Temperatures are set to continue to rise

The Met Office have confirmed that today is the hottest May day ever recorded in the UK as temperatures have soared to 34.8C.

According to the Met Office, the previous May record stood at 32.8C.


The previous temperature was recorded in Camden Square on May 22 1922 and then again in Horsham, Tunbridge Wells and Regent's Park on May 29 1944.

The record has been smashed today at Kew Gardens in south-west London, with temperatures expected to reach 35C.

Officials have warned that people must stay safe in the soaring temperatures, especially those heading to the coast.

Ashley Jones, Head of Water Safety & Education at Royal Life Saving Society UK, said: "As air temperatures rise, it’s important people don’t underestimate the risks associated with entering open water.

"Even during a heatwave, water will remain dangerously cold, and cold water shock is a very real danger. Sudden immersion can cause an involuntary gasp, rapid breathing and panic, which can quickly lead to a loss of control in the water - even for strong swimmers.

"We’re urging the public to choose lifeguarded locations wherever possible, where safety measures and supervision are in place.

"If you are spending time near water with children, always supervise them closely, keep them within arm’s reach, and consider dressing them in brightly coloured swimwear to improve visibility.

"Open water environments are very different from controlled swimming areas. There may be hidden hazards beneath the surface, strong currents, and colder temperatures that can seriously affect your ability to swim.

"It’s vital to respect your limits, avoid swimming alone, and talk to your family about water safety before you visit."

The record high temperatures are as a result of climate change.

Senior Met Office meteorologist Greg Dewhurst, told Sky News: "We see these changes happening so much more dramatically.

"In the past, heatwaves built and built and built and built over days and days and days – these now just develop so quickly.

"It's huge sort of swinging temperatures, and obviously records being broken by day and by night, so it just shows sort of how extreme the weather can change, and how quickly it can change as well."

Dr Anya Gopfert, Consultant in Health Protection at UKHSA, said: “We know that even moderate heat can lead to serious health problems, especially for older people and those with certain health conditions, so it’s important that everyone takes simple precautions while enjoying the warm weather over the coming days.

“If you have friends, family or neighbours who are more vulnerable, it is important to check in on them and ensure they are aware of the forecasts and are following the necessary advice.”

In the high heat, the British Red Cross has offered support to keep you safe.

Dafydd Beech, National Community Education Manager, said: “As we come into the summer months, warm weather gives us a chance to get out a bit more and enjoy ourselves. It’s important to take care while you have fun with friends and family to avoid becoming dehydrated, getting sun burn or even heat stroke.

“Getting into the habit of taking steps whenever temperatures rise can really help. It can be simple things like wearing sunscreen, drinking plenty of fluids or ensuring you take breaks from the sun. Building these habits early means people are better prepared if hotter weather lasts longer.”
