Spain is facing one of its most intense wildfire episodes in decades, with more than 72,000 hectares burned in just two weeks this July. Unlike previous years, marked by numerous scattered fires, this surge is driven by a handful of massive, fast-moving blazes concentrated in central regions. The most impressive outbreaks erupted between Thursday and Friday across Almorox (Toledo), Burgohondo (Ávila), and the Madrid municipalities of San Martín de Valdeiglesias and Villa del Prado, all within 40 kilometers of each other. The wider scale of the season became clear in later European Forest Fire Information System (EFFIS) figures: by 21 October, Spain had recorded 301,413 hectares burned, equivalent to 43% of the European Union’s burned area. Fires in Madrid, Ávila, and Toledo had already burned more than 77,000 hectares by the end of July.
The fire in Burgohondo alone consumed 8,000 hectares in under 48 hours, nearly merging with neighboring fronts. Extreme heat, low humidity, and strong winds drove the simultaneous fires to expand aggressively. Forestry engineer Ferran Dalmau said fires in such close proximity interact rather than compete, complicating containment as resources must be divided among multiple emergencies. The Burgohondo fire began on 22 July; Reuters reported that sparks from heavy machinery ignited vegetation near the village. Strong winds drove it into a larger complex that joined fires near Almorox and San Martín de Valdeiglesias. More than 60,000 people were evacuated as the emergency evolved, and regional tallies put the complex’s final burned area at about 63,000 hectares when the last hotspots were extinguished on 3 October.
Another major blaze, in La Mierla (Guadalajara), was stabilized five days ago but spread so rapidly across such a vast area that it was expected to rank among Spain’s largest recorded wildfires. Preliminary data suggested it burned around 35,000 hectares, including 20,000 hectares of the Sierra Norte de Guadalajara Natural Park, and stretched over 40 kilometers. A later assessment put the final affected area at 34,447 hectares, with most of the damage inside the protected natural area. The fire began on 16 July and was declared extinguished on 4 September, after 51 days. It forced the evacuation of about 1,200 residents in 34 municipalities, while residents of another 14 municipalities were confined. Although the blaze was initially associated with harvesting activity involving a combine harvester, its cause remained unresolved three months after ignition.
After suppression ended, attention shifted to recovery. During an assessment tour across 75 kilometers of the burned field, forest firefighter Juan Jorge de la Rosa described a continuous field of ash and said the priority was “to focus a little on recovery,” EFE Verde reported. The fire also affected areas beyond the burn zone: ozone peaks and wildlife displacement were reported in the Sierra Norte, adding to the need for long-term ecological restoration.
Between July 9 and 22, the area affected by large wildfires, those exceeding 500 hectares, reached levels not seen since 1983, when comparable official records began. The 72,000 hectares lost in this short period surpass the annual totals of 31 of the last 43 years. Only a few years, such as 2025, 1994, and 2022, saw similar or greater devastation, often because of either a high number of medium-sized fires or a few exceptionally large ones. EFFIS-based assessments later counted 49 large wildfires across Spain by 19 October, against a ten-year average of 23; about 241,000 hectares were concentrated in those large fires. July alone accounted for more than 168,000 hectares in that assessment.
Recent data show a clear trend: while the number of large wildfires has halved over the past four decades, the average size of each has more than doubled. In the 1980s and 1990s, Spain typically saw about 50 large fires per year. From 2010 to 2025, that figure dropped to 26, but each fire now covers a much larger area. Satellite data from the European Copernicus program confirm the shift toward fewer, more explosive and rapidly spreading incidents.
When fires cluster in a short timeframe, they put extraordinary pressure on emergency services. If several major blazes ignite simultaneously, as they did this July, authorities must prioritize firefighting resources, including aircraft, crews, and heavy machinery, often focusing on protecting population centers. On 24 July, Spain declared an emergency situation in the Community of Madrid and Ávila province in Castile and León as fires spread across several fronts. Evacuations at that stage involved approximately 11,500 people, including more than 10,000 in Madrid and about 1,500 from a rural-tourism complex and residential area in El Tiemblo, linked to the Burgohondo fire. The National Civil Protection System is designed to respond when regional capacity is overwhelmed, allowing state-level intervention and unified command in emergencies of national interest.
July and August remain Spain’s most critical months for wildfires, accounting for 70% of the annual burned area. So far this year, more than 93,000 hectares have been lost to large fires by July 22, nearly four times the historical average for this point in the season. The final impact will depend on August’s conditions: in nearly half of the past 43 years, less than 10,000 hectares burned in August, and in seven years, the figure was below 5,000. If major fires are avoided in the coming weeks, the season could still end below record levels. By 5 July, but, Spain had already recorded 50,750 hectares burned, more than twice the area registered by the same date in 2025.
Last year’s wildfire crisis was even more concentrated. In August 2025, more than 130,000 hectares burned in Ourense alone in a single week, while 40 large fires across Ourense, Zamora, and León burned more than 312,000 hectares in total. This pattern of clustered, high-intensity fires, now repeating south of Madrid and Ávila, makes containment especially challenging. The situation echoes recent events in Madrid, where a series of wildfires forced mass evacuations and stretched emergency services to their limits, as detailed in this report on the Madrid wildfire crisis. Reuters’ wider assessment put the 2026 national toll above 300,000 hectares and reported at least 21 wildfire-related deaths. It also pointed to rural depopulation and unmanaged vegetation as factors that heighten vulnerability in landscapes with fewer residents and less routine land management.
Official statistics on large wildfires are compiled from the Ministry for Ecological Transition’s General Statistics of Forest Fires (EGIF) for 1983-2022 and the European Forest Fire Information System (EFFIS) for 2023-2026. The two systems generally agree on the number of major incidents, but EFFIS tends to report slightly larger affected areas because it includes non-forest land. The cumulative figures vary by reporting date: a later assessment put the total at 301,299 hectares by 19 October, while figures published for 21 October reached 301,413 hectares. Data for 2026 remain provisional. Historical comparisons are limited to post-1983 records, as earlier data lack consistent location details.
The methodology focuses on each year’s worst 14-day period, assigning each fire to its start date to track how quickly damage accumulates. This approach highlights the growing challenge posed by fewer but larger and more destructive wildfires in Spain’s changing climate.
