Britons were told: "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."
Britons were also advised to drink plenty of fluids and close their curtains in rooms that face the sun.
On public transport, holidaymakers should carry water with them and ensure they drink lots of fluids, If get off public transport for some fresh air if feeling unwell, wear light, choose light fabrics in light colours, and carry a small hand-held battery fan.
If you are in a position to help others, apply ice packs or cold compresses to the person's wrists, neck, and elbows to help them cool down quickly.
Swimming in a pool or the sea can be an extremely enjoyable activity on holiday, but it's important to stay safe.
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."
