The are also warnings in nearby Portugal, as well as fellow European Union nation Greece. The Met Office warned: "The heat can affect your health and make you feel unwell, there are many simple things you can do to keep yourself safe. Keep out of the sun and avoid any exercise between 11am to 3pm when the sun is the strongest.

"If you are going out, take water with you, keep in the shade, wear sunscreen and wear a wide-brimmed hat." The Met Office advised: "Check the water temperature, our seas and river temperatures are low enough to cause cold water shock when 15C or lower.

"Wear a wetsuit if you plan on spending any length of time in the water. Wearing a life jacket or swimming buoy can increase your chances if you experience cold water shock." The Met Office's advice to stay safe in the heat was published on its website.

The UK Met Office is responsible for issuing weather forecasts and making short, medium and long term projections over what lies in store for parts of Britain.
