Map reveals how hot it has to remain in each part of UK for a heatwave to be declared as temps to surge above 30C
BRITAIN has been blessed with glorious blasts of heat so far in 2025, with temperatures set to soar to 29C in parts of the UK today.
However, despite the sizzling heat, the Met Office has not yet declared a heatwave anywhere in the nation.

Will there be a heatwave in the UK?
The UK's national weather service has said that parts of the UK could "very well be" in a heatwave by the end of the week, but this depends on certain thresholds being met.
For a heatwave to be declared, a location has to record a period of at least three consecutive days where temperatures met of exceeded the heatwave threshold for that location.
Temperature thresholds are different across the UK, with, as shown in the map above, the threshold for much of the north and west being 25C.
In London and the Home Counties, the threshold is higher, at 28 degrees.
Tony Wisson, Deputy Chief Meteorologist at the Met Office said: 'By the beginning of the weekend we could very well be meeting heatwave thresholds in places.
"While the warmest temperatures are likely across London and the east of England, by Saturday heatwave thresholds could be reached across much of the Midlands, low-lying areas bordering the Peak District and even parts of east Wales.'
How long will the heatwave last?
Tan happy Brits will likely be soaking up the sun today, as London is set to see highs of 29C, with residents of Wales basking in balmy 25C heat.
In London - where the threshold is 28C - temperatures could peak at 29C on Thursday and 31C on Friday, before hitting 32C on Saturday.
The hot weather will then spread further north, with Manchester and Newcastle enjoying temperatures into the late 20s by the weekend.
The Met Office said several places were expected to exceed 30C on Saturday, making them the highest temperatures of the year so far.
Tony said: "Over the next few days, settled weather and warm sunshine will allow temperatures to rise day on day.
"Temperatures will then rise further towards the end of the week as winds turn more southerly and even warmer air over continental Europe will be drawn across the UK.
"While the warmest temperatures are likely across London and the east of England, by Saturday heatwave thresholds could be reached across much of the Midlands, low-lying areas bordering the Peak District and even parts of east Wales."
However, high pressure is expected to move away from the UK early next week, meaning that temperatures will fall.
Tony added: 'Temperatures are likely to peak in the low 30s Celsius this weekend before easing sometime early week.
How to stay safe in hot weather
The UK Health Security Agency advised you follow these tips to reduce your risk of dehydration, heat exhaustion and heatstroke:
Keep out of the sun at the hottest time of the day, between 11am and 3pm
If you are going to do a physical activity like exercising or walking the dog, plan to do these during times of the day when it is cooler such as the morning or evening
Keep your home cool by closing windows and curtains in rooms that face the sun
If you go outside, cover up with light clothing, a hat and sunglasses and slather on sun cream
Drink plenty of fluids but limit booze
Know the symptoms of heat exhaustion and heatstroke and what to do if you or someone else has them
Check on family, friends and neighbours who may be at higher risk of becoming unwell, and if you are at higher risk, ask them to do the same for you

"Some forecast models even allow temperatures to rise into the mid 30s of Celsius by Monday.
"While this is feasible, it is considered a lower-likelihood scenario.'
The London Fire Brigade has issued a warning over wildfires before the prolonged spell of hot weather and following one of the driest springs on record.
A drought was declared by the Environment Agency across Yorkshire last week while the North West of England entered drought status last month.
The UK's June temperature record stands at 35.6C, which was set in Southampton in 1976.
Current forecasts suggest the record is unlikely to be broken this time - but it will come close.

Office rights explained: What temperature is too hot to work in?
THE UK is basking in glorious sunshine with temperatures set to peak at over 30 degrees Celsius in parts. The Met Office has said a heatwave is "likely" this weekend with sunshine continuing into next week. But what are your rights when it comes to working during hot weather? We explain everything you need to know below. What rights do I have if it's too hot in the office? There's no minimum or maximum temperature for offices or other places of work currently defined in law. Employers have to make sure conditions are "reasonable" - but that definition is obviously open to interpretation. John Kushnick, legal operations director at National Accident Helpline said: "Temperatures in the workplace are covered by the Workplace (Health, Safety and Welfare) Regulations 1992, which place a legal obligation on employers to provide a 'reasonable' temperature in the workplace. "They suggest that the minimum temperature in a workplace should be at least 16°C, or if the work involves rigorous physical exertion, it can be 13°C. "Unfortunately, there are no laws which specifically state that workers can stop working if the temperature gets too hot or cold." The Health and Safety Executive (HSE) has previously suggested bosses should ensure their workers have access to water and monitor their wellbeing in hot weather. Typical symptoms of heat stress are: An inability to concentrate Muscle cramps Heat rash Severe thirst - a late symptom of heat stress Fainting Heat exhaustion - fatigue, giddiness, nausea, headache, moist skin Heat stroke - hot dry skin, confusion, convulsions and eventual loss of consciousness. This is the most severe disorder and can result in death if not detected at an early stage However, if enough members of staff complain about working conditions, bosses should carry out a risk assessment. The HSE says: 'If a significant number of employees are complaining about thermal discomfort, your employer should carry out a risk assessment, and act on the results of that assessment.' John adds: "If an employee feels uncomfortable, then they should speak to their employer as they are obliged to act reasonably and provide a safe working environment." If you're a vulnerable staff member - including being menopausal or pregnant - you should take this into account when deciding on a plan of action. You may not get to work from home, though. Instead, the business might provide fans, relax dress codes, turn up the air conditioning, or consider other measures to make things more comfortable. What are the temperature recommendations? The Chartered Institute of Building Services Engineers recommends the following temperatures for different working areas: Heavy work in factories: 13°C Light work in factories: 16°C Hospital wards and shops: 18°C Offices and dining rooms: 20°C What are my rights if I need to take public transport? Each transport company sets its own policies - and like with offices, there's no law about temperatures during a heatwave. This can mean that travellers face extremely high temperatures when out and about. For example, in 2018, Londoners complained of 42C temperatures on the Tube. Transport for London however has since said all Tubes will be air-conditioned by 2030. If you are travelling on public transport, make sure you bring a bottle of water with you, and if possible, wear cool, loose, and light clothing. People are sharing their best "air con" hacks to keep cool in the heatwave and all you need is a bottle of water. If you're sat at work wincing in pain at sunburn caught over the weekend, here's five ways to soothe it. Keeping safe in the sun Wear clothes and sunglasses that provide sun protection The NHS website recommends wearing a hat that that shades the face, neck and ears and breathable fabrics that do not let the sunlight through. Drink water Staying hydrated in the warmer weather is also important. Be sure to carry a water bottle with you if you are travelling and taking sips throughout the day. Use suncream According to the NHS webiste, adults should aim to apply around 6 to 8 teaspoons of sunscreen if you're covering your entire body. If sunscreen is applied too thinly, the amount of protection it gives is not as effective If you're worried you might not be applying enough SPF30, you could use a sunscreen with a higher SPF.

Five-week long heatwaves and 46.6C highs as Met Office predicts scorching decade
Our community members are treated to special offers, promotions and adverts from us and our partners. You can check out at any time. More info Heatwaves lasting as long as 39 days are being forecasted for parts of the UK in the coming years. Temperatures soaring above 40C will become more likely, with a possible maximum of 46.6C, as climate change tightens its grip, the Met Office has warned. Its scientists have warned that, in future, two thirds of British summers could be assessed as being in a heatwave, using current classifications. Spells of hot weather in which temperatures exceed 40C could run for four successive days. Analysis by the Met Office, using global models to create a large number of climate outcomes based on the weather in 2023, shows the risk of 40C temperatures in the UK has been rapidly increasing. A study published in Weather Journal shows the chance of temperatures hitting 40C is more than 20 times greater than it was in the 1960s. 'From less than 0.2% in the 1960s, it has increased more than six-fold since the 1980s and almost trebled since 2000,' said researchers. 'With ongoing climate change, it is likely to continue increasing in upcoming years, meaning that the return time for 40°C is expected to shorten further.' Previous estimates of the pace of change are now thought to have been underestimated, they added. Temperatures hit 40C in the UK for the first time on record amid the hot summer of 2022, peaking at 40.3C in Coningsby in Lincolnshire on July 19. It outstripped the previous top temperature of 38.7°C in Cambridge, set just three years earlier, leaving meterologists surprised by the wide margin of escalation. Not so long ago, a low probability of reaching 40C was estimated for the 2020s, with a return time of 100–300 years. Now – based on current conditions – such temperatures are expected to occur once every 24 years. This rate is expected to rise as the climate warms.

There were significant impacts, including wildfires, disruptions to transport and power systems and increased mortality. More than 1,000 excess deaths among older people were recorded around the heatwave's four-day peak, with more than 3,000 heat-related deaths in England over summer 2022. The study's lead author Dr Gillian Kay, senior scientist at the Met Office, said awareness of the warming trend will help preparedness in the health and in other sectors – not just in the decades to come but 'now and in the near term'. She said: 'The chance of exceeding 40C has been rapidly increasing, and it is now over 20 times more likely than it was in the 1960s. Because our climate continues to warm, we can expect the chance to keep rising. "We estimate a 50-50 chance of seeing a 40C day again in the next 12 years. We also found that temperatures several degrees higher than we saw in July 2022 are possible in today's climate.' (Image: Met Office) The summer of 1976 saw 18 days exceed the temperature threshold that defines a heatwave. Based on current projections, future heatwaves are forecasted to last more than a month (39 days). The Met Office study, 'Rapidly increasing chance of record UK summer temperatures', drew its conclusions from data in south east England, where the heatwave threshold is 28C on three successive days. In Wales, the threshold temperature is lower, at 25C, suggesting that longer spells of above-average temperatures can be expected here too. The same model runs also indicated that 63 days each summer (in southeast England) will reach at least 28C, with temperatures hitting 35C on 20 days – four times the current rate.

'Our study finds that in today's climate such conditions could persist for a month or more. These findings highlight the need to prepare and plan for the impacts of rising temperatures now, so we can better protect public health, infrastructure, and the environment from the growing threat of extreme heat.'

Royal Ascot could relax strict dress code as course set to sizzle in 30c heat
The track's official dress code, which include top hat and tails in the Royal Enclosure area, could be relaxed if conditions become too uncomfortable Royal Ascot is set to sizzle as temperatures could soar beyond 30C over the next four days. A yellow heat health alert has been issued for most of England with the mercury predicted to rise as high as 33C by the weekend. Ascot is in the area covered by the Met Office warning which came into force on Wednesday and will remain in place until Sunday evening. A yellow warning is the lowest category of alert behind amber and red on the UK Health Security Agency's (UKHSA) system. With four more days of racing at the royal meeting due to take place on Wednesday, Thursday, Friday and Saturday, officials at Ascot are monitoring developments and have contingencies in place if action is necessary. The track has cooling equipment on hand for horses and is prepared to relax the strict Royal Enclosure dress code of top hat and tails for me if conditions make it necessary. A spokesperson for the track said: "Thoroughbred racehorses are able to run in very hot temperatures, including in countries such as Dubai. To ensure their welfare here at Royal Ascot we provide them with lots of water and ice if necessary. 'This includes a mobile bowser which holds 1,000 litres and can be towed anywhere on track, as well as 800 litres at the horse exit. Additionally, there are three misting fans in the unsaddling enclosure with 3,000 litres of iced water, with buckets, sponges, and scrapers. "We've had days at Royal Ascot over 30C and we have a dedicated team of people to help cool the horses after they've raced." Regarding the dress code, he continued: 'We will take a common-sense approach to these matters, with customer comfort and safety a top priority. This was demonstrated previously when the dress code wasn't enforced following the arrival of the Royal Procession on the Friday in 2022 as temperatures became uncomfortable.'
