EXPERTS are warning about the health risks of heatwaves as temperatures continue to climb across the country.

Temperature across North Wales is set to hit 30C before Friday, leading forecasters and medics to tell people to stay safe in the sun and take extra precautions.

The temperatures will reach 29C in Bangor, while Llandudno and Rhyl will reach 30C.

Wrexham will see temperatures hit 29C and Hawarden in Flintshire will see temperatures hit 31C on Thursday.

Warnings have been issued about UV levels, which are going to be "exceptionally high" over the next couple of days.

Met Office meteorologist Alex Burkill told PA: "The sun is as strong as it gets at the moment because we're so close to the solstice.

"We've got peak sun strength, clear skies, plenty of sunshine - it's the perfect ingredients for high UV."

Mr Burkill advised anyone outside for prolonged periods of time on Wednesday and Thursday should take measures to protect themselves and nights will also be 'uncomfortably hot'.

Shoppers have also been advised to be aware they could be forced to spend extra time in the sun as a result of social distancing measures.

Dr Lynn Thomas, Medical Director at St John Ambulance added:"You could end up in the sun for longer than expected on what would normally be a quick journey, such as queuing to enter the supermarket, so you should be prepared to look after yourself and others.

"Heat exhaustion and heatstroke are two of the most serious problems that can develop when the mercury soars but by being prepared you can spot the early warning signs, such as headache and dizziness."
