The UK experiences record-breaking temperatures, with highs reaching 35C for the eighth consecutive day, as heatwave conditions persist into next week.
New Delhi, India Jul 10, 2026 ALN: The UK is set to bake in another day of 35C highs, with temperatures expected to remain at heatwave level until the end of next week.
On Thursday, temperatures exceeded 34C for the eighth day this year, breaking the previous record of seven days over this peak, set in 1976 and 2020. This prolonged period of extreme heat is indicative of a broader trend observed in recent years, where climate change has led to an increase in the frequency and intensity of heatwaves across Europe, including the UK.
The duration of the year's third heatwave, which began earlier this week, has been striking and could last into next week, before cooler, more unsettled weather is forecast to arrive. Meteorologists have noted that this heatwave is particularly notable not just for its intensity but also for its timing, occurring in July when the UK typically experiences its warmest weather.
However, parts of the UK could see some respite over the weekend when a north-easterly breeze on Saturday is expected to pull in cooler air from the North Sea. Still, spots in the south and east will continue to experience heatwave temperatures. This pattern of localized cooling amid widespread heat is a reminder of how weather systems can vary significantly across relatively short distances.
Amber and yellow heat health warnings issued by the UK Health Security Agency (UKHSA) remain in place across large parts of England until 21:00 BST on Sunday. The warnings serve as a crucial reminder for residents to take precautions against the heat, especially for vulnerable populations who may be at greater risk of heat-related illnesses.
On Thursday, the heat peaked at 35.5C at Wisley in Surrey. Wales was not far behind with Bute Park in Cardiff reaching 31.3C, Charterhall in Scotland recorded 29.3C, and Killowen registered the highest Northern Ireland temperature with 27.5C. These temperatures illustrate the geographical spread of the heatwave, affecting not just southern regions but extending its reach into Wales and Scotland.
On Friday, the heat focus shifts further west into areas such as Berkshire, Wiltshire, Hampshire, Oxfordshire, and eastern Wales, where temperatures could rise to 34 or 35C in parts. Meanwhile, as high pressure shifts more towards the north of the UK, a north-easterly wind should bring a refreshing breeze inland, making eastern areas of England feel less hot. This shift in temperature dynamics highlights the complex interactions between atmospheric pressure systems and local weather patterns.
The current heatwave is not expected to break any daily temperature records; however, on Thursday the Met Office announced there have been eight days in 2026 where the heat has reached or exceeded 34C. This surpasses the previous record for the calendar year, which included two days in May, four in June, and so far two in this current heatwave. The mention of 2026 is particularly interesting, as it suggests a potential typographical error, as the current year is 2023. Such discrepancies can lead to confusion regarding the timeline of climate trends and record-setting events.
During June's heatwave, temperatures peaked at 37.7C in Lingwood, Norfolk, smashing the previous June record of 35.6C. Wales also recorded its hottest June day with 35.9C in Cardiff, while Northern Ireland equalled its June record with 30.8C in Castlederg, County Tyrone. Scotland fell just short of hitting its all-time June record, which was 32.2C set in 1893, with a top temperature of 31.2C at Threave, in Dumfries and Galloway. These records serve as a stark reminder of the changing climate and its impact on regional weather patterns, with many experts warning of the potential consequences for agriculture, water supply, and public health.
In this July heatwave, the highest temperature recorded so far has been 35.5C at Wisley in Surrey. Although temperatures will drop slightly into the weekend, many places will still reach the official heatwave thresholds through much of next week. This persistence of heat raises concerns about the cumulative effects of prolonged high temperatures on both human health and the environment.
People may be drawing comparisons with 1976, where the UK saw 16 consecutive days above 30C, but this record is not likely to be broken. The highest temperature recorded in the UK was during the unprecedented heatwave of 2022, when an astonishing 40.3C was recorded in Coningsby, Lincolnshire. Such historical comparisons are often made during extreme weather events, as they help contextualize current conditions within a broader climatic framework.
Amber heat health alerts have been issued by the UKHSA to cover all but the north-east of England, where a yellow alert is in place. The alerts are in effect until 21:00 on Sunday, indicating that significant impacts are likely across health and social care services, particularly among vulnerable populations such as those aged 65 and over, the very young, or those with existing health conditions. These alerts are crucial for prompting action among local health authorities and emergency services to prepare for potential heat-related incidents.
The effect of high daytime temperatures can be exacerbated when they fall very little overnight, not allowing our bodies enough time to recover as we try to sleep. This phenomenon, known as the urban heat island effect, can lead to increased discomfort and health risks, particularly in densely populated urban areas where concrete and asphalt retain heat.
In addition to the heat, many are also struggling with high levels of pollen. Grass pollen is dominant at this time of year, but increasingly weed pollen is becoming more prevalent. High temperatures, light winds, and a lack of rainfall can create ideal conditions for pollen accumulation in the atmosphere. Rain usually helps wash pollen out of the air, but with dry weather expected to persist for several more days, concentrations can build steadily. This interplay between weather conditions and pollen levels is particularly important for individuals with allergies, as it can significantly impact their quality of life.
Gentle breezes can also transport pollen over large distances away from immediate sources, and an easterly wind is expected in southern areas from Friday. This combination of high pollen levels, very warm days, and oppressive nights can be particularly troublesome for hay fever sufferers. The public health implications of high pollen counts during heatwaves can lead to increased demand for medical services, as those with respiratory conditions may experience exacerbated symptoms.
As the UK endures this heatwave, residents are advised to stay hydrated, avoid strenuous activities during peak temperatures, and remain aware of the health alerts in place. The advice from health authorities underscores the importance of public awareness and personal responsibility in mitigating the health risks associated with extreme weather events. As climate change continues to influence weather patterns, such heatwaves may become more frequent, making it essential for communities to adapt and prepare for the impacts of a warming climate.
