More than 1,000 schools across England and Wales are closing or finishing the day early this week to protect students against extreme heat.
Teachers and pupils are struggling to cope in school buildings never designed for sky-high temperatures fuelled by global warming.
Twelve school days a year could be lost
With the UK experiencing increasingly extreme weather, temperatures in schools have become a “major concern”, said The i Paper.

Modelling by the Met Office and University College London for the Department for Education published last year found some schools may already have one or two days a year when indoor temperatures hit 35C and learning becomes “very difficult”.
But “without the implementation of any adaptation measures, students could potentially lose up to 12 days of learning per year on average, as result of generally warmer temperatures and not just from extreme heat”.
There is evidence that children struggle to sleep at night when temperatures remain above 20C. So government guidance warns teachers and school leaders to look out for the symptoms of “heat stress”, including discomfort, irritability and signs of dehydration.
“The kids can’t cope,” said Nottingham junior school teacher Radhika Sanghani in The Independent. “One of the kids didn’t sleep well because of the heat, so he was falling asleep at his desk, literally dozing. They’re only seven to nine years old. It’s a lot to expect them to study in that heat. They’re tired, they’re red-faced, they’re finding it all horrendous.”
Extreme heat is already forcing schools to postpone sports days and cancel trips, while some primaries are having to resort to “hot play”, where children are kept indoors because it is simply too hot to go outside.
Air conditioning ‘only real solution’
The problem is that most schools are not built to cope with temperatures that regularly hit 35C.
“Many schools don’t have any ventilation systems other than opening and closing windows,” said Tim Fulford, a teacher and National Education Union health and safety representative. In some of the newer Blair-era private finance initiative (PFI) schools “you can’t even do that”.
Last month, a landmark report from the government’s Climate Change Committee warned the UK is “built for a climate that no longer exists today and will be increasingly distant in years to come”.
Among its many recommendations was a call for air conditioning be installed in all schools within 25 years.
This is the “only real solution”, said Sanghani, “but they’re never going to fit out all schools with AC. The cost would be astronomical.”
In the meantime, the CCC has said exams should be held at cooler times of the year. It cited research that showed taking a test on a 32C day reduces a pupil’s chance of passing by around 10% compared with a 22C day.
The UK Health Security Agency has gone further, advising that schools should “consider rearranging school start, finish and play times to avoid teaching during very hot conditions”. This happens in countries like France, which have longer summer holidays and have earlier start and finish times on very hot days.
“That would still be an inconvenience for parents to have to find childcare solutions, but it’s the best solution I can think of,” said Sanghani. “I’d personally be very happy to start the teaching day earlier when it’s cooler and head home by the time it gets unbearable.”
