The time has come to alert your punters boozing in the sun, and make sure the umbrellas are up, as temperatures look set to tip 35 degrees Celsius this week.


Official advice from the Met Office has been issued and it calls for people to 'stay out of the sun' completely.

The heatwave looks set to continue until at least the end of the week with temperatures cooling a little next week – but rain still isn't on the cards.

The weather firm said to keep windows shaded and even shut them during the day – only opening during the night when it was cooler.

It also called on people to make sure they drink enough fluids, but not alcohol, which is dehydrating – so maybe offer a jug of tap water to tables heading out the garden.

The Met Office said: "Whilst many of us like to enjoy the sunshine and hot weather, we should make sure we do it safely and remember certain groups of people are more vulnerable than others to heat or ultraviolet radiation.

"Extreme heat can force the body into overdrive as it tries to stay cool through perspiration and evaporation. Young children and older people are particularly at risk. Overexposure to sun is equally dangerous, with effects ranging from mild sunburn to skin cancer. It doesn't have to be hot for the UV index to be high."

It follows advice from Public Health England, who has called on people to keep out of the sun between 11am and 3pm – and to only walk in the shade.

The Environment Agency has said water supplies should be okay at present across most of Britain.
