Residents of Nethy Bridge, a village in the Cairngorms National Park, were told they could return home on Saturday after a wildfire that burned for 10 days was declared no longer an immediate threat. The fire, which forced the evacuation of around 700 people, was declared a major incident by Police Scotland on Friday 25 July 2026, but that status has now been stood down. First Minister John Swinney said the government and emergency services would continue to treat the blaze “with the utmost seriousness until the last flames are out.”
A wildfire is an uncontrolled fire that burns in forests, grasslands, or other rural areas. In the UK, they are most common in spring and summer, especially during prolonged dry, hot weather. The Cairngorms fire is a textbook example: it started in a national park after weeks of heat and drought, fed by dry vegetation and driven by strong, shifting winds. The smoke drifted as far as Aberdeen, triggering a health advisory for people with asthma or other respiratory conditions.
“Why UK national park wildfires are becoming more frequent and severe due to climate change.”
Wildfires in the UK are not new, but they are becoming more frequent and severe. Scotland’s fire season, traditionally confined to spring, is now stretching well into summer because of climate change, according to fire services. A 2025 study found that the burning of fossil fuels has doubled the chance of wildfires erupting compared with the preindustrial period. While most wildfires are caused by humans – unattended campfires, discarded cigarettes, or arson – the conditions that allow them to spread are increasingly set by a warming climate. Researchers call this “fire weather”: hot, dry spells that evaporate moisture from vegetation, turning forests into tinderboxes.
For UK readers, the growing risk of wildfires means more than just dramatic headlines. Smoke from these fires can cause sore throats, breathing difficulties and worsen conditions like asthma. Evacuations disrupt lives – as seen in Nethy Bridge, where residents complained about a lack of communication and said the major incident declaration came too late. The economic cost is also high: 75 firefighters remained on the ground at Cairngorms on Saturday, and the Scottish government coordinated a multi-agency response. Across the channel, wildfires in France and Spain have already forced 270,000 people to flee, with British holidaymakers caught up in the chaos. The Foreign Office has not yet issued travel warnings, but the situation is being closely monitored.
Q: What causes wildfires in the UK? Most UK wildfires are started by human activity, such as unattended campfires, barbecues, discarded cigarettes, or arson. However, weather conditions play a crucial role: prolonged hot, dry spells dry out vegetation and create “fuel” for fires to spread rapidly.
Q: What is a “major incident” declaration? A major incident is an emergency that causes serious harm, damage, disruption or risk to human life, according to the UK’s emergency services framework. Declaring one triggers a multi-agency response, including police, fire, ambulance and local authorities, and can unlock additional resources.
Q: How can I stay safe during a wildfire? If you live in or are visiting an area at risk, follow local advice: close windows and doors to keep out smoke, avoid the affected area, and be ready to evacuate if told. People with asthma or other lung conditions should keep medication close. Never start a campfire in dry conditions and always extinguish cigarettes properly.
What happens next is uncertain, but the trend is clear. As the UK continues to experience hotter, drier summers – like the heatwaves that have baked Scotland for months before the Cairngorms fire – the risk of similar blazes will grow. Fire services will need to adapt, and the public will need to stay informed. For now, firefighters at Cairngorms maintain a significant operational presence until the last hot spots are extinguished, while residents return to smoke-tainted homes and a landscape forever changed.
