Tinder-Dry Britain: Why One BBQ Could Start a Major Fire

That brown grass isn't just dead-looking — it may be fuel waiting for a spark.

Across Britain, we have become very familiar with the sight of brown lawns, dusty verges and fields that have changed from lush green to something resembling straw.

It is tempting to think of this simply as a gardening problem.

The lawn looks terrible. The plants need watering. The countryside could do with some rain.

But there is another consequence of prolonged hot, dry weather that deserves much more attention:

fire.

During summer 2026, prolonged warm and dry conditions have repeatedly increased wildfire risk across parts of Britain. The Met Office has highlighted the combination of dry ground, heat and wind as particularly significant because a fire that begins very small can spread surprisingly quickly.

And this is one environmental problem where individual behaviour really does matter.

A discarded cigarette.

A disposable barbecue.

A fire pit.

A garden bonfire.

A car parked on dry grass.

One careless moment can be enough.

Brown Grass Is More Than an Unattractive Lawn

When grass is green, much of the plant contains water.

After weeks without significant rain, the above-ground vegetation dries. What looked like a lawn a few months earlier can effectively become a layer of dry combustible material.

Add a source of heat and oxygen and we have the basic ingredients required for fire.

That does not mean every dry lawn is about to burst into flames. It does mean that activities we would barely think twice about during a wet April deserve considerably more thought during a dry August.

This is perhaps the biggest change of attitude we need.

We need to start looking at exceptionally dry vegetation as potential fuel.

A barbecue sitting beside green damp grass is one situation.

The same barbecue surrounded by dry, straw-coloured vegetation after weeks of hot weather is quite another.

The Disposable BBQ Problem

Disposable barbecues are convenient.

For a few pounds we can take one to a park, beach or picnic area, light it, cook lunch and dispose of it afterwards.

But there are several problems.

The obvious danger is the open heat immediately beneath the barbecue.

There are also hot coals, ash and embers. London Fire Brigade warns that wind can carry smouldering ash and embers from barbecues onto dry grass, and specifically advises people not to use barbecues, including disposable ones, in parks and public spaces.

Then comes another easily overlooked danger.

The barbecue can remain hot long after the sausages have disappeared.

London Fire Brigade has warned people not to take disposable barbecues into parks and open spaces during high-risk conditions, noting that they can retain heat for many hours even after appearing to have been extinguished.

Putting one into a bin while it is still hot simply moves the potential fire somewhere else.

My view is increasingly simple: during exceptionally dry weather, the question should not be, "Where can I safely put my disposable barbecue?"

It should often be:

"Do I actually need the barbecue at all?"

A picnic may not have quite the same theatre as cooking outdoors, but there are days when sandwiches are considerably more sensible than flames.

And some places prohibit barbecues altogether. The New Forest, for example, operates as a no-BBQ and no-fire zone across the relevant managed Forest areas. Always check local restrictions rather than assuming a barbecue is permitted simply because you are outdoors.

Having a BBQ at Home? Position Matters

A barbecue in your own garden does not automatically make it safe.

Think carefully about what surrounds it.

London Fire Brigade advises positioning a barbecue on level ground and well away from things that could catch fire, including fences, sheds, trees and tents. It also recommends keeping water or sand available for emergency use and never leaving a barbecue unattended.

That gives us a useful little pre-BBQ inspection.

Before lighting anything, look around.

Is there dry grass beneath it?

Are there dead leaves nearby?

Is there a wooden fence behind it?

Are there overhanging branches?

Is the garden shed only a metre or two away?

Are children running around?

Could a dog knock it over?

Could a football hit it?

And what is the wind doing?

The safest place in April may not necessarily be the safest place in August.

Don't Forget the Wind

Wind changes everything.

A spark that drops almost vertically on a still evening may travel considerably farther in a breeze.

It can also make a developing vegetation fire much harder to predict and control. Current UK fire-service warnings repeatedly emphasise the additional danger created when very dry vegetation combines with windy conditions.

So before lighting a barbecue or fire pit, do something wonderfully low-tech.

Look at the trees.

Look at the leaves.

Feel the wind.

Ask yourself where sparks would travel.

If the likely answer is towards tinder-dry vegetation, perhaps tonight isn't barbecue night.

Fire Pits Aren't Automatically Safer

Fire pits have become enormously popular.

They can transform a garden in the evening and allow us to sit outside long after the temperature has dropped.

But a contained fire is still a fire.

Wood can crack and send out sparks. Burning material can escape. Wind can carry embers.

During prolonged dry weather, open flames deserve particular caution. Fire services advise avoiding campfires and open fires in countryside and open spaces when wildfire conditions are heightened.

Again, this comes down to judgement.

Something being legal does not necessarily mean doing it tonight is sensible.

Think Twice About the Garden Bonfire

Then there is the traditional garden bonfire.

Perhaps we have been pruning.

Perhaps there is a pile of dead branches.

Perhaps there is dried vegetation we want to dispose of.

On a damp autumn afternoon, that is one situation.

After weeks of hot summer weather, surrounded by yellow grass and dry hedges, it is quite another.

Devon and Somerset Fire and Rescue Service specifically advises people to avoid lighting bonfires during very dry weather.

The pile can wait.

Compost what you can.

Use your council's garden-waste collection or recycling facilities where available.

Or simply leave the job until conditions are safer.

There are remarkably few pieces of garden maintenance so urgent that they justify creating an unnecessary fire risk.

Cigarettes: A Tiny Source of Heat With Potentially Huge Consequences

A cigarette end looks insignificant.

Against a large field, heathland or roadside verge, it seems almost absurd to imagine something so small causing serious damage.

Yet discarded smoking materials remain one of the ignition risks highlighted repeatedly by UK fire services, which urge people to extinguish cigarettes completely and dispose of them safely rather than dropping or throwing them from vehicles.

This is another example of why wildfire prevention is partly about changing our perception of scale.

We naturally imagine that a large fire requires a large ignition source.

It doesn't.

When the fuel is dry enough, small matters.

The Surprising Risk From Your Car

Here is one that many people may never have considered.

You drive into the countryside.

The designated parking spaces are full.

There is a nice dry grassy verge nearby.

So you pull onto it and park.

The problem is underneath the car.

Vehicle exhaust systems become hot. Fire and rescue services warn that hot exhaust systems and catalytic converters can ignite very dry vegetation underneath a parked vehicle.

So during exceptionally dry weather:

Don't park on long, dry grass.

Use surfaced or designated parking areas.

That seemingly harmless shortcut onto a verge isn't worth the risk.

What About Having Water Nearby?

If you are using a barbecue safely at home where conditions and local rules allow, preparation makes sense.

Have water or sand available before you start rather than trying to find it after something has gone wrong. That is specifically recommended in London Fire Brigade's barbecue guidance.

For a normal barbecue, that might mean:

• a bucket of water;

• a connected garden hose nearby;

• or an appropriate supply of sand.

But there is an important distinction.

Having water nearby to deal with a small barbecue problem is sensible.

Trying to fight a developing wildfire yourself is not.

If a Grass Fire Starts, Don't Become the Firefighter

Suppose you see flames spreading through dry grass.

Your first instinct may be to try to stamp them out or find a bucket of water.

That could be a dangerous mistake.

Official advice is very clear: move to a safe place, call 999, provide as accurate a location as possible and do not attempt to tackle a wildfire yourself. Fires can spread rapidly, change direction and continue burning or smouldering in vegetation.

Don't assume somebody else has already phoned.

Don't get closer to obtain a better photograph.

Don't stand downwind filming it for social media.

Get away from vegetation and smoke and call the Fire and Rescue Service.

If you are somewhere remote, giving an accurate location is extremely important. London Fire Brigade notes that what3words can be useful when a conventional street address is unavailable.

Seven Questions Before You Light Anything

During a very dry summer, I think we could all adopt a simple mental checklist:

1. Do I actually need a flame?

Could today's disposable barbecue become a picnic instead?

2. Is there dry vegetation nearby?

Look beyond the immediate metre surrounding you.

3. What is the wind doing?

Think about where sparks and embers could travel.

4. Is the barbecue or fire permitted here?

Local restrictions can vary.

5. Is it stable and well separated from combustible materials?

Think about fences, sheds, trees, tents and decking as well as grass.

6. Do I have water or sand ready?

Prepare before lighting it.

7. Can I guarantee somebody will supervise it until it is completely cold?

If not, don't light it.

This Is Going Green Too

Going green usually makes us think about solar panels, electric cars, recycling, heat pumps and reducing energy use.

But protecting the environment also means not accidentally setting fire to it.

A grass fire can destroy habitat that took years to establish.

It can kill insects, reptiles and small mammals.

It can damage trees and hedgerows.

It can threaten homes.

And every major incident requires firefighters, vehicles, water and considerable resources.

The scale of the problem has already been visible this summer. On 5 August 2026, London Fire Brigade received 1,080 emergency calls in a single day, including 206 calls relating to grass fires.

That makes wildfire prevention far more than an abstract environmental concern.

It is something we can act upon today.

Sometimes the Greenest Action Is Simply Not Lighting the Match

This isn't an argument for cancelling summer.

We should be outside.

We should enjoy our gardens.

We should walk through the countryside.

We should have friends round and eat outdoors.

But we also need to adapt our behaviour to the conditions around us.

A British summer landscape that has been baked dry for weeks isn't behaving like the damp green countryside we may be used to.

So look again at that brown lawn.

Look at the straw-coloured verge.

Look at the dry field beyond the garden fence.

They aren't merely waiting for rain.

They may be waiting for a spark.

And preventing that spark is one environmental action every one of us can take.

Sometimes going green means buying new technology.

Sometimes it means changing our behaviour.

And sometimes it is as simple as deciding:

Not tonight. We'll have a picnic instead.
