UK Heatwave Expected as Temperatures Near Record Highs for May
The United Kingdom is bracing for a heatwave this bank holiday weekend, with temperatures expected to approach or break the May record of 32.8 degrees Celsius. Forecasters predict that the mercury could soar to 34 degrees Celsius on Monday, prompting amber health alerts across much of England.
The Met Office has indicated that a heatwave may be officially declared in parts of the UK on Sunday, as temperatures have already reached the threshold for three consecutive days. At midday on Sunday, readings at Heathrow showed temperatures hitting 28 degrees Celsius, meeting the criteria for a heatwave declaration in London and surrounding areas.
On Saturday, a temperature of 30.5 degrees Celsius was recorded in Frittenden, Kent, marking the highest reading of the year so far. Sunday is expected to see highs of 31 degrees Celsius in the southeast, with Monday potentially bringing peaks between 33 and 34 degrees Celsius.
The climate crisis is amplifying the likelihood of such extreme heat events. Large portions of western Europe are experiencing similar conditions, with Météo-France warning that periods of exceptional heat are becoming more frequent, more premature, and more intense.
A Met Office spokesperson stated: “Breaking the 32.8°C May record is around three times more likely now in our current climate than it would have been in natural climate conditions before the Industrial Revolution. What was around a one-in-100-year event is now around a one-in-33-year event.”
Met Office meteorologist Jonathan Vautrey noted that there will be “plentiful amounts of sunshine” across many parts of the UK on Sunday, driving temperatures above 30 degrees Celsius. “If we hit that 33°C, maybe even locally close towards 34°C, that would bring us our hottest bank holiday day on record, as well as our hottest day in May on record,” Vautrey said. “So it really is quite exceptional heat that is building for the time of year.”
Heatwave Thresholds Across the UK
The criteria for a heatwave are set by the Met Office. A heatwave is declared when temperatures reach or exceed 28 degrees Celsius in London and its surrounding counties on at least three consecutive days. For many other areas of England, as well as southeast Wales, the threshold is 26 or 27 degrees Celsius. For Scotland, Northern Ireland, much of Wales, and northern England, the threshold is 25 degrees Celsius.
Saturday marked the UK’s first 30-degree Celsius day of the year, with May 23 being the earliest date such a temperature was reached since 1952.
Impact on Sports and Events
In response to the hot weather, Lord’s Cricket Ground has relaxed its strict dress code in the pavilion. The Marylebone Cricket Club usually requires spectators to wear lounge suits or tailored jackets and ties, but that requirement has been eased for the duration of the heatwave.
During yesterday’s Championship playoff final between Hull and Middlesbrough at Wembley, drinks breaks were implemented. Similar breaks occurred in the playoff between the WSL’s Leicester City and Charlton Athletic. Additional refreshment breaks are expected in Sunday’s Premier League games as the season concludes, as well as at the League One playoff final between Bolton Wanderers and Stockport County at Wembley.
Health Alerts and Precautions
The UK Health Security Agency (UKHSA) issued amber heat health alerts on Friday morning for the East Midlands, West Midlands, east of England, London, and the southeast. These alerts will remain in effect until 5 p.m. on Wednesday. According to the UKHSA website, the alerts indicate a likely rise in deaths, particularly among individuals aged 65 and over or those with health conditions, as well as increased demand on health and social care services.
While most of the UK is basking in sunshine, northwest Scotland is experiencing scattered cloud and patches of rain, according to the Met Office.
