Fire chiefs warn UK’s third heatwave heightens wildfire risk

The National Fire Chiefs Council (NFCC) is urging people to take extra care outdoors as the UK experiences its third heatwave since late May, increasing the risk of fast-spreading wildfires across parts of the country. 

Temperatures are forecast to exceed 30°C in many areas this week, with some locations expected to reach around 34°C. While this latest heatwave is not forecast to reach the extreme temperatures experienced in late June, it is expected to last longer. Prolonged periods of warm, dry weather allow vegetation to dry out, making it easier for fires to start and spread. 

Fire and rescue services in England and Wales responded to 342 wildfires recorded between 1 January and 6 July 2026, according to National Resilience data, compared with 639 during the same period last year. 

While overall wildfire activity remains lower than at the same point last year, prolonged hot weather is causing vegetation to become increasingly dry. When both the days and nights remain warm and dry, grass, crops, heathland and woodland are less able to regain moisture, making it easier for fires to start and spread rapidly. If these conditions persist, the risk of larger, faster-moving and more challenging wildfire incidents is expected to increase in the coming days and weeks. 

Fire and rescue services have responded to a number of wildfires across southern and eastern England in recent weeks, where prolonged hot, dry weather has left vegetation particularly susceptible to fire. 

Many wildfires are caused by everyday human activity, and the current conditions mean even a small ignition source can quickly develop into a fast-moving fire. Simple actions such as disposing of cigarettes safely, avoiding the use of disposable barbecues and taking litter home can all help prevent fires from starting. 

With crops now dried and harvesting under way in many parts of the country, the current conditions are also increasing the risk of fires during agricultural operations. Farmers and contractors are encouraged to take extra care while operating machinery and to follow seasonal fire safety guidance. 

Fire chiefs are also urging people not to underestimate the dangers associated with inland water during the current spell of hot weather. 

With the summer holidays beginning in some parts of the UK, fire chiefs are urging people to think twice before cooling off in rivers, lakes, reservoirs, canals and quarries. While air temperatures may be high, the water can remain dangerously cold and entering it unexpectedly can trigger cold water shock. Hidden hazards, including strong currents, sudden changes in depth and submerged objects, can also present a serious risk. 

Dave Swallow, National Fire Chiefs Council Wildfire Deputy Lead and Lead Tactical Advisor, said: 

“Hot, dry weather can significantly increase wildfire risk, but most wildfires start because something provides the spark. Whether it is a disposable barbecue left behind, a discarded cigarette or even a glass bottle left in the sunshine, we all have a role to play in preventing them.

“Summer should be a time for people to enjoy the outdoors, but it’s important not to underestimate the risks. Every year we see devastating wildfires and tragic drownings in inland water.

“As more schools break up for the summer holiday, we’re asking people to enjoy the warmer weather safely, look out for one another and take simple steps to help prevent avoidable tragedies.” 

Wildfires Public Safety Advice: 

• Avoid using disposable barbecues in open countryside, parks, and moorland areas. 

• Do not discard cigarettes, matches, or glass bottles, as they can ignite dry vegetation and crops. 

• Follow local authority guidance on fire risks and restrictions. 

• Report any signs of fire immediately by calling 999 and asking for the Fire and Rescue Service. 

• If you notice any suspicious behaviour or see someone intentionally starting a fire, contact the Police on 101 or report the information anonymously to Crimestoppers on 0800 555 111. 

• If there is a fire, call 999 immediately. 

Water Safety Public Safety Advice: 

• Speak to young people about the dangers of open water. 

• Swim in supervised locations. 

• Do not jump into water to cool off. 

• Never enter the water to attempt a rescue – instead call 999 immediately. 

• If spending time in, on or around water, install location apps such as what3 words so if an incident should happen emergency services know where you are. 

• Do not enter the water if you have been drinking alcohol. 

• Make sure you know how to help yourself and other people in the event of a water-related emergency. 

If you see someone else in trouble in the water this summer, remember Phone, Float, Throw: 

• Phone 999 to get help. 

• Tell the struggling person to float on their back. 

• Throw them something that floats. 

If you find yourself in trouble in the water, Float to Live by: 

• Tilting your head back with ears submerged. 

• Relaxing – to try to control your breathing. 

• Moving your hands to help stay afloat. 

• Once over the initial shock, calling for help or swimming to safety.
