Parts of Britain are bracing themselves for some sweltering temperatures over the next few days, with some areas predicted to be hotter than the Caribbean.
The Met Office says several days of baking weather, set to start on Thursday and last until Sunday, could see the mercury reach 37C (98.6F).
This would mean some parts could pass the threshold for an “official heatwave”, which requires three days of temperatures over 25C (77F).
The record temperatures are likely to see Brits flocking to the beaches, but how can you keep yourself safe in a heatwave?
What are the main risks of a heatwave?
According to the NHS, the main risks of basking in the sunshine are dehydration, overheating, and heat exhaustion or heatstroke.
Anyone can be affected, but the most vulnerable include: older people — especially those over 75; people with serious of long-term illnesses and those who find it hard to keep cool like babies and the very young.
The British Red Cross warns of the possibilities of sunburn and heatstroke while relaxing on the beach.
The organisation’s website says: “Whether you're going abroad or enjoying a 'staycation' in the UK, heading to the coast is a great way to keep cool in the hotter weather.
“The sea breeze and regular dips in the sea help keep your body temperature down, but bear in mind that the sun is still very strong and precautions must be taken.”
Prevention is always better than cure, the Red Cross advises, so make sure you use high factor suncream.
If you do get sunburn, move into the shade, sip cold water, and dab the affected skin with cold water. Make sure you apply after-sun later on to soothe the area.
Heatstroke happens when the body gets so hot it can't control its temperature. According to the Red Cross, symptoms include: hot, flushed, dry skin; headache, dizziness and being confused and restless; becoming unresponsive.
If you think someone has heatstroke you should call 999 immediately. Cool the person down by moving them into a cool environment and taking off any outer clothing. You can also wrap them in a cold, wet sheet.
How to stay safe in the water
As people pour to the beaches, the RNLI has urged families to be aware of potential dangers following its busiest day for four years involving more than
The Coastguard reported its busiest day for more than four years as it dealt with more than 300 incidents.
Ahead of this week’s sunny spell, Gareth Morrison, RNLI head of water safety, said: “Our coastline is a fantastic place to spend time together as a family, especially when the sun is out and it’s hot.
“But there are also plenty of potential dangers, especially for those who aren’t fully aware of their surroundings and may be visiting a particular beach for the first time.
“We are advising everyone planning a visit to a beach or the coast to follow (the) beach safety advice.”
The RNLI advises parents not to allow children to use inflatables as they can be swept out to sea and also reminds parents to be aware of rip currents.
