The Met Office has warned the public to practice caution as temperatures are set to hit 34 degrees in the coming days.
They issued an amber heat-health warning this morning, which will remain in place until 9am on Friday, July 27.
They have advised people to stay out of the sun during 11am to 3pm, as this is when the sun is the strongest.
They warned: “Stay out of the sun. Keep your home as cool as possible – shading windows and shutting them during the day may help.”
“Open them when it is cooler at night. Keep drinking fluids. If there's anybody you know, for example an older person living on their own, who might be at special risk, make sure they know what to do,” they advised.
They have also asked the public to protect their skin if they must go outside. They recommend wearing a sunscreen with a high SPF and wearing loose clothing.
The public has also been reminded to stay hydrated during the warm weather. It is recommended that you boost your water intake when the temperature is above average to avoid dehydration.
They stressed the importance of wearing hats and sunglasses during the heatwave.
The hottest day of the year so far was on June 28. Temperatures of 33 degrees were recorded in Porthmadog, North Wales.
