The UK Health Security Agency (UKHSA) has warned that a rise in deaths is expected as record-breaking temperatures, potentially exceeding 38°C, are forecast across the UK this week. The Met Office has issued an extreme amber heat warning from Monday until Thursday, flagging significant impacts on health and social care services, particularly for those aged 65 and over or with pre-existing health conditions.
Temperatures could break June records
The Met Office said there is growing confidence that this week could surpass the hottest June temperature of 35.6°C, set in 1976 in Southampton. Monday could see highs of 34°C in central southern England, rising to 37°C on Tuesday in southern England and south-east Wales. Wednesday and Thursday could reach 38°C, with potential for even higher temperatures before easing to 33°C on Friday, according to Met Office meteorologist Simon Partridge.
Health alerts and advice
UKHSA amber heat health alerts cover most of England from Monday morning until Friday night, with a yellow alert in place for the North East. People in alert areas are advised to drink plenty of fluids, keep out of the sun between 11am and 3pm, and avoid strenuous exercise. Partridge urged people to check on vulnerable individuals, including the very young and elderly, and noted that overnight temperatures above 20°C could affect sleep quality.
Transport disruptions and wildfire risks
The Met Office warned of potential disruptions to rail, road, and air travel, including possible tarmac melting. Partridge highlighted that railway lines and roads may be affected, with a risk of tarmac melting in extreme heat. In France, highs above 40°C are expected, prompting authorities to put emergency services and military forces on wildfire alert, restrict alcohol consumption in public, and cancel outdoor sporting events.
Water safety concerns
Following at least 15 deaths in open water during a hot spell in May, Partridge urged caution around bodies of water, warning of cold water shock. He recommended using a hose pipe instead of jumping into lakes to cool down.
Climate change context
Partridge noted that very hot spells are becoming more frequent due to climate change, with this being the second heatwave of the year. Last summer was the hottest on record for the UK, with a mean temperature of 16.1°C between June and August.
