Britain bakes in a heatwave: Temperatures could hit record 30C as maps reveal where will be hotter than parts of Greece and Spain
Britons basked in more warm weather today amid forecasts that UK temperatures could hit 30C at the earliest point in the year on record this Thursday.
Sunbathers enjoyed the beautiful conditions in parks, beaches and riversides today, with parts of southern and central England expected to get up to 26C (79F).
The Met Office said warm weather will continue tomorrow, with highs of 27C (81F) in London - before temperatures could rise to 30C (86F) in some places on Thursday.
In comparison, Greece will see 26C (77F) in Corfu, 22C (72F) in Athens and 17C (63F) in Crete; while Spain will get to 22C (72F) in Barcelona and 19C (66F) in Ibiza. It will even be warmer than the Canary Islands, with 25C (77F) in Lanzarote and Tenerife.
Forecasters said the period could officially be deemed a 'heatwave' if the mercury reaches 25C (77F) today, tomorrow and on Thursday in certain parts of the UK.
Conditions are far warmer than normal for this time of year, with late April average temperatures around 12C (54F) for Scotland and 16C (61F) for southern England.
Yesterday was also the UK's hottest day of the year so far with 24.5C (76.1F) recorded at St James's Park in London – although that record could be broken again today. If 27C (81F) is reached by tomorrow, it would be the hottest April weather since 2018.
Unseasonably mild nights are also ahead for parts of the UK, with minimum temperatures not expected to fall below 14C (57F) in the South West tonight.
Last night, several areas of northern Scotland recorded their highest April minimum temperatures on record – including Kinloss in the Highlands at 12.6C (54.7F).
Met Office chief meteorologist Paul Gundersen said: 'It is not particularly unusual to see warm and sunny periods in April where temperatures reach the mid-20s.
'This has occurred as recently as 2018 and 2019, for example. However, it is more unusual to see temperatures reach the high-20s, and if we see 30C (86F) this week, it will be the earliest point in the year in which we have achieved that threshold.'
Nicola Maxey, press officer at the Met Office, said: 'As high pressure continues to dominate the UK weather we will see the temperatures building day on day through the week with Thursday seeing the peak of the heat with 29C (84F) or even a chance we could see 30C (86F).
'Friday temperatures will start to dip across much of the UK as the high pressure starts to pull away.'
The highest recorded April temperature was in 1949, when Camden Square in London recorded 29.4C (84.9F).
For May, the highest temperature recorded was 32.8C (91.0F) on May 22, 1922, also in Camden Square.
There is a possibility the UK could see heatwave conditions this week, if temperatures reached 25C (77F) today, tomorrow and on Thursday, the forecaster said.
According to the Met Office, the definition of a heatwave is three consecutive days of temperatures exceeding the 'heatwave threshold', which varies across the country.
The threshold is 25C (77F) for most of the UK, with slightly higher numbers for the South and East, and rising to 28C (84F) in London.
Warnings were also issued by the weather service over high levels of pollen and ultraviolet (UV) rays.
Prolonged exposure to UV rays, emitted by the sun, can lead to sunburn and an increased risk of skin cancer.
People can protect themselves by wearing at least factor 30 sunscreen, spending regular time in the shade and wearing suitable clothing, according to NHS guidance.
Those who suffer from pollen allergies should try to keep the particles out of their eyes, face and hair by staying indoors if they can, or by wearing a mask and hat when outside, medical charity Allergy UK said.
Will UK technically see a 'heatwave' this week?
The Met Office definition of a heatwave is three consecutive days of temperatures exceeding the 'heatwave threshold', which varies across the country.
The threshold is 25C (77F) for most of the UK, with slightly higher numbers for the South and East, and rising to 28C (84F) in London.
There is a therefore possibility the UK could see heatwave conditions this week, if temperatures reached 25C (77F) today, tomorrow and on Thursday.
They are also advised to shower and wash their hair regularly, and to remove the top layer of clothing when coming indoors.
The London Fire Brigade (LFB) urged caution around open-water swimming after last month saw a 32 per cent increase in water-related incidents compared with the same period last year.
Craig Carter, LFB assistant commissioner for prevention and protection, said: 'Even when the sun is shining, water temperatures can be dangerously cold. Cold water shock can affect anyone, no matter how fit or experienced they are.
'It can lead to water inhalation and, in the worst cases, drowning. Be particularly careful near the water's edge, it's easy to slip and fall unexpectedly.
'And think twice before jumping into open water.'
In the first quarter of 2025, LFB crews responded to 160 water-related incidents, averaging more than 13 per week compared with fewer than 11 a week in 2024, the LFB said.
There may also be an increased risk of wildfires as the warm temperatures follow a spell of dry weather in April and March, the Met Office warned.
Gareth Morrison, Head of Water Safety for the RNLI said: 'With the warm weather forecast this week, we want to remind everyone to stay safe when visiting the coast.
'Whilst the air temperature will be high, water temperature remain dangerously cold. If possible, choose a lifeguarded beach and swim between the red and yellow flags.

'If you get into trouble in the water, Float to Live; tilt your head back with ears submerged and try to relax and control your breathing.
'Use your hands to help you stay afloat and then call for help or swim to safety if you can. It's OK if your legs sink, we all float differently. In any coastal emergency, call 999 and ask for the Coastguard.'
Pet owners were also urged to think about their animals in the hot weather.
Dr Elizabeth Mullineaux, president of the British Veterinary Association, said: 'Like us, animals also struggle when temperatures soar. Each year, vets see pets suffering from heat-related problems and illnesses, such as heatstroke, breathing problems, burnt paw pads and sunburn.
'Remember, be sure your animals have access to fresh drinking water, good ventilation and shade from direct sunlight at all times in the summer.'

Temperatures will start to fall from Friday with 25C (77F) being a likely maximum, although the Met Office said the South East may remain warmer than this for a time.
Mike Childs, Friends Of The Earth head of policy, warned that heatwaves will become 'far more frequent and more intense as climate change takes hold'.
'The UK also needs to go further and faster to cut its emissions,' he said. 'A new climate action plan is due in October, and ministers must seize the enormous opportunities this will bring.
'As well as getting UK climate targets back on track, it will also cut bills, create new jobs, insulate our heat-leaking homes - and put the UK at the forefront of helping to fix our broken planet.'

Northern Lights Wales: Once in a decade display next month
Increasing numbers of displays have been spotted, with more of the country able to take in the spectacular sights. Within the last year the Aurora Borealis has stunned the nation with dazzling light displays being visible as far south as Dorset, Essex, Cambridgeshire and Berkshire. Northern Lights sightings have increased in recent years and the explanation is well known in the science community, the Met Office has said. The aurora is concentrated at the Earth's north and south poles (Image: Owen Humphreys/PA Wire) Krista Hammond, a Manager at the Met Office Space Weather Operations Centre (MOSWOC), said: 'Activity on the sun, and in particular the number of visible sunspots, varies over roughly an 11-year period, known as the solar cycle.' The last solar minimum, which is when the Sun had the lowest frequency of visible sunspots in the solar cycle, occurred in December 2019. This means that the sun's activity is currently increasing, with the next solar maximum expected around July this year. As a result, more of the Sun's electrically charged particles are travelling towards the Earth and getting caught in its magnetic field, thus producing more of the aurora effect. Krista added: 'Over the coming years, as we continue towards the solar maximum, we can expect to see an increase in the frequency of space weather events, with more chances to see the Aurora Borealis over the UK.' What causes the Northern Lights? The Royal Museums Greenwich explained: 'Solar storms on our star's surface give out huge clouds of electrically charged particles. These particles can travel millions of miles, and some may eventually collide with the Earth. 'Most of these particles are deflected away, but some become captured in the Earth's magnetic field, accelerating down towards the north and south poles into the atmosphere. This is why aurora activity is concentrated at the magnetic poles.' Royal Observatory astronomer, Tom Kerss added: 'These particles then slam into atoms and molecules in the Earth's atmosphere and essentially heat them up. 'We call this physical process 'excitation', but it's very much like heating a gas and making it glow.' Can I see the Northern Lights in the UK? The Royal Museums Greenwich said: 'The aurora borealis can be seen in the northern hemisphere, while the aurora australis is found in the southern hemisphere. 'While the best places to see the aurora are concentrated around the polar regions, the aurora borealis can sometimes be seen in the UK. 'The further north you are the more likely you are to see the display – but heightened solar activity has meant that the northern lights have been seen as far south as Cornwall and Brighton. 'The conditions do still need to be right however. Dark and clear nights, preferably with little light pollution, offer the best chance of seeing the aurora.'

Exact time thunderstorms end as more rain to fall in 9 hours than all of April
Millions of Brits will be blighted by thunderstorms ruining their Saturday until this evening, with as much as 40mm of rain expected to fall in some parts of the country Thunderstorms are expected to bring more rain in nine hours today than the UK saw in the whole of April. Met Office forecasters have issued a yellow thunderstorm weather warning for the South East, East Anglia, the Midlands, the South West and southern Wales - lasting until 6pm today. The Met Office warned that between 10mm to 15mm could fall in less than an hour, while some regions could see as much as between 30mm and 40mm. The yellow weather alert will remain in the affected regions until 6pm tonight, with people being warned about potential delays to train and bus services. Some buildings could also be vulnerable to lightning strikes, the Met Office said. In England, the amount of rainfall could be more in a single day than the entirety of April, which saw 28.3mm in total. The rest of Saturday will be "very showery" with heavy rainfall as well as gusty winds and hail. Met Office Chief Meteorologist Dan Suri said: 'Frequent heavy showers and thunderstorms are expected for much of Saturday, before they fade from the west during the mid-to-late afternoon. "It's possible that 10-15mm of rain could fall in less than an hour, while some places could see 30-40mm of rain over several hours from successive showers and thunderstorms. Frequent lightning, hail, and strong, gusty winds are also possible. "A yellow warning for thunderstorms has been issued and covers parts of central and southern England and Wales. While brisk winds ensure that most places in the warning area will be hit by showers, not all places will see thunderstorms. In this case it's difficult to predict where exactly thunderstorms will hit because they are small and fast changing. "One analogy we use to picture the complexity of this forecasting challenge is comparing it to boiling a pan of water and having to guess exactly where and when the bubbles will appear. We know some will, but only in certain places, and that is why thunderstorms are so hard to predict." Thankfully, conditions should be "quieter" and "drier" for most on Sunday. There will be some showers around in the north and east of the country. But for many, clear and sunny spells are expected. Next week, sunshine and showers are expected in the north with plenty of dry weather in the south. The Met Office said Tuesday would see the possibility of a new low-pressure-system potentially pushing another weather front over the UK. Temperatures look set to rise with high 20Cs possible in the southeast on Thursday. The warm air will also bring further risk of thunderstorms by the end of the week.

When will weather change as Scots set for soaring 25C temperatures
A 'Spanish plume' is set to engulf the UK and bring about a 'mini heatwave', following this current period of showers. Scots are expected to experience a searing 'Spanish plume' as a mini-heatwave is predicted to hit the UK later on in June. Scotland is set to see soaring temperatures as high as 25C in this sunny spell, which may begin as early as next week. The sweltering heat plume from Europe is to be widespread for the whole of the UK, possibly extending from the southeast all the way up to the Highlands. It comes after Scotland recorded its sunniest spring on record, which was followed by serious widespread showers that will continue into this weekend (June 7 and 8). A thunderstorm warning has even been issued by the Met Office for parts of southern England and Wales for today, June 7. The forecaster said on their website: "Frequent heavy showers and thunderstorms are expected for much of Saturday before fading from the west during the mid to late afternoon. "10-15 mm of rain could fall in less than an hour, whilst some places could see 30-40 mm of rain over several hours from successive showers and thunderstorms. Frequent lightning, hail and strong, gusty winds will be additional hazards." But this is all set to change as soon as next week, as the 'Spanish scorcher' is expected to land on our shores. According to advanced weather maps on WX Charts, Thursday, June 12 is set to kick off the scorcher, with Scottish temperatures set to soar to a piping 25C in northern parts of the country. The mercury is forecast to range between a reasonable 19C and a searing 24C in the central belt on this day, while the Western Isles can expect cooler temperatures of around 14C. As usual, the south of England is set to see even hotter temperatures over the coming scorcher that are expected to reach a whopping 30C. Weather charts for the week commencing June 16 predict more hot air from Spain, that will sweep across France and into the UK, reports The Mirror. By Thursday June 19 and Friday June 20, the heat maps turn a deep red, indicating yet more high temperatures. Thursday June 19 will bring in further searing temperatures for Scotland, that will reach a peak of 24C in the north of the Highlands, while the central belt will see temperatures hover around 22C. The Met Office 's long-range forecasts show that the weather is expected to be a lot sunnier in the second half of June. Its forecast from June 10-19 states: "Changeable weather across the UK at the start of this period with showers or some longer spells of rain spreading in from the Atlantic. The heaviest and most prolonged rain will probably be across parts of the north and northwest, with the southeast likely driest. "Temperatures are expected to be near normal or slightly above. Into the second half of next week, there is potential for some warm or hot weather to develop, particularly in the south and east, although this may be accompanied by heavy showers and thunderstorms. "Into the middle of June, high pressure may become more dominant. This could bring periods of fine and dry weather, especially in south and temperatures rising above normal, although some thundery outbreaks remain possible."
