UK Heatwave Alert: Scorching Temperatures Return with 30°C Expected – Here's What You Need to Know

The UK is set to sizzle once again as a new heatwave sweeps across the country, with thermometers expected to hit a blistering 30°C in some areas. After weeks of unpredictable weather, summer is making a dramatic comeback, bringing sunshine and soaring temperatures that could last well into next week.

When Will the Heatwave Peak?

Forecasters predict the hottest conditions will arrive midweek, with southern and central England likely to bear the brunt of the scorching weather. The Met Office has indicated that temperatures could reach up to 30°C in London and the Home Counties by Wednesday, while northern regions will experience slightly cooler but still unseasonably warm conditions.

Health Warnings Issued

Public health officials have urged vulnerable groups – including the elderly, young children, and those with respiratory conditions – to take extra precautions during the heatwave. Dr Sarah Jarvis, a GP and clinical director, warned: "Extreme heat can be dangerous, especially for those with existing health problems. Stay hydrated, avoid the midday sun, and check on vulnerable neighbours."

Impact on Transport and Infrastructure

The soaring temperatures may cause travel chaos, with Network Rail preparing for potential speed restrictions on some routes to prevent rail buckling. Road users are advised to carry extra water and check their vehicles before long journeys, as breakdown numbers typically spike during heatwaves.

How Long Will It Last?

Current models suggest the hot spell could persist for at least five days, though thunderstorms may develop later in the week, bringing temporary relief to some areas. Bookmakers have already slashed odds on this summer being the hottest on record, with Coral offering 3/1 for the UK to experience its warmest ever July.
