WITH highs of 30C expected, today is set to be a scorching hit with sun worshippers.
But as the mercury rises in Nottingham, some schoolchildren and workers will be getting hot under the collar.
Schools are being forced to balance the need for strict uniform guidelines with ensuring students can keep cool.
And that has led one mum into conflict with her daughter's school.
Emily Cope, 12, said she was told by a teacher at Big Wood School to put her blazer back on after she'd taken it off during the warm weather, to the anger of her mum.
Lydia Dundon, 32, believes the school, in Warren Hill, near Top Valley, should relax its guidelines to allow students to stay cool.
"She struggles with the heat anyway, so she was walking outside with her blazer off when a teacher asked her to put it back on, even though he was just wearing a short-sleeved shirt," said Miss Dundon, of Bestwood Park.
"I think it is right that a school has a proper policy around uniforms but when the weather is so hot, they need to be more sensible about it."
In a letter to parents at the start of the summer, head teacher Andrea Healey reaffirmed the policy surrounding blazers.
She said: "During periods of warm weather, pupils are expected to wear their blazer to school.
"Pupils will be allowed to remove their blazer during lessons with the permission of the member of staff and whilst sitting and relaxing or playing sports during unstructured times."
An additional note on the school's website tells parents that it has high standards for uniforms, saying "it creates a sense of belonging, and reduces arguments at home about what is or isn't acceptable dress for school".
It is set to be warm throughout today but temperatures are expected to be at their highest, 30C, at about 4pm, at the end of the school day.
It will remain warm throughout the evening, though the dry weather will make way for heavy downpours tonight and into tomorrow.
The city council has issued guidance to schools and other businesses on how to take precautions for vulnerable people such as children.
A spokesman said: "With the mercury rising in Nottingham, public health officials at Nottingham City Council have issued advice on staying sun safe, and looking out for vulnerable people.
"Even if temperatures do not hit extreme levels, Public Health England still advises people to keep safe in the sun, seek shade to cool down and keep hydrated with plenty of cool fluids."
The hot weather has sparked a level two heatwave alert from the Met Office. This means there is a high chance that temperatures over the next few days could pose significant health risks.
Among the most vulnerable are the elderly and the very young, as well as people with chronic or long-term medical conditions.
It has prompted Age UK Notts to issue advice for the elderly for how they can keep cool.
The charity says they should stay indoors during the hottest parts of the day, drink plenty of cold fluids and wear a hat as well as a high-factor sun cream or block for essential trips outside.
Caroline Abrahams, charity director at Age UK, said "The importance of staying cool in hot weather cannot be overstated for older people, especially if there are successive hot days. It is extremely important that older people take sensible precautions during a heatwave, particularly if they have breathing problems or a heart condition.
"Anyone with an older family member or neighbour can help by calling in to check to see if they are OK and if they need help in taking reasonable precautions to stay well in the hot weather.
"Helping out by bringing in shopping may be especially valued if it means older people don't have to be outside in the sweltering heat."
With the temperatures rising, many people will be doing what they can to try to keep cool.
But they are being warned against jumping into canals and rivers.
Tony Stammers, head of health and safety with the Canal and River Trust, said: "Inland waters such as canals, rivers and reservoirs may look inviting on a hot summer's day, but any open body of water can pose a hazard, as the water can often be extremely cold and can bring on cramps in even the strongest swimmers and there may be hidden objects lurking beneath the surface."
