Lincolnshire residents are being warned to stay safe in the summer sun during the highest temperatures of the year.
With temperatures expected to reach 29C, the Met Office has issued a yellow warning across the county.
An official heat health warning is triggered when temperatures are high enough on two consecutive days and during the night to have a significant effect on health.
Cllr Mrs Patricia Bradwell, executive member for Public Health said: “High temperatures can be dangerous, especially for people who may be particularly vulnerable such as older people, infants and those with serious illnesses, so look out for family, friends and neighbours during the heatwave. Everyone can enjoy the sun safely by following common sense measures such as keeping out of the heat at the hottest time of the day, avoiding sunburn and drinking plenty of water.”
