Heatwave in England and Wales set to last into next week

A relentless heatwave baking England and Wales is set to continue well into next week, the Met Office confirmed, with temperatures in parts of the southeast expected to hit 34°C by Wednesday. There’s little relief on the horizon for the millions of people already struggling through days of sweltering heat, disrupted travel, and health warnings from NHS authorities.

What the forecasters are saying

The Met Office issued a Level 3 heat health alert covering large swathes of England, the second-highest level in a four-tier warning system. Forecasters say an area of high pressure anchored over the UK is essentially locking the hot air in place, preventing the cooler Atlantic systems from breaking through. It’s an unusual setup for this time of year, and one that meteorologists say could persist for at least another five to six days.

“We’re looking at a prolonged spell of heat that will affect a wide area,” said a Met Office spokesperson. “Overnight temperatures will also stay high — potentially above 20°C in urban areas — which makes it very difficult for people to recover.”

Records and real-world impact

Some weather stations in the Home Counties recorded highs of 32°C over the weekend. Rail operators have already begun imposing speed restrictions on certain routes, citing the risk of track buckling. And at least three water companies have issued hosepipe bans, warning that reservoir levels are dropping faster than expected.

Hospitals and care homes are on heightened alert. Health officials are particularly worried about the elderly and those with existing cardiovascular or respiratory conditions. The UK Health Security Agency estimates that excess deaths during prolonged heat events can run into the hundreds.

This isn’t just uncomfortable. For vulnerable people, it can be genuinely dangerous.

How people are coping

In city centres from Cardiff to Birmingham, parks and fountains have become makeshift refuges. Pharmacies report a surge in demand for sun cream, electrolyte drinks, and cooling fans — with some stores already running low on stock. Swimming pools in several local authority areas have extended their opening hours, though staff shortages are making that difficult to sustain across the board.

Meanwhile, schools are adapting. Several headteachers in London and Kent have written to parents relaxing uniform rules and adjusting timetables to keep children away from direct sunlight during peak afternoon hours.

What comes next

So when does it end? Models suggest a gradual breakdown of the high-pressure system toward the end of next week, potentially bringing thunderstorms to parts of the Midlands and the north. But forecasters are cautious — the timing of that shift remains uncertain, and it won’t necessarily bring immediate cooling to the south.

For now, England and Wales are bracing for several more days of exceptional heat, and authorities are urging people to check on elderly neighbours, stay hydrated, and avoid the midday sun wherever possible.
