The Met Office has issued an amber heat health alert for four areas as a heatwave is expected to bring temperatures of 34C or higher this weekend.
Amber Alert Issued for Four Regions
An amber heat health alert has been issued for the East, South East, and South West of England, as well as London. The alert came into effect at 12pm on Thursday and will remain in place until 8pm on Tuesday.
Temperature Forecast
Parts of the South and South East are likely to exceed the heatwave threshold over the weekend. The Met Office warns there is a 40% chance of surpassing the all-time June temperature record of 35.6C, set in 1957 and 1976. East Anglia could see highs of 32C on Friday, followed by a brief cooldown to 28C on Saturday. However, temperatures will rise again on Sunday, reaching 32C in the South and South East, and potentially 34C or more on Monday.
Met Office meteorologist Alex Deakin described these temperatures as "pretty unusual even for the middle part of June."
Thunderstorms and Humidity
The intense heat may trigger thunderstorms across the South East and East Anglia on Sunday. Deputy chief forecaster Gregory Wolverson noted that the scorching spell might not bring "wall-to-wall sunshine and blue skies" like the May heatwave. Cloud cover and high humidity could make conditions feel "rather oppressive at times."
Health Warnings
The UK Health Security Agency's amber health warning indicates an "increased demand" on health and social care services, potentially leading to a rise in deaths. Those aged 65 and over and people with underlying health conditions are most at risk, though younger age groups may also be affected. Yellow health alerts have been issued for the East and West Midlands, warning of minor service disruptions.
Water Safety Advice
Following the May heatwave, which saw 15 deaths in open water, the RNLI has issued safety advice. Samantha Hughes, national water safety partner, warned: "With warmer weather approaching, it's important to remember that the water is still cold. Entering it unexpectedly can lead to cold water shock, causing a sudden increase in breathing and heart rate, which may trigger panic." She advised: "If you find yourself struggling in the water, remember to Float to Live: tilt your head back so your ears are submerged, relax and control your breathing. You may need to gently use your hands to help you stay afloat, and it's ok if your legs sink - everyone floats differently."
