Hottest May day ever recorded in UK as temperatures continue to rise The United Kingdom has recorded its hottest May day ever, with temperatures still climbing and forecasters warning that further rises are possible. According to the Met Office, temperatures reached 33.5°C at Heathrow, surpassing the previous May record of 32.8°C set in 1922 and matched in 1944. The extreme heat has been driven by a strong area of high pressure over northwestern Europe, combined with hot air moving in from Africa. Meteorologists said the heatwave is not yet over, with temperatures expected to peak at around 35°C in some parts of England and the south-east before gradually easing later in the week. Many regions across England, including London, Essex, Suffolk, and Oxfordshire, have already met official heatwave criteria, with temperatures exceeding regional thresholds for several consecutive days. Sunday night also brought unusually warm conditions, with parts of London recording overnight temperatures close to tropical levels, making it difficult for many people to sleep. Health authorities have issued amber heat-health alerts, warning of increased risks to older adults, young children, and people with underlying health conditions. Hospitals and emergency services have been placed on heightened alert as the heat continues. Public services have also reported pressure from the conditions, including increased water demand and transport-related disruptions. Authorities have urged people to stay hydrated, avoid prolonged exposure to the sun during peak hours, and check on vulnerable individuals. Experts say the UK’s rising temperature records reflect a broader trend of intensifying heatwaves linked to climate change, with extreme summer-like conditions now appearing earlier in the year than in previous decades. The Met Office said further updates will be issued as the heatwave develops and conditions evolve across the country.
