The Met Office forecast for Friday to Sunday states: "Largely settled with spells of strong sunshine, hazy at times. Chance of isolated showers, perhaps thundery. Feeling very warm and humid despite a fresh southerly breeze. Very high pollen levels."
The Met Office definition for a heatwave in the UK is: "A UK heatwave threshold is met when a location records a period of at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold.
"The threshold varies by UK county.

Exact date Scotland to be hit with ‘worst day of the year for hay fever'
Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) HAY FEVER sufferers have been warned that Scotland is set to be hit with the 'worst day of the year' for pollen count in the coming days. Scots are set to bask in scorching 28C temperatures this week as a plume of air from Africa sweeps across the country. Sign up for Scottish Sun newsletter Sign up 4 Scots have been warned that the 'worst day of the year for hay fever' will hit this week Credit: Getty 4 Most of the country will experience 'very high' levels in days Credit: MET OFFICE 4 It comes as temperatures are set to soar as a plume of air from Africa sweeps across Scotland Credit: Andrew Barr 4 And weather maps show that some areas could see highs of 28C Weather maps from WXCharts show that the mercury could climb to its highest levels since summer 2023 as the warmest spell of 2025 heads our way. It comes as air makes its way from North Africa and drifts northwards later this week. The mercury is expected to reach the low to mid-20s by Friday across the country, and STV weatherman Sean revealed that highs of 28C "aren't out of the question". But the warmer weather will also mean that the pollen count will soar at the tail end of this week, leading up to the warmer days. The higher temperatures allow birch trees to offload pollen into the air - which will keep people sneezing for several days. Birch is the main pollen type across Scotland, with ash too in the southern and central regions. With warm, dry sunny weather returning for much of Scotland, this is not good news for hay fever sufferers Max Wiseberg Many hay fever sufferers start to experience symptoms when the count reaches 'medium'. Pollen levels have remained 'medium' in all regions across Scotland over recent weeks. But Friday will see 'high' and 'very high' levels across almost the whole country In fact, it is expected to be so severe that experts have said it is "forecast to be the worst day of the year so far for pollen levels in Scotland". Woman missed her brother's wedding because of 'life-ruining' hay fever symptoms Dumfries, Galloway, Lothian and the Borders had moderate to high levels at the beginning of the week, but this will shoot up to 'very high' levels on Friday and Saturday. Central, Tayside and Fife will follow the same pattern, as well as the Grampian areas. Strathclyde areas and locations in the Highlands will see levels rise from 'moderate' today and tomorrow to 'high' on Friday and Saturday. The only places that will still remain at a 'moderate' level are the Orkney and Shetland Islands. Allergens expert Max Wiseberg says: 'With warm, dry sunny weather returning for much of Scotland, this is not good news for hay fever sufferers as pollen counts are rising across the country. "Friday is forecast to be the worst day of the year so far for pollen levels in Scotland, with the first very high counts of the year across southern, central and north east Scotland "As a general guide, the pollen count tends to be lower on rainy days and higher when it's hot and sunny. June and July are peak hay fever season when grass pollen is at its highest. Friday is forecast to be the worst day of the year so far for pollen levels in Scotland, with the first very high counts of the year across southern, central and north east Scotland Max Wiseberg "Hay fever is a result of our immune system's overreaction to innocuous allergens such as pollen. The body's reaction to pollen is to produce histamines. "Normal amounts of histamines in your brain are good – they keep you alert, attentive and awake. "But, when there are too many in your body, they produce the various symptoms common to hay fever sufferers including sneezing, a runny nose, nasal congestion, itchy eyes, watery eyes, streaming eyes, swollen eyes, itchy nose and throat.' It's estimated that half the British population suffer from hay fever symptoms, according to Allergy UK. Many are plagued by symptoms of hay fever every summer - from itchy eyes, a constant runny nose, and headaches to irritating sneezes and a sore throat. But for people with respiratory conditions, like asthma, high pollen levels can be fatal. Asthma + Lung UK's research suggests pollen is a trigger for 47 per cent of people with asthma and 27 per cent of those who have chronic obstructive pulmonary disease (also known as COPD). This can cause symptoms like coughing, wheezing, a tight chest and breathlessness to flare up. Max, who is also the creator of HayMax allergen barrier balms, has advised hay fever sufferers what measures and precautions to take to help reduce the effects of the pollen. He explained: "As with all allergies, avoidance is key. If you are allergic to wheat, you avoid wheat, and it's the same with grass pollen. Only it's a bit trickier as pollen is in the air we breathe. "So begin with an organic allergen barrier balm to help stop pollen getting in your body. If less gets in, there's less for your body to deal with and less for it to react to. "Organic allergen barrier balms, such as HayMax which has been proven to trap over one third of pollen, are applied around the nostrils and bones of the eyes to trap pollen. 'Next, you can reduce the amount of pollen in and around your home. Keep windows and doors closed to keep pollen out. "Take off your shoes when you return home so you don't tread pollen around. Washing your face, or better still, taking a shower and changing your clothes, on returning home, will get rid of pollen from your body and the clothes you are wearing. 'Ensure that you vacuum floors and carpets regularly, as well as fabrics and upholstery such as curtains and sofas. "And damp dust surfaces – damp dusting helps stop pollen being dispersed back into the air. If you have a pet, make sure you keep it clean and well-groomed to remove the pollen that collects in its fur when it's outdoors." He added: 'Wearing wraparound sunglasses when outdoors will help stop pollen getting in your eyes and a hat, cap or other head covering will help prevent it getting trapped in your hair. 'And of course there are many remedies, treatments and natural products available that help deal with the symptoms once they occur. "Antihistamine tablets work by counteracting the affects of the histamines. Some are available over the counter from pharmacies, whilst others are available only on prescription. "Natural antihistamines are also available, such as quercetin and butterbur. Antihistamine nasal sprays can quickly ease itching, sneezing and watering but are generally only proof against mild symptoms. "Steroid nasal sprays and drops reduce inflammation in the nose; they work best for clearing nasal symptoms – itching, sneezing, watering and congestion – and sprays sometimes clear eye symptoms too. Eye drops may help reduce itchy, watering, swollen eyes. 'And if one product doesn't work try combining treatments – in other words create your own 'Hay Fever First Aid Kit'. "My recommendation is an organic allergen barrier balm, one (and only one) antihistamine, one (and only one) steroid nasal spray, eye drops and one or more natural remedies.'

UK now 20 times more likely to see a 40°C summer
Heatwave-level hot weather will be here for a while – and we might even see temperatures pass 40°C this summer, a UK forecaster has warned. A UK heatwave is expected to be officially declared by this weekend, with temperatures reaching over 30°C tomorrow and sticking around until next week, before another burst of hot weather likely at the end of the month. While many will enjoy the chance of sunning themselves, hotter weather, for example heatwaves, are part of a concerning trend. The UK is now over 20 times more likely to see 40°C heat than it was in the 1960s, the Met Office warned today. Jim Dale, a forecaster who founded British Weather Services, told Metro the rising risk of heatwaves is obvious just from the weather so far in 2025. The driest spring on record, with drought conditions already seen in some areas, has given way to a sunny start to summer that shows no sign of easing. 'We may well see 40°C again before we get to the end of the month,' he said, with the caveat that it's still far enough away for weather models to have a wide margin of error. Dr Gillian Kay, lead author of a Met Office study into heatwaves, said: 'Because our climate continues to warm, we can expect the chance [of 40°C heat] to keep rising. 'We estimate a 50-50 chance of seeing a 40°C 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.' She warned that the UK must 'prepare for even higher heat extremes in the near future'. When UK temperatures went over 40° for the first time that year, it was seen as a shocking outlier. People camped out wherever they could find air conditioning, as London's fire brigade had its busiest day since World War Two. But this type of heatwave may be something we UK residents have to get used to, with models showing the likelihood is shooting up. Dr Nick Dunstone, Met Office Science Fellow and study co-author, said: 'The well-known hot summer of 1976 had more than a fortnight above 28°C, which is a key heatwave threshold in southeast England. 'Our study finds that in today's climate such conditions could persist for a month or more.' If you thought the current UK heatwave was sweltering, there is worse to come, that might even have you looking at flights to Finland. The US National Weather Service's GFS weather model shows another blast of hot air coming our way at the end of June. Mr Dale said it's not normal to be having such hot weather so early on: 'June isn't the hottest month of the year – it never is. July and August are.' He said dry conditions early in the year have made hot conditions more likely. Warmer weather has led to the North Sea, Irish Sea and English Channel being warmer too, meaning when wind blows over the water it has less of a cooling effect. Mr Dale pointed out that other countries have also been experiencing record heat. Temperatures were expected to be over 40°C in southern Spain today, and some stations recorded over 42°C last week. More Trending The Middle East, Asia, and North Africa are all 'going through their June records, if not all time records,' Mr Dale said. 'We're surrounded by all this heat, so it was almost inevitable we would get into an airstream that would deliver the same for us. Hey presto, it's doing that now and will do so for the next four or five days.' The reason for the increased heat is 'climate change, without a shadow of a doubt,' he said. 'It's what is written on the can of climate change: swapping from wet times in winter, to dry times in summer, and droughts etc.' Get in touch with our news team by emailing us at webnews@ For more stories like this, check our news page.

Why having HOT drink cools you down in warm weather as scientists reveal best shower temperature for summer heat too
IT MIGHT sound bizarre, but reaching for a hot drink as temperatures soar may actually cool you down faster than a glass of icy water. And a cold shower might not be the best temperature to beat the heat, either. 2 2 Met Office officials expect this week's sizzling weather to continue over the weekend, with heatwave conditions "likely". Forecasters predict that those living in the East of England will likely see the warmest weather this week, with temperatures as high as 29C in London. Sun-seekers will be sweating more than usual this week - when it is important to stay hydrated and replenish the minerals we lose when we sweat. On a very hot day - like high 30s - people sweat an average of 3-4 litres per hour and up to 10 litres a day, according to research from the University of Reading. The combined amount is the same as 40 cups of tea, researchers wrote. But while replenishing the lost liquid, researchers suggest choosing a hot drink over a cold one. "For a short amount of time, hot drinks raise your core body temperature," researchers explained. "But it induces sweating, which then lowers your temperature." While cold and ice drinks do cool you down too, it's thought "hot drinks might be slightly more effective than cold". Researchers also busted the myth that a cold shower is the most effective way to cool down. Ireland to sizzle in 24C heat as heatwave arrives and Met Eireann reveal hottest areas Although research shows that putting your feet in cold water is a good way to reduce core body temperature - a lukewarm shower is a better option. "Having a lukewarm shower or bath will cool you down faster," researchers wrote. "Don't be tempted to soak in freezing cold water as cold shock can be dangerous." You're putting your fan in the wrong place WITH the weather getting warmer, you might find yourself bringing the electric fan out of storage. British summers can be particularly gruelling, with houses designed to store heat rather than release it. For the best fan placement, you want to find your Goldilocks Zone - the area where you can enjoy the most amount of cool air. Avoid placing the fan up high. While you might think this will tackle the hot air closer to the ceiling, it's actually better placed lower to the ground. This way, the fan can pick up the cooler air that lingers closer to the floor and push it around the room. You can also adjust your fan so it faces the wall opposite from where you are sat - this will drive the air to the surface. Cool air will bounce off the wall, mixing with the rest of the air and bring the overall temperature of the room down.
