UK Schools Hit by 40C Heatwave,UK schools heatwave

Published: 11 July 2026. The English Chronicle Desk. The English Chronicle Online.
Teachers across the United Kingdom are urging the government to take urgent action after extreme summer temperatures pushed classroom conditions beyond safe limits, leaving pupils suffering from heatstroke, dehydration, nausea and exhaustion. As the country experiences another intense heatwave, education professionals say many schools are simply not designed to cope with prolonged periods of extreme heat, with indoor temperatures in some classrooms exceeding 40 degrees Celsius.

The latest heatwave has reignited concerns over the impact of climate change on Britain’s education system, prompting calls for major investment in school buildings, improved ventilation, increased tree planting and long-term climate adaptation measures.

Teachers from primary and secondary schools have described scenes of children struggling to remain conscious, complaining of headaches, dizziness and sickness as temperatures continued rising throughout the school day. Many said teaching became virtually impossible, with classrooms transformed into overheated spaces where both pupils and staff focused more on staying safe than learning.

One primary school teacher recalled children lying on classroom floors with water bottles while staff attempted to cool them using wet paper towels. Younger pupils repeatedly cried out for their parents as the oppressive heat overwhelmed them.

The teacher said there was little meaningful education taking place because everyone in the classroom was simply trying to endure the conditions until the school day ended.

Several schools reported teachers and pupils fainting during lessons, while others experienced symptoms associated with heat exhaustion, including vomiting, fatigue and severe headaches.

Many teachers revealed they had personally purchased electric fans, portable cooling equipment and window blinds because their schools lacked adequate resources to reduce classroom temperatures.

Education staff argue that such measures provide only temporary relief and fail to address the growing challenge posed by increasingly frequent heatwaves.

School buildings across Britain are particularly vulnerable because many were constructed decades ago without considering prolonged periods of extreme summer temperatures.

Large glass windows, limited natural ventilation, ageing insulation and extensive concrete playgrounds combine to trap heat throughout the day, creating environments that quickly become uncomfortable and potentially dangerous.

Many playgrounds contain artificial grass or tarmac surfaces that absorb and radiate heat, further increasing surrounding temperatures.

Unlike schools in warmer countries, relatively few British classrooms are equipped with air conditioning or ceiling fans.

Teachers with experience working overseas noted that schools in hotter climates often include cooling systems, shaded outdoor spaces and carefully designed ventilation strategies that make learning possible even during very high temperatures.

They believe British schools must now undergo similar adaptations as climate patterns continue changing.

Earlier this year, the UK’s independent climate advisers recommended that air conditioning should gradually be installed in schools over the next quarter-century, warning that Britain was increasingly facing weather conditions for which much of its infrastructure had never been designed.

Experts also recommended redesigning school grounds by replacing concrete surfaces with trees, vegetation and shaded areas capable of reducing surrounding temperatures naturally.

The current heatwave follows what meteorologists have described as western Europe’s hottest June since records began.

Britain entered its third heatwave of the year this week, with temperatures reaching 35 degrees Celsius across several regions. Forecasters expect unusually hot conditions to continue for around ten days, while scientists warn that climate change driven by greenhouse gas emissions is making extreme weather events increasingly common.

The impact on schools has already been significant.

During June’s heatwave, more than one thousand schools across England and Wales either closed completely or partially suspended classes because conditions became unsafe.

Official education statistics showed one in every five school sessions in England was missed during the period, representing the highest daily absence rate recorded during the current academic year.

Experts say widespread school closures have consequences far beyond education.

Parents are often forced to remain at home to care for children, disrupting workplaces and reducing economic productivity.

Research by the campaign organisation Round Our Way estimates that the June heatwave alone cost the British economy between £100 million and £200 million through school closures, workplace disruption and reduced productivity.

The organisation argues that adapting schools to extreme weather should become a national priority rather than leaving individual schools responsible for finding their own solutions.

Round Our Way has called on the government to develop a comprehensive climate resilience strategy covering education, public health and infrastructure while continuing efforts to reduce carbon emissions responsible for rising global temperatures.

A nationwide survey commissioned by the organisation found that more than half of British parents reported at least one child missing school during the June heatwave.

Forty percent said their children returned home overheated and exhausted, while nearly half reported youngsters being unable to play outdoors because temperatures were simply too high.

Almost two-thirds of parents surveyed said British summers were beginning to feel genuinely unsafe for children, reflecting growing public concern about the country’s changing climate.

The National Education Union has also raised alarm over classroom conditions.

Jenny Cooper, a teacher and union safety representative in London, said recent heatwaves had exposed serious weaknesses in Britain’s school infrastructure.

She reported hearing of colleagues collapsing because of excessive heat while photographs shared by teachers showed classroom thermometers registering temperatures well above accepted workplace safety levels.

According to Cooper, schools should provide safe environments where children can learn and teachers can work without risking their health.

Medical professionals have echoed those concerns.

Dr Lorna Powell, an urgent care physician in east London and co-director of the climate campaign group Mothers Rise Up, described the recent heatwaves as deeply worrying both as a doctor and a parent.

She said school closures had made climate change a much more immediate issue for many families who previously paid little attention to environmental debates.

Parents now increasingly recognise that the hotter summers experienced in recent years differ dramatically from those of previous generations.

Dr Powell believes growing awareness of extreme weather is encouraging more people to consider the links between fossil fuel emissions, climate change and the increasing frequency of dangerous heatwaves.

The Department for Education maintains that schools themselves remain responsible for deciding whether conditions are safe enough to remain open.

Government guidance encourages schools to continue operating wherever possible while ensuring pupils stay hydrated, adjusting uniform requirements where appropriate and avoiding strenuous physical activities during the hottest parts of the day.

However, many teachers argue that these temporary measures are no longer sufficient as extreme heat becomes an increasingly regular feature of British summers.

Education leaders warn that without significant investment in school infrastructure, future heatwaves will continue disrupting learning while placing the health of millions of pupils and staff at unnecessary risk.

As climate experts forecast hotter and longer summers across the United Kingdom in coming decades, calls are growing for a nationwide programme to modernise schools so they remain safe, resilient and capable of providing quality education regardless of rising temperatures.
