Last updated 9th Aug 2022
The UK Health Security Agency has issued a 'Heat Health Alert' for the whole of England, from Cornwall to Cumbria.
The alert will be in force from midday on Tuesday 9 August to 6pm on Saturday 13 August for all regions of England, while an amber alert from the Met Office will remain until 9pm on Sunday 14th August.
The Met Office has since issued an amber 'Extreme Heat' weather warning for most parts of England, spanning Thursday to Sunday.
Temperatures are not forecast to reach the record-breaking levels of the most recent heatwave but are expected to rise throughout the week, potentially reaching mid-30 degrees Celsius on Friday and Saturday in the South East, London, the South West, and the East and West Midlands.
Dr Agostinho Sousa, Head of Extreme Events and Health Protection at the UK Health Security Agency (UKHSA), said: "Temperatures will feel very warm again this week, particularly in southern and central parts of the country.
"We want everyone to enjoy the warm weather safely when it arrives but remember that heat can have a fast impact on health. It's important to ensure that people who are more vulnerable – elderly people who live alone and people with underlying health conditions – are prepared for coping during the hot weather.
"The most important advice is to ensure they stay hydrated, keep cool and take steps to prevent their homes from overheating".
Met Office Deputy Chief Meteorologist, Tony Wardle, said: "Heatwave criteria look likely to be met for large areas of the UK later this week, with the hottest areas expected in central and southern England and Wales on Friday and Saturday. Temperatures could peak at 35⁰C, or even an isolated 36⁰C on Saturday.
"Elsewhere will see temperatures widely into the high 20s and low 30s Celsius later this week as temperatures build day-on-day through the week due to an area of high pressure extending over much of the UK.
"Coupled with the high daytime temperatures will be continued warm nights, with the mercury expected to drop to only around low 20s Celsius for some areas in the south".
Tip tips for staying safe during the hot weather
The UK Health Security has the following advice:
Look out for those who may struggle to keep themselves cool and hydrated – older people who may also live alone, and those with underlying conditions are particularly at risk
Stay cool indoors by closing curtains on rooms that face the sun – and remember that it may be cooler outdoors than indoors
Drink plenty of fluids and avoid excess alcohol
Try to keep out of the sun between 11am to 3pm, when the UV rays are strongest
Walk in the shade, apply sunscreen and wear a wide-brimmed hat, if you have to go out in the heat
Avoid physical exertion in the hottest parts of the day
Make sure you take water with you if you are travelling
Check that fridges, freezers and fans are working properly
Check medicines can be stored according to the instructions on the packaging
Never leave anyone in a closed, parked vehicle, especially infants, young children or animals
Take care and make sure to follow local safety advice if you are going into the water to cool down
The UK Health Security Agency added: "High temperatures also present a risk of wildfires, especially after long dry periods.
"People with pre-existing heart and lung conditions such as asthma are most susceptible as breathing wildfire smoke may worsen their symptoms. Children and older people may also be susceptible to health impacts.
"If wildfire smoke affects your area, avoid or reduce your exposure to smoke by staying indoors with the doors and windows closed.
"Where possible avoid smoky areas. If you should travel through a smoky area, ensure that the vehicle windows are closed and the air conditioning is switched to recycle or recirculate if possible.
"Listen for local news reports and information from the emergency services who will provide advice on the precautions you should take".
