The United Kingdom is currently experiencing its third heatwave in three months, with temperatures forecasted to surpass 35C in certain areas later this week. South east England has officially met the heatwave criteria after experiencing temperatures above 28C for three consecutive days, as confirmed by the Met Office on Monday.
The temperatures are expected to climb across the UK during the week, with more regions likely to reach their local heatwave thresholds, according to the forecaster. Parts of southern England could reach highs of around 32C on Tuesday, escalating to 33C on Wednesday, and 34C on Thursday, with isolated areas projected to hit 35C on Friday and Saturday.
On Monday, the Met Office reported the highest temperature recorded at 34C in Teddington, south-west London. While southern regions will face escalating heat from Monday evening, a north-south divide will persist in the first half of the week.
Scotland is anticipated to experience stronger winds and rain outbreaks on Tuesday, with temperatures generally aligning with seasonal averages. However, as the weekend approaches, warm air is expected to reach northern UK regions, leading to increased humidity and a heightened risk of showers or isolated thunderstorms.
The Met Office mentioned that temperatures may slightly decrease early next week, although most areas will remain warm and dry. Steven Keates, the deputy chief forecaster, advised the public to take necessary precautions against the heat and sun.
The UK Health Security Agency (UKHSA) issued amber heat health alerts for the Midlands and southern England from Wednesday to Sunday, warning of potential impacts on health and social care services. Additionally, yellow heat health alerts were issued for Yorkshire and northern England during the same period.
The UKHSA highlighted the possibility of significant impacts in these areas, including increased risks of water-related incidents. England might also experience “tropical nights” later in the week, where temperatures are not expected to drop below 20C.
National Rail Enquiries advised passengers to stay updated due to the heatwave, while vehicle breakdown rescue services are expected to be busier than usual. Drivers were urged to carry ample water, conduct essential vehicle checks, and follow safety precautions in high temperatures.
UV levels are projected to be high or very high throughout the UK during the week, prompting the recommendation to use sun protection. Additionally, pollen levels are expected to be elevated in some regions.
