Amber heat health alert in force as temperatures set to soar in UK - and severe weather hits Europe
Temperatures could reach 30C today as the UK braces for four days of hot weather, with an amber heat health alert in force.
The UK Health Security Agency (UKHSA) alert - the second in two weeks - which covers London, the East Midlands, South East, South West and East of England, will last until 6pm on Tuesday.
A yellow heat health alert also covers Yorkshire and The Humber and the West Midlands over the same period.
The previous amber health heat alert was issued for all parts of England on 19 June, the first time it had been used since September 2023.
The UKHSA alerts are designed to warn health and social care workers about the impacts of hot weather on their services, including possible weather-related deaths in those aged 65 or with long-term conditions. They are not public weather warnings.
Europe is also facing severe weather - with wildfires breaking out just south of Athens on Thursday and authorities banning outdoor activity and non-essential travel for building and delivery staff on Friday.
Meanwhile, storms in France and Germany have left at least three people dead and authorities in Spain are warning residents to stay indoors due to hotter-than-normal temperatures.
34C possible on Monday
A heatwave could be possible with the next four days of above-average temperatures, however.
Highs of 34C are possible on Monday - with a 20% chance of beating the hottest June day on record of 35.6C from 1976, according to Sky News weather producer Joanna Robinson.
The likelihood of a record-breaking temperature on Monday could increase over the weekend as the day approaches.
If the temperature does exceed 35.6C it would make it the hottest start to Wimbledon ever - with the world-famous tennis tournament beginning on Monday. The highest temperature for the opening day of the tournament so far came on 25 June 2001, with 29.3C at Kew Gardens.
Heatwave criteria are likely to be met in a few places on Sunday and Monday, mainly across parts of central and eastern England.
A heatwave is recorded when the threshold is met, varying between 25 degrees for most of the UK and 28 degrees for London and the South East, for three consecutive days.
Robinson said there is some uncertainty over how quickly daytime temperatures will start to fall - but it is likely to happen from Tuesday.
A rapid analysis from scientists at World Weather Attribution has found that June heatwaves in the South East - where there would need to be three consecutive days of temperatures above 28C - are about 10 times more likely due to climate change compared with the cooler pre-industrial climate.
'Rise in temperatures over next few days'
Met Office meteorologist Jonathan Vautrey said: "The big talking point at the moment is the rise in temperatures we're going to be seeing over the next few days."
Conditions in Glastonbury, where more than 200,000 festival-goers will be exposed to the heat, are expected to be between 26 and 27 degrees this weekend.
By contrast, northwest England, parts of Northern Ireland, and southern Scotland could see some rain today, and Scotland will see average temperatures for the time of year, but across England it could hit between 29C and 30C in the south east, the forecaster said.
There will also be some clouds and it will be quite blustery, but it will ease on Sunday.
On Sunday, temperatures will pick up, northwestern Scotland may still see rain, but everywhere else will be warmer, with expected highs of 30-31C in the southeast.
There will be a northwest and southeast split on Monday with a chance of it feeling wetter and windier across the northwest, but the heat will remain across central and southern regions.
Temperatures reached highs of 29C in Coningsby, Lincolnshire, on Friday.
It comes after 2023 brought the hottest June on record with heatwaves also seen in June 2017 and June 2020.
Last Saturday was the hottest day of 2025 so far, with a provisional temperature of 33.2C recorded in Charlwood, Surrey.

Week of sweltering US heat – is this the new normal in a warming world?
The list of climate-related disasters in the US was long last week as vast swathes of America sweated under a brutal heatwave. There was a 'mass-casualty event' of fainting high-schoolers in New Jersey as a K-pop concert was cut short in Washington. Young hikers had to be rescued in New Hampshire as tarmac roads bucked and melted in South Dakota and Nebraska. Luckless Amtrak passengers were stuck on a train with no air conditioning in a Baltimore tunnel, while some subway services in New York were suspended. The Trump administration declared a power emergency in the US south-east, and in Georgia the agriculture commissioner advised residents to make sure their animals had water and shade. 'Remember to take care of our friends also,' Tyler Harper said. These incidents – and many more – were the result of the highest temperatures across the northern and middle swath of the US at this early summer date in some cases since the late 19th century. Nearly 130 million people were under extreme heat warnings or heat advisories on Thursday, according to Noaa's Weather Prediction Center, with 282 locations breaking daily heat records this week, with another 121 equalling with previous highs, Noaa data showed. Daily heat records were set in at least 50 cities in the eastern US on Tuesday alone, according to the National Weather Service, with New York City recording its hottest day since 2012, according to Noaa. Climate scientists blamed a rapidly warming Arctic for the heat dome – a consequence that they say is the result of the 'stuck' weather patterns that come from a wavier polar jet stream, which can cause not just heatwaves but also heavy rainfall and floods. A new study, published in the scientific journal Proceedings of the National Academy of Sciences, said found that stalled atmospheric patterns have tripled over the last 70 years. The authors of the study claim that while climate models predict that these patterns would occur more frequently with climate change, their study is the first to demonstrate that it is already happening – and will likely intensify as the planet continues to warm. Climate Central's climate shift index estimates that high temperatures over the past few days were at least five times more likely to occur because of human-caused climate change. Climate Central scientist Zachary Labe told Politico that the early heatwave 'is a stark reminder that climate change is making these dangerous and oppressive heat waves far more likely, affecting millions of people'. 'One of easiest ways to see climate change's impact is in how it's increasing the chance these types of heatwaves will occur,' Labe told Bloomberg. 'By the middle of this century, these types of heat waves will be normal. The extremes will be even higher.' According to the American Medical Association, elevated temperatures nearly 22,000 people died from heat in 14 years between 1999 and 2023. The National Weather Service statistics show heat claiming more lives than any other weather-related event. But heat events are only fatal in the extreme. A broader, general sense of oppression and discomfort was palpable in New York last week, when the extreme hear arrived after a cool spring and gave New Yorkers little time to acclimatize. 'We all know that prolonged heat exposure can have serious effects on your overall health, including mental health, but it can also negatively affect your skin,' said Kim Laudati, chief executive of IT Intelligent Treatment, a skin regeneration business in New York. Prolonged heat exposure due to the skin's moisture-barrier protective function becomes damaged, Lauditi said, leading to water loss within deeper and surface layers of skin, resulting in a state of dehydration. Chronic heat can lead to vasodilation and persistent redness. Inflammation ensues, which can also promote heat-induced erythema, or redness, to the point of creating telangiectasia; commonly known as 'spider veins' and melasma, a skin discoloration. There is also reduced concentration, irritability, and mood swings because the body is diverting resources to regulate body temperature; the impairment of melatonin production, leading to poor sleep. Heat-related damage to the blood-brain barrier can cause lack of focus, confusion, fainting and organ failure. 'With climate change already reshaping how we live, it's more important than ever that we educate ourselves,' Lauditi said. Climate change was on the minds of voters last week in New York's mayoral primary that culminated on the hottest day of heat-dome, when a thermometer at Belvedere Castle in Central Park registered 99 degrees for the first time since July 18, 2012. Democrat mayoral nominee Zohran Mamdani has said that the climate crisis is the central issue of out time and that it isn't separate from the crisis of capitalism, making it a co-traveler with his resonant message about the affordability of life, or lack of it, in the city. Zohran's climate platform is grounded in making the lives of working people better through climate action,' said Denae Ávila-Dickson with the Sunrise Movement, a climate group that endorsed Mamdani. 'He has an important commitment to transforming New York City into a national leader on climate.' 'It's clear to us that the climate crisis has been politicized, but it's not a political issue,' Ávila-Dickson added. 'It's affecting people in every city, in every state, and a lot of times we fee that it affects people in right in rural States, especially because they're not having those same kinds of resources.' In a typical year between 1979 and 2000, the average temperature in the northern hemisphere temperature would break the 21C (69.8F) barrier in July and continue for about five weeks, according to University of Maine's Climate Change Institute. But last year, the hottest on record, the northern hemisphere's average temperature held above 21C from 13 June until 5 September, and data from the Environmental Protection Agency shows that heatwaves have grown longer, more frequent and more intense over the past seven decades. 'If I was to compare this with what happened in the 20th century, it would be very unusual,' said Sonia Seneviratne, a Swiss climate scientist at the Institute for Atmospheric and Climate Science of the ETH Zurich, told the Washington Post.

Heat wave temperatures to hit 30C today as heatwave continues
Temperatures are predicted to hit 30C for the second day in London today as a heatwave continues. The east of England and the Midlands are both forecast to see highs of 28C, according to the Met amber heat health alert was issued for some areas on Friday by the UK Health Security Agency (UKHSA) until 18:00 BST Tuesday, with temperatures set to peak on Monday. This is the second amber alert in two weeks and means weather impacts are "likely to be felt across the whole health service". The head of extreme events and health protection at UKHSA has urged people to check on those who are more vulnerable and take "sensible precautions while enjoying the sun". The alert stretches across London, the East Midlands, South East, South West and East of England.A yellow heat alert, less serious than amber, has also been issued for Yorkshire and Humber as well as the West Midlands. It denotes "significant impacts" for the health and social care Monday, the UKHSA has warned, "Much of the country will see temperatures in the early to mid-30s" (C) at the height of the country's current record high for June rests at 35.6C, set in Southampton's Mayflower Park in 1957 and met again at Camden Square in North London in Farmer, Director of Operations at London Ambulance Service has warned: "It's really, really important to keep hydrated" and to "keep away from alcohol" in the heat. Keeping out of direct sunlight in the middle of the day and taking your medication in a timely manner are also key, Farmer Johnson, wife of former prime minister Boris Johnson, has urged breast-feeding mothers in particular to stay hydrated after she was hospitalised for two nights for severe at Glastonbury festival, which is now in the last of its five days, are expected to reach 27C on Sunday. The hottest year for the festival was 2017, when highs of 30C saw dozens of people being treated by paramedics.

UK heatwave: Why do our cities get so hot?
The temperatures we are experiencing as part of the current heatwave are expected to peak on Monday in the cities of London and may have noticed that temperatures are often much higher in urban areas than in the surrounding is because of something called the urban heat island helps to explain why built-up areas can be several degrees warmer than nearby rural places, during the day and leaves people living in cities more vulnerable to the impacts of climate change. What are urban heat islands? During heatwaves, city centres are on average 4-6C (39-43F) warmer than surrounding areas according to the European Commission Joint Research Centre, extreme cases the difference can be as much as 10C (50F), especially in very calm weather with little wind to mix the air.A key reason for this contrast is the hard, dark-coloured surfaces, like buildings and roads, that dominate urban absorb the Sun's energy rather than reflecting it, meaning they store heat. This is then slowly released into the surrounding air leading to higher temperatures, especially at heat generated by air conditioning units, vehicles - and humans - adds to this even further. In the countryside trees, rivers and lakes provide natural cooling and a source of moisture. Some of the Sun's energy is used in evaporating this moisture which leaves less to heat the land and the air, limiting the temperature tend to have less vegetation and fewer water sources meaning the ground and the air heat up more phenomenon also helps to explain why the very hottest days tend to be after a long spell of dry weather. The less moisture there is to evaporate, the more energy remains to lift temperatures. Is climate change making things worse? Extreme heat can be very uncomfortable and also and heat stroke can occur when temperatures rise, and urban heat island effects can also help to trap pollution leading to poor air change does not cause urban heat islands but because cities tend to be hotter, they are likely to be worst-affected by rising global to the UN, 55% of the world's population live in urban areas. This is projected to increase to 68% by climate change makes heatwaves more frequent and more intense, it will be cities - and their growing populations - that bear the brunt of extreme heat and the significant impacts it can bring. Tackling urban heat Planners in some of the world's major cities are taking measures to mitigate and adapt to the building Singapore, authorities are incorporating open spaces, external around buildings and lighter colours on walls and roofs, as well as increasing the amount of greenery in the half of Singapore is now green space and more than half a million trees have been planted since 2020 - with an eventual target of one million trees by 2030. In Spain, Barcelona has a growing network of more than 400 free climate shelters, external where people can shelter from extreme summer heat as well as from winter offer a maximum temperature of 26C (79F) and must provide comfortable seating and free drinking cities including Paris, Buenos Aires and New York have introduced similar in Phoenix, Arizona, researchers have been trialling lighter-coloured roads and pavements in an attempt to reduce heat in the urban centre.
