An amber extreme heat warning is in place next week.
The Met Office predicts that temperatures will reach highs of 35C from Sunday, July 17, with the hot weather continuing into the following few days. Experts say that the weather is likely to have "adverse health effects" for the public.
The Department for Education has advised schools to plan ahead to keep their pupils safe during the heatwave. Although their advice is for schools to remain open, headteachers and staff should take necessary steps to protect the children in their care.

According to the Department for Health and Social Care: "Children should wear loose, light-coloured clothing to help keep cool and sunhats with wide brims and should stay in the shade as much as possible.
"Sunscreen should be used to protect skin and children should be provided with plenty of water."
However, some Merseyside schools have still not provided guidance on school uniforms during the heatwave. There have been reported incidents of schools refusing to relax their uniform rules.
Parents at a Welsh school say that pupils were 'threatened with detention' if they wear a PE kit instead of school uniform, Wales Online reports. One parent said they are "worried" about their children having to wear a shirt and trousers in "blazing temperatures".
What do you think? Should school uniforms be relaxed?
