Wildfire burns in Peak District as Britain records hottest June day again and red weather warning is extended

By OLIVIA CHRISTIE, NEWS REPORTER Published: 19:35, 25 June 2026 | Updated: 19:58, 25 June 2026 A wildfire has broken out in the Peak District as Britain is in the grips of an unprecedented heatwave that has seen the country sizzle on its hottest ever June day.  Images show huge flames ravaging Tintwistle Moor, near Glossop in Derbyshire, on Thursday. Plumes of smoke billowed overhead as the fire raged on after first breaking out at around 10pm on Wednesday evening.  Footage captured by the Derby Mountain Rescue Team shows the scale of the blaze, which has now affected 400 sq m of land. Derbyshire Fire and Rescue Service said six fire crews were at the scene today - with helicopters throwing water on the inferno from above.  The UK is currently sweltering under a 'heat dome' - with the mercury reaching as high as 36.7C this afternoon, just one day after Gosport in Hampshire hit 36.1C, breaking the record set in 1976. Temperatures are expected to soar again tomorrow to 38C, or 36C in the shade - as swathes of England and Wales remain under a rare red warning for extreme heat.  Footage captured by the Derby Mountain Rescue Team shows the scale of the blaze, which has now affected 400 sq m of land A helicopter flies above a wildfire as burns near a forest in Glossop near Wood Head Reservoir, Derbyshire Thousands of people cool off in the sea in Bournemouth, Dorset, this afternoon  A helicopter throws water above a wildfire as burns near a forest in Glossop A Derbyshire Fire & Rescue Service spokesperson said: 'Six fire engines supported by a water carrier and welfare unit are now in attendance on Tintwistle Moor. 'This is a significant fire affecting approximately 400 metres squared of moorland and woodland.' The Met Office said it had extended a rare red extreme heat warning for 'population-wide adverse health effects' and a 'danger to life' by another day until tomorrow. South East England will remain under the warning, which was previously issued for yesterday and today. It comes as a swimmer died after going into the sea during a visit to Aberavon beach in Port Talbot, South Wales, at about 4.30pm yesterday. Coastguard personnel performed CPR but the 50-year-old man from nearby Cilfrew died at the scene. Elsewhere a fire engine caught fire in the heatwave while travelling to a crash on the A350 at Charlton Marshall in Dorset at 6.30pm yesterday. The crew from Blandford fire station stopped the vehicle and managed to escape before calling for backup. Two other crews from Wimborne and Sturminster Newton rushed to the scene to tackle the inferno which burnt out the engine's cab – and the fire also spread to the nearby grass verge and telegraph cables before it was eventually put out by 8.30pm.  The blaze caused the engine's tyres and cylinders, including breathing apparatus sets, to explode. Last night was also the UK's warmest June night ever after overnight temperatures in Cardiff failed to drop below 23.5C, beating the previous record of 22.7C in 1976.

London Ambulance Service responded to 642 category one calls yesterday – the highest number of life-threatening emergencies in its history. Category one calls include the most serious, life-threatening injuries and illnesses such as cardiac arrests and patients who are not breathing. Chief executive Jason Killens KAM said: 'We have seen the highest number of life-threatening emergencies in our history, driven by the extreme heat across London. 'Our crews are working very hard in challenging conditions to care for patients and I would like to take this opportunity to thank all our people for their incredible hard work. Please help them to help you by taking care of yourself and others – stay out of the sun and keep hydrated.' It was the fifth busiest day in the service's history, with 7,900 calls in total and ambulance crews responding to nearly 3,600 patients in a single day. The comments below have not been moderated.
