Firefighters were called two simultaneous grass fires in Croydon as the heatwave continued.
Eight fire engines and around 60 firefighters dealt with a fire on Oaks Road in Croydon. One hectare of woodland was alight. The Brigade was called at 1207 and the fire was under control by 1421. Fire crews from Addington, Biggin Hill, Wallington, Croydon and surrounding fire stations attended the scene.
Another four fire engines also dealt with a grass fire on Chapel View in South Croydon, where around one hectare of woodland and undergrowth was damaged by fire. The Brigade was called at 1220 and the fire was under control by 1430. Fire crews from Purley, Plumstead, Greenwich and Lambeth fire stations attended the scene.
There were no reports of any injuries.
A London Fire Brigade spokesperson said: "The recent hot, dry weather has made the ground extremely dry, which unfortunately means grassland and parks will burn quickly when exposed to even the smallest of sparks.
“Common causes of grass fires include carelessly discarded cigarettes or matches as well as rubbish left lying around such as glass bottles, which can start flames by magnifying the sun’s rays.
“Every one of us can help reduce the risk of fire and keep our communities clean, make sure rubbish is safely thrown away and cigarettes are always properly disposed of.
“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. If you see signs of smouldering grass then call the Brigade and let us know where the fire is.”
