Parts of the United Kingdom are expected to experience heatwave conditions, potentially surpassing temperatures in Barbados. The warmest areas could reach up to 32C, with the rest of the country gradually climbing into the high 20s later in the week.
Regions in the south and south-east of England are likely to witness heatwave temperatures starting on Saturday, June 20, extending more widely by Sunday, June 21. Moreover, southern parts of the UK might see temperatures hitting 30C by Friday, June 19.
The Met Office defines a heatwave as three consecutive days with daily maximum temperatures meeting or exceeding specific thresholds. These thresholds vary across regions, with values between 25C and 28C in different parts of the country.
Compared to Barbados, where temperatures are set to range between 26C and 30C on Sunday, certain areas in the south and south-east of England could experience even hotter weather, potentially reaching 33C on Monday.
Despite the high temperatures, intermittent rain is expected, especially in northern and western areas, along with a possibility of thunderstorms in the south-east. A yellow heat health alert has been issued for various regions by the UK Health Security Agency, indicating an increased risk to vulnerable individuals and a rise in water-related incidents.
Gregory Wolverson, deputy chief forecaster at the Met Office, highlighted the contrasting weather patterns expected in the UK this week. While unsettled conditions are projected in the north-west, southern and eastern regions will experience rising temperatures. He emphasized the likelihood of heatwave conditions in many parts of southern and eastern England, although not necessarily accompanied by clear skies due to increased cloud cover. Thunderstorms may develop, bringing heavy showers and localized impacts.
The Met Office advised caution for individuals heading to the coast, noting that sea-surface temperatures are not as warm as during midsummer. Notably, water safety concerns have been raised following several deaths in open water during the previous hot spell in late May and early June.
