Britons are being advised to follow a crucial '11am to 3pm' rule as temperatures across parts of the UK are predicted to climb to at least 29C over the bank holiday weekend. Health professionals caution that disregarding this guidance could heighten the risk of dehydration, heat exhaustion, and sunburn.
Met Office Forecast
According to the Met Office, the mercury is anticipated to rise sharply in England over the extended weekend, with forecasters expecting some of the hottest weather witnessed so far this year. These sweltering conditions are likely to attract millions outdoors to beaches, parks, and gardens.
UK Health Security Agency Guidance
As per guidance published by the UK Health Security Agency on GOV.UK, Brits should attempt to avoid direct sunlight between 11am and 3pm, when UV levels and temperatures are usually at their peak. The guidance states: 'Stay out of the sun, especially between 11am and 3pm when UV rays are strongest.' Health officials also suggest keeping physical activity to a minimum during these hours wherever feasible.
Risks of Heat Exposure
The NHS warns that heat exhaustion can rapidly escalate into heatstroke if left untreated. Heatstroke is regarded as a medical emergency and can result in confusion, seizures, or loss of consciousness in serious cases. Vulnerable groups including elderly people, infants, and those with underlying health conditions are deemed most at risk during heatwaves.
Keeping Cool at Home
Government guidance also suggests drawing curtains in sun-facing rooms and keeping windows closed during the warmest parts of the day to retain cooler air inside. Once temperatures begin falling later in the evenings, households are encouraged to open windows to boost ventilation and airflow. Research referenced by the Energy Saving Trust indicates closing blinds and curtains during daytime hours can substantially lower indoor heat levels during spells of hot weather. The organisation states preventing sunlight from entering rooms is frequently one of the most straightforward methods to keep homes cool naturally.
Stay Hydrated
Experts are also pressing people to stay hydrated throughout the weekend. According to the British Nutrition Foundation, adults should consume fluids consistently during warmer weather, even if they don't feel parched, as dehydration can develop more rapidly in elevated temperatures.
Check on Vulnerable People
The UK Health Security Agency states checking in on family members, neighbours, and vulnerable individuals during warmer weather can help avoid serious health complications.
Pet Safety
Meanwhile, pet owners are also being urged not to leave animals inside parked vehicles under any circumstances during the hot spell. According to the RSPCA, temperatures inside cars can climb sharply within minutes even when windows are left partially open.
Outlook
Forecasters suggest the warmer conditions may persist into next week across some regions if high pressure continues over the UK. Millions are consequently anticipated to take advantage of the sunshine, though experts caution that doing so safely will be crucial.
