UK Swelters Under 'Very Rare' Heatwave: Met Office Issues Dire Warnings

The United Kingdom is bracing for an extreme and potentially record-breaking heatwave this week, with the Met Office issuing an amber heat warning from Monday, June 22 until Thursday, June 25. Temperatures are forecast to approach a remarkable 40C in some areas, with peaks of 38C expected on Monday and Tuesday, and Greater Manchester set to reach 37C by Thursday. Forecasters express growing confidence that this period could break the record for the hottest June temperature of 35.6C, set in Southampton in 1976. The UK Health Security Agency (UKHSA) has also issued separate amber heat health alerts covering the majority of England, including Greater Manchester, from Monday morning until Friday night, warning of significant impacts on health and social care services.

This unprecedented heat has raised serious concerns regarding the millions of pupils and teachers in busy classrooms. Teachers, unions, schools, and parents have all voiced worries about rising classroom temperatures, which can make concentration difficult, especially for pupils with special educational needs. A Deputy Head from a London secondary school highlighted the struggle, stating that staff find it hard to function properly during the hottest days, impairing both teaching and learning. While no formal school closures have been declared, there is mounting pressure on the Government to establish regulations permitting schools to close when temperatures reach dangerously high levels. Both the Climate Change Committee (CCC) and the Trades Union Congress (TUC) support demands for a maximum temperature threshold in classrooms, with the Department for Education (DfE) confirming it is 'carefully considering' these proposals. The Education Secretary, Bridget Phillipson, acknowledged the challenging conditions extreme heat creates for teachers, staff, and pupils' capacity to learn. In the interim, schools across the UK are implementing precautionary measures, advising pupils to bring refillable water bottles, hats for outdoor wear, and apply sunscreen. Some schools, like one in Wiltshire, have relaxed uniform policies, allowing students to wear PE kits or standard uniforms without jumpers and ties.

The heatwave also brings challenges for workplaces, with many questioning whether they must work in such conditions. Unlike some other countries, the UK does not have a specific legal maximum temperature at which employees are automatically sent home. However, employers are legally obligated to maintain a 'reasonable and comfortable' temperature in the workplace. If temperatures become excessively high, creating unsafe or unhealthy conditions, employees may have grounds to raise concerns and potentially leave if they reasonably believe there is 'serious and imminent danger.' Guidance on the gov.uk website advises employers to assess the risks of high temperatures and implement control measures such as providing ventilation, cooling equipment, or allowing for breaks. While there is no guidance for a maximum temperature limit, health and safety at work law requires employers to keep the temperature at a comfortable level and provide clean, fresh air. Employees are encouraged to communicate with their employers if their workplace temperature is not comfortable.

Beyond schools and workplaces, the extreme heat is expected to have broader societal impacts. The UKHSA warns of a rise in deaths, particularly among those aged 65 and over or with existing health conditions. Meteorologist Simon Partridge noted the 'very unusual, very rare spell of very hot weather,' urging people to take care, keep their houses as cool as possible, and check in on vulnerable individuals. He also highlighted potential disruptions to transport, including issues with railway lines and the possibility of tarmac melting on roads. The extreme heat means people may not get adequate sleep, affecting everyone. Hottest temperatures are expected between Bristol and London and south of the M4, with most of England and Wales experiencing temperatures over 30C.
