The UK is bracing for a heatwave as the Met Office forecasts rising temperatures across the nation. Much of the country will likely experience heatwave conditions by the coming weekend, according to the National Weather Service. Warm air is building through the week, driven by high-pressure systems moving over the region.
On Wednesday, the highest temperatures in the UK are expected to reach around 27 degrees Celsius. By Thursday, this will rise to 29 degrees Celsius as the heat intensifies. Saturday will see even more locations exceed heatwave thresholds, with temperatures potentially exceeding 30 degrees Celsius in many areas. The warmest conditions are likely across London and eastern England, but heatwave conditions could spread to the Midlands and parts of east Wales.
A heatwave in the UK is officially declared when a location records at least three consecutive days with temperatures meeting or exceeding the local heatwave threshold. Across much of the north and west, this threshold is 25 degrees Celsius. However, Greater London and the Home Counties have a higher threshold at 28 degrees Celsius due to their typically warmer climate.
The Met Office has issued a yellow heat alert for most of England, effective from 8 am until 5 pm on Thursday. This alert warns of significant health impacts, including increased risks for older and vulnerable people. Temperatures are expected to spike to 31C in parts of the country during the alert period. Many places will see thermometers reach the mid-20s Celsius as well.
Tony Wisson from the Met Office stated that temperatures are likely to peak in the low 30s Celsius this weekend before easing early next week. Some forecast models even suggest temperatures could rise into the mid-30s by Monday, though this is considered a lower-likelihood scenario. High pressure is expected to move away from the UK into early next week, resulting in falling temperatures.
The unsettled start to June has given way to this warmer spell, with the Met Office predicting an increased likelihood of a hot summer in its three-month forecast. This comes after a changeable period with Atlantic frontal systems bringing showers and rain across the nation earlier in the month.
Public health officials are urging people to stay hydrated, avoid excessive sun exposure, and check on vulnerable neighbours during the heat spell. The National Health Service recommends seeking cool places during the hottest parts of the day and never leaving children or pets in parked cars.
The heatwave follows an unusually warm May saw the UK’s hottest May day on record, though that spell ended with cooler Atlantic air arriving at the end of May. The current forecast suggests summer conditions are finally arriving after the changeable early June weather.
Residents should monitor Met Office updates regularly as the situation develops, especially those with underlying health conditions. The heat is expected to last until midweek before giving way to showers, thunderstorms, and persistent rain later in the period.
