Why Southern Europe’s Wildfires Keep Getting Bigger

Southern Europe is burning. A rapidly intensifying heatwave has triggered widespread wildfires across Spain, Portugal, France, and Greece – forcing evacuations and pushing emergency services to their limits. Smoke (particulate air pollution) from active fire zones is now spreading across Western and Central Europe, driving air pollution to unsafe levels far beyond the fire lines. 

What’s Happening: 

Since the start of 2026, around ~118,737 hectares have burned across the EU – roughly the size of Luxembourg – across approximately 962 fires, despite being mid-year conditions. 

• Wildfires are spreading across southern Spain, Portugal, Greece, and France, with ~20,000+ hectares burned across active fire zones (July 2026), driven by extreme heat and dry vegetation conditions. 

• At least 10,500 people have been evacuated across southern Europe, including ~5,000 in France (Pyrenees region) and additional mass evacuations in Spain and Greece as fire fronts expanded toward populated areas. 

• In southwestern France alone as of July 10, a major blaze has burned 28,000 hectares (69,160 acres) forcing evacuations from multiple towns and requiring hundreds of firefighters and aerial water-bombing operations. 

• Spain has recorded fires burning around 50,000 hectares, with additional evacuations and containment operations ongoing in coastal and inland zones.  

• Portugal’s major wildfire complex has burned more than 15,000 hectares in just 5 days, though parts are now partially contained under shifting wind conditions. 

• Copernicus CAMS forecasts show PM2.5 levels exceeding WHO daily limits (15 µg/m³) across large parts of southwest Europe, with smoke plumes extending across national borders and affecting regional air quality and visibility. 

Why this keeps getting worse: Climate Change and Polar Change  

This event reflects a broader trend of intensifying European heatwaves. Warming driven by human activity is increasing evaporation and drying out soils faster, making landscapes more flammable. In addition, studies show that persistent atmospheric circulation patterns, including blocking systems and “heat domes,” can prolong extreme heat over southern Europe, increasing the duration and severity of heatwave conditions. 

Here’s where the polar connection matters. The Arctic is warming nearly four times faster than the global average. That narrows the temperature difference between the poles and the equator, which weakens the jet stream – the high-altitude wind band that normally steers weather systems across Europe. This can increase the likelihood of stalled weather patterns over Europe, allowing heatwaves and dry conditions to persist longer than in the past, creating conditions for repeated fire-conducive environments. 

What this means beyond the fire lines 

• Public health: Rising smoke exposure increases risks of respiratory and cardiovascular illness across multiple countries due to unsafe air pollution levels 

• Transport & tourism: Road closures, flight disruptions, and event cancellations are increasing economic losses  

• Ecosystems: Repeated burning is degrading Mediterranean ecosystems and reducing long-term forest resilience  

• Cross-border impacts: Smoke and particulate transport are affecting air quality far beyond fire zones, including urban centres in Western Europe  

• Compounding risk: Burn scars increase the likelihood of future fires by reducing vegetation cover and increasing soil dryness 

What needs to change 

• Strengthen cross-border wildfire coordination and rapid response systems. 

• Expand climate-resilient land management, including firebreaks and controlled vegetation reduction  

• Integrate wildfire risk into urban planning, transport infrastructure, and tourism safety protocols 

What you can do  

• Stay indoors during peak smoke and heat periods; follow local evacuation advisories 

• Use FFP2/N95 masks when air quality is poor due to wildfire smoke  

• Limit physical activity during high heat days  

• Stay informed via official civil protection and air quality alerts
