The UK is bracing for a heatwave with temperatures expected to reach 38C this week, prompting questions about school closures. However, current government guidelines advise that schools should remain open, as "school attendance is the best way for pupils to learn and reach their potential, and hot weather can usually be managed safely," according to the Department for Education (DfE).
Government Advice for Schools During Hot Weather
The DfE recommends that schools consider relaxing uniform rules to ensure pupils are comfortable. Children should wear loose, light-coloured clothing and sunhats with wide brims. When outdoors, pupils should be encouraged to stay in the shade as much as possible. Sunscreen with high sun protection factors should be used, and teachers should encourage children to remove blazers and jumpers.
No Official Maximum Temperature
While there is no official maximum temperature that triggers school closure, the National Education Union (NEU) suggests that 26°C should be an appropriate point to initiate additional measures. The NEU states: "Other steps may also need to be considered such as closing classrooms which are unacceptably hot and teaching classes elsewhere, or even sending pupils home, provided reasonable notice has been given to parents."
Practical Steps for Classrooms
The government adds: "If possible, open classroom doors as well as windows to encourage cross ventilation in single sided classrooms." Windows should be opened early in the morning before children arrive or preferably overnight to release stored heat, while checking insurance and security conditions. Windows should be closed when outdoor air becomes warmer than indoor air to keep heat out while maintaining ventilation. Indoor blinds or curtains can be closed where possible without blocking ventilation, and CO2 monitors can be used to monitor air quality. Electric lighting should be minimized, and equipment should not be left on standby as it generates heat. Mechanical fans can be used if temperatures are below 35°C; above that, fans may not prevent heat-related illness and could worsen dehydration. Schools are advised to provide and encourage children to drink more water than usual.
Heatwave Context
The heatwave affecting the UK and much of Europe is driven by a strong area of high pressure over the continent, creating a "heat dome" that traps hot air. Parts of France, Italy, and Spain have seen temperatures exceed 40C.
