The Met Office has placed all regions in the southern half of the country under this weather advisory.

Exposure to the sun’s rays will today reach 8 on a scale from 1 to 11, with 8 falling in the red, which calls for people to avoid spending prolonged periods in the sun between noon and 4pm.

Children are also asked to avoid being outdoors during that period, while the use of sun cream, sun glasses and hats are recommended to everyone.
