A rare amber warning for extreme heat has been issued by the Met Office as a fifth heatwave looms with the risk of temperatures reaching 38C.
The forecaster warned there was a risk of travel delays, adverse health effects and potential power cuts, with the warning covering large parts of England from 9am to midnight on Thursday.
Amber heat health alerts are already in place across large parts of England and Wales, with highs of 29C in Cardiff, 28C in Manchester and 25C in London forecasted for Tuesday.
Meanwhile, firefighters are working “tirelessly” to contain a fire in the New Forest which has entered its third day, which is currently impacting an area as wide as 140 football fields.
Some 45 million people have been plunged into drought conditions as dry and hot weather continues, with the National Drought Group determining that 71.3 per cent of England is now experiencing a flash drought.
England and Wales recorded their driest July in records dating back to 1836, with 19 counties of England seeing no rain for the entire month, provisional statistics have shown.

Historic gardens, parks and cemeteries under threat from climate change
12:30 , Joe MiddletonThe UK’s treasured historic green spaces are under increasing threat from climate extremes, a report warns.
The National Lottery Heritage Fund and Historic England warn that historic parks, gardens and cemeteries across the country are vulnerable to damage from harsher, more widespread drought, intense rainfall, more severe storms and pests which can thrive in warmer conditions.
These impacts, driven by climate change – which is mostly caused by burning fossil fuels for power plants, cars, heating and industry – are affecting all aspects of these heritage landscapes, from trees and plant collections to paths, terraces and lakes.
The report says historic parks and gardens, including Chiswick House and Gardens, Kew and the Royal Parks, in London, and Princes Street Gardens in Edinburgh, employ more than 32,000 people and contribute £2.9 billion to the UK economy each year from international visitors alone.
But they are already being hit by increasingly extreme weather caused by climate change, with paths and drainage systems not fit for current conditions, trees lost to drought and high winds, and potential loss of entire groups of plants to diseases affecting box, ash, sweet chestnut and oak.

Watch: Britain’s pothole problem could get even worse
12:00 , Joe MiddletonPeople urged to check in on elderly neighbours and relatives
11:48 , Holly EvansThere are warnings older people are more at risk from the extreme heat, with Caroline Abrahams, Age UK’s charity director, saying that as people age, their bodies find it harder to adapt to extremes of heat and cold.
“Even younger and otherwise healthy people can feel the effects of very hot weather, but with temperatures forecast to reach up to 36°C in some areas, the risks can be much greater for older people,” she said.
She said most homes in the UK were not designed to cope with extreme heat, so it was important to keep them as cool as possible, keeping curtains and windows closed during the hottest part of the day and opening windows overnight when temperatures fall.
She urged people to check in on older neighbours, friends and relatives to see if they need support such as picking up the shopping or lending them a fan.
She said: “The increasing frequency of heatwaves, alongside droughts, wildfires and hosepipe bans, shows how important it is that we do more to protect those most at risk as climate change continues to bring more extreme weather.”
High temperatures could cause 'adverse health effects'
11:19 , Holly EvansThursday’s high temperatures could have a negative impact on Brits, the Met Office have warned, with people urged to avoid the sun at the hottest part of the day.
“Adverse health effects are likely to be experienced by those vulnerable to extreme heat,” a spokesperson for the forecaster said.
“The wider population is likely to experience some adverse health effects including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat-related illnesses
“Some changes in working practices and daily routines likely to be required.
“Some heat sensitive systems and equipment may fail, with the potential for some power cuts and the loss of other services to some homes and businesses.
“More people are likely to visit coastal areas, lakes and rivers leading to an increased risk of water safety incidents.
“Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays.”
Breaking: Amber warning for extreme heat issued
10:59 , Holly EvansThe Met Office has issued an amber extreme heat warning for large parts of England on Thursday.
The warning will be in place from 9am to midnight with warnings that temperatures could reach as high as 38C.
It covers London, most of the Midlands, including Leicester and Birmingham, and parts of the South East, Yorkshire & the Humber and the East of England.
Met Office warn of 'widespread heatwave'
10:21 , Holly EvansThe Met Office has warned that there will be little let-up on the heat this week, with a heatwave predicted in the coming days.
Temperatures could reach as high as 36C on Thursday, as amber heat health alerts are issued for large swathes of England and Wales.
Met Office Chief Forecaster Jason Kelly said: “Heat will gradually build this week, with temperatures reaching into the mid-30s Celsius in what will be a fairly widespread heatwave for England and Wales.
“The driver for this week’s heat is high pressure, this becoming dominant over the next day or so, bringing plenty of sunshine and allowing temperatures to build day-by-day.
“Southerly or southeasterly winds will also tap into the hot conditions over Europe, meaning we’re looking at further notable heat for many this week, likely peaking on Thursday.”
New Forest fire likely to continue for 'some time to come'
10:00 , Holly EvansA deputy chief fire officer said firefighters are likely to be battling the New Forest fire “for some time to come”.
Shantha Dickinson, of Hampshire & Isle of Wight Fire and Rescue Service, said it had been a “very challenging few months so far for wildfires”, adding that tackling them was “incredibly resource-intensive”.
Discussing the New Forest fire, Ms Dickinson told BBC Radio 4’s Today programme: “Our firefighters and all of our emergency responders have been working in incredibly difficult conditions actually for the last 36 hours since the event started on Sunday evening due to a van fire.
“And we’re likely to be there for some time to come.”
She added: “We’re battling hard to get it under control.
“It currently covers an area of about a kilometre square. So just to put that into perspective, that’s about 140 football fields, so rolling heathland of beautiful countryside.”
When will the heat ease?
09:39 , Holly EvansWith a fifth heatwave fast approaching, many are questioning how much longer will the high temperatures last.
Met Office Deputy Chief Forecaster David Oliver said: “While Thursday will be the peak of the heat this week, some warmth will remain in the south and southeast on Friday, before easing more widely on Saturday as cooler air spreads south from the northwest.”
The forecaster added that high pressure is likely to retain some influence over the weather in the south of the UK later in the weekend but may begin to weaken into the start of next week.
Details are uncertain, but this may allow showers or some longer spells of rain to spread across parts of the UK for a time.
Mapped: Where drought has been declared in the UK
09:14 , Holly EvansAlmost three-quarters of England is now suffering from drought as weather conditions continue to worsen into August, piling pressure onto vital industries.
Officials from the National Drought Group assessed on Monday that 71.3 per cent of the country is now in drought, with the addition of the East Midlands, Lincolnshire and Northamptonshire, Kent and East Sussex, and Solent and the South Downs bringing the number of people affected up to 45 million nationwide.
The North East and Yorkshire have moved to prolonged dry weather – the stage before drought – with nowhere now deemed in normal status, and 27 million people are currently living under restrictions on water use, they said.

Firefighters work ‘tirelessly’ to contain New Forest fire
08:01 , Holly EvansFirefighters are beginning a third day of tackling a fire in the New Forest which they say they are “managing to contain” after working “tirelessly” through the night.
Hampshire Fire and Rescue Service, assisted by neighbouring services, initially scrambled 26 fire engines and four water carriers to the eastbound A31 after receiving 160 emergency calls reporting a van had caught fire on Sunday evening.
The fire service said the blaze spread from the vehicle to the central reservation before progressing into nearby heathland in a south-easterly direction towards Backley Bottom, and is in a “challenging rural location”.
An update released on Tuesday by the fire service said that a change in wind direction had “provided a challenge” overnight but it was managing to prevent “spread and escalation” with the help of a police drone to prioritise hotspots and flare-ups.
A total of seven fire engines with water carriers and off-road vehicles were involved in the operation overnight which continued to use water being pumped through miles of pipes laid from a nearby lake as part of a high volume pump (HVP) system.
And the A31 – the main route through the New Forest – remains closed, with National Highways saying that repairs needed to “significant” damage to the road surface, safety barriers and boundary fencing can only start once the fire is safely under control.
Amber heat health alerts come into force across England and Wales
07:40 , Holly EvansHeat health alerts are to come into force as the UK braces for the fifth heatwave of the year, with almost three-quarters of England in drought.
On Tuesday, highs of 29C in Cardiff, 28C in Manchester and 25C in London are forecast before temperatures soar to the mid-30s in some areas on Thursday, according to the Met Office.
From 9am on Tuesday, heat health alerts issued by the UK Health Security Agency (UKHSA) are in place across England until Friday evening.
Officials have urged people to take simple steps to stay safe, such as drinking plenty of water, checking on vulnerable friends and family, and avoiding the sun at the hottest part of the day.
Amber heat health alerts have been issued for most of England including the Midlands, South East, North West and South West, while a yellow alert will be in force for the North East.

Invest in climate defence rather than heed Trump on military spend – Polanski
04:30 , Dan HaygarthThe UK should be investing money in defending the country against the climate crisis rather than listening to Donald Trump on security spending, Zack Polanski has said.
The Green Party leader on Saturday reiterated his view that the climate crisis is “the biggest threat to our national security since the Second World War”.
Appearing at Iain Dale All Talk at the Edinburgh Fringe, he was asked by an audience member whether he and his party agree with increasing defence spending to 3% of GDP when there are “so many competing environmental needs.”
Mr Polanski said that if defence spending includes money for climate adaptation such as dealing with floods and wildfires then we “clearly need to up our spending”.
He suggested that was more important than listening to US President Donald Trump, who has called for Nato allies to shoulder more of the burden of European defence.
Mr Polanski said: “If we’re talking about spending 3.5 per cent of our GDP on military spending to please Donald Trump, then I think there’s an absolute incoherency in that.
“We’re already, I think, one of the fifth biggest spenders on military capacity, and actually, I think we need to look at defence as a much more holistic issue.
“I said this week, and I really believe, that the climate crisis is the biggest threat to our national security since the Second World War.
“It’s not some distant threat – it’s right here, right now. We’ve had wildfires not far away from here, where we’re talking in Edinburgh, and we know that what’s happening right now is not the new normal.
“This is the beginning of what will be the least extreme temperatures and least extreme weather in our lifetimes.
“It is going to get worse and worse and worse. And in many ways, it’s a grim message.
“We can’t stop some of that breakdown, what we can do, though, and it’s important that people hear this, is we can stop total breakdown, and that feels beyond important to do, and that’s where we should be investing right now, not on listening to what Donald Trump says or creating arbitrary numbers of GDP.”

03:30 , Dan HaygarthRecap: Almost three-quarters of England in drought as conditions worsen in dry August
02:30 , Dan HaygarthAlmost three-quarters of England is in “flash drought” as a dry start to August follows the country’s driest July on record, the Environment Agency (EA) has said.
The East Midlands, Lincolnshire and Northamptonshire, Kent and East Sussex, and Solent and the South Downs have become the latest areas to move into drought.
The announcement came after a meeting of officials, water companies and farming leaders under the National Drought Group, which warned that all regions of the country are experiencing pressure on their water resources, with impacts on agriculture, public water supplies and the environment.
Last week, the EA announced that half of England had plunged into flash drought – one which develops very quickly because of a combination of very low rainfall and high temperatures – and the latest announcement means 71.3 per cent of the country is in drought.
The North East and Yorkshire have moved to “prolonged dry weather” status, the stage before drought, and nowhere in England is in “normal” status, the EA said.
The latest drought warnings came as parts of the UK braced for the fifth heatwave of the summer, with temperatures expected to climb into the mid 30Cs later in the week, peaking at 36C on Thursday.

'Water resilience cannot be treated as a seasonal issue'
Monday 10 August 2026 23:30 , Dan HaygarthFran Barnes, chief executive of the Horticultural Trades Association (HTA), said: “With almost three-quarters of England in ‘flash drought’ and all of Wales now officially in drought, numerous water restrictions and Temporary Use Bans (TUBS) across the UK, and data showing that last month was officially the driest July on record, the pressure on our water resources couldn’t be clearer.
“The solution to the UK’s water challenges lies not just in the amount of rainfall, but in how effectively we capture, store, and manage it. Today we reiterated the need for the UK to take action and implement a long-term water resilience strategy that addresses the realities of a changing climate.
“The current conditions are having a huge impact on our 1,400 members – garden retailers, growers, landscapers, designers, suppliers and manufacturers – despite our sector investing heavily in becoming more water efficient. Growers increasingly capture and recycle rainwater, retailers and landscapers promote drought-tolerant planting and more effective watering, including water butts and efficient irrigation systems suitable for gardeners, not just professional growers. We set out these needs again today at the National Drought Group meeting.
“Our climate may be changing, but our message remains clear: water resilience cannot be treated as a seasonal issue.

Monday 10 August 2026 22:30 , Daniel HaygarthSwimming pools and car washes are among the UK businesses that could be hit by a water ban as providers look to conserve resources amid drought conditions and an upcoming fifth heatwave.
Southern Water has applied to the government for permission to issue a “non-essential use ban” in Hampshire and the Isle of Wight. If granted and put into action, the policy would prevent businesses from activities like washing cars with hosepipes and filling private swimming pools.
It comes as almost three-quarters of England and all of Wales have been plunged into drought.

She said the Government was working to make it easier for farmers to build more onsite irrigation reservoirs – something farming leaders have been calling for – and was delivering “long-term change” in the water industry to reduce leaks and deliver nine new reservoirs.
“As we move through this period of drought, I expect water companies to take every available step to minimise leakage and support customers in using water wisely”, she said as she thanked people for abiding by hosepipe bans.
