It's the hottest day of the year so far in much of the West, with temperatures reaching 32 C in Gloucester and 30 C elsewhere in the region.
The Met Office issued a Level Two heatwave warning, which means the heat may have a significant effect on people's health.
There's lots to enjoy when it's sunny and warm - but here's some expert advice on staying safe too. Weston Area Health NHS Trust suggest the following:
Avoid the heat: if you’re vulnerable to the effects of heat stay out of the sun and don’t go out between 11am and 5pm (the hottest part of the day).
Keep rooms cool by using shades or reflective material outside the windows. If this isn't possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter).
Have cool baths or showers.
Drink cold drinks regularly, such as water and fruit juice. Avoid tea, coffee and alcohol.
Plan ahead to make sure you have enough supplies, such as food, water and any medications you need.
Identify the coolest room in the house so you know where to go to keep cool.
Wear loose, cool clothing, and a hat if you go outdoors.
Check up on friends, relatives and neighbours who may be less able to look after themselves.
