The UK Health Security Agency (UKHSA) has issued amber health alerts for heat as the Met Office warns of a heatwave more severe than the one in May. Millions of people in London, the south-east, south-west and east of England are affected, with the alerts in force from Thursday afternoon until 8pm on Tuesday June 23.
Amber Alert Impacts
The amber alert indicates that “significant impacts are likely across health and social care services due to the high temperatures, including a rise in deaths, particularly among those aged 65 and over or with health conditions. There may also be impacts on younger age groups,” the agency warned. The heat could also affect “the ability of the workforce to deliver services” in the affected areas as temperatures are likely to rise into the mid 30s. The east and west midlands are under yellow heat health alerts, meaning they may also see impacts on services.
Forecast Details
An incoming high pressure system will leave much of the country “feeling increasingly hot with temperatures well above the June average.” Temperatures are expected to reach the high 20s Celsius widely, with potential for 32°C in the south of England on Sunday and 34°C or higher on Monday. Conditions will remain humid, increasing the risk of thunderstorms.
Met Office meteorologist Honor Criswick said: “It’s a bit different to the last heatwave, because last time the humidity wasn’t as high, whereas this time the humidity is quite a bit higher. It’s just going to make it feel that bit muggier and more humid during the day and overnight, so it means it’s going to be more uncomfortable.” She added: “Because the humidity is so high, there’s a chance that this could spark off some thunderstorms. They could pop up anywhere, particularly across central, southern, south-east England. Wherever they hit, it’s likely to be an intense, heavy downpour with thunder and lightning.”
Comparison to Previous Heatwave
A record-breaking heatwave in May saw May 26 become the hottest May day on record for England and Wales, with 35.1°C at Kew Gardens and 32.9°C at Cardiff Bute Park. A heatwave is defined as three consecutive days with daily maximum temperatures meeting or exceeding the heatwave threshold.
Water Safety Warning
The UKHSA heat health alerts also warn of water-related incidents, including cold-water shock and drowning. During the May heatwave, 19 children and adults died in water-related incidents in one week. The Mirror launched the ‘Save Lives for Sam’ campaign to stop the “catastrophic” deaths of 33 children who drown in England every year.
Samantha Hughes, RNLI National Water Safety Partner, said: “With warmer weather approaching, the water is still cold. Entering unexpectedly can cause cold water shock, increasing breathing and heart rate, triggering panic. If you struggle, remember to Float to Live: tilt your head back, relax, control your breathing. Always choose a lifeguarded beach and swim between red and yellow flags. In a coastal emergency, call 999 for the coastguard.”
