A potentially record-breaking heatwave is set to scorch southern England for a week, with temperatures soaring as high as 34C in the south-east. The region's residents are bracing themselves for the prolonged hot spell, which comes on the back of a previous record-breaking heatwave last month that saw temperatures reach a provisional June record of 37.7C.
According to the Met Office, temperatures in the south will begin to climb from Saturday, reaching 28C before peaking at 29C on Sunday in the south-east. The mercury is then expected to rise further early next week, potentially hitting 34C by Thursday or Friday. Meanwhile, northern areas of the UK will experience more cloud and occasional rain, maintaining closer to average temperatures.
The UK Health Security Agency (UKHSA) has issued yellow heat health alerts across several English regions in response to the rising mercury. These alerts cover the East, East Midlands, West Midlands, South-West, London, and the South-East, and are active from midday on 4th July until 8pm on 11th July. The agency warns that these conditions could lead to minor impacts on health and social care services, increased demand from vulnerable people, and a heightened risk to life for this group.
Wales will also see temperatures climb, but no specific heat health warnings have been issued at this time. This current alert follows the previous heatwave where the Met Office issued a rare red warning for extreme heat across parts of the country, and the UKHSA implemented red heat health alerts.
With the sustained dry and hot conditions in mind, Southern Water has announced a hosepipe ban for customers in Hampshire and on the Isle of Wight, effective from 12:01 am on 10th July. This measure prohibits non-essential activities such as watering gardens with a hosepipe, filling paddling pools or hot tubs, and washing cars or patios.
Residents are advised to stay hydrated, seek shade during the hottest parts of the day (11 am to 3 pm), wear light clothing, and check on vulnerable friends, family, and neighbours. It is also crucial to be aware of the dangers associated with open water during hot weather.
