near Burgohondo on July 22 and July 23. By July 24, it had merged with fires in neighboring provinces, pushing the total area burned to 77,000 hectares, an area about the size of New York City.
The image above, captured by Landsat 9, shows charred landscapes around Burgohondo on July 29, 2026. In the false-color image, unburned vegetation appears light green, and burned areas appear brown. The two reservoirs in the center of the image were heavily affected. Flames tore through homes, restaurants, campgrounds, marinas, and other infrastructure surrounding the reservoirs, according to news reports.
