Four fire engines and around 25 firefighters were called to reports of grass alight on Imperial Way in Croydon.
Around one hectare of grass was destroyed by fire. There were no reports of any injuries.
The Brigade's 999 Control Officers took 12 calls to the blaze.
A London Fire Brigade spokesperson said: “When the ground is extremely dry, grassland and parks will burn quickly when exposed to even the smallest of sparks.
"If you see a grass fire, don't attempt to put it out yourself as grass fires can travel very quickly and change direction without warning. Call the Brigade and let us know where the fire is."
Brigade top tips on grass fires:
- Avoid having barbecues in parks, public spaces and balconies.
- Clear away bottles, glasses and any broken glass to avoid them magnifying the sun and starting a fire.
- Dispose of smoking materials such as cigarettes safely- don’t drop cigarettes on dry ground and don’t drop them out of car windows, as they may land on dry grass and lead to a fire.
- Disposable barbecues that have been discarded and abandoned can still end up causing a fire as they will continue to retain heat after use – never leave barbecues unattended, they need to be put right out and cooled before being thrown away.
- Be aware that children, animals, balls or anything else may knock over barbecues, increasing the risk of grass fires, especially when in a busy parks or public spaces.
- Explain to children the dangers of playing with and lighting fires.
The Brigade was called at 1437 and the fire was under control by 1611. Fire crews from Croydon, Purley and Wallington fire stations attended the scene.
The cause of the fire is under investigation.
