Britons should brace themselves for the sweltering summer to continue 'until at least next week', the Met Office has warned.Temperatures in parts of England and Wales will continue to exceed 30C on Sunday and over the next few days, the forecaster said.While a risk of thunderstorms could develop in parts of the south from Monday, most areas are expected to stay dry, sunny and very hot into the coming week.The warning came amid several water firms announcing hosepipe bans and the deaths of three people who drowned after getting into difficulty in open water.London was also plunged into chaos yesterday after wildfires ripped through the shrubbery close to one of Britain's busiest train stations.Stratford station in London was evacuated and temporarily shut on Friday night as 60 firefighters and eight fire engines rushed to tackle the blazes.The Met Office recorded a provisional daily high temperature of 33C in Yelverton, Devon, on Saturday.2026 has already broken several weather records - having become the first where temperatures of 35C were recorded in the UK on six separate days.

Other offences should be reported online.Craig Snell, forecaster at the Met Office, said: 'Today, 33C is still well above average for the time of year.'The very hot conditions are going to continue across the UK until at least next week.'He added: 'During the hot weather, make sure to stay hydrated, avoid prolonged exposure to the sun and check on friends and family.'If you're planning on enjoying the seaside, check the water temperature. The water still can be quite cold so make sure you're fully aware of that to avoid cold water shocks.'Mr Snell said people should be mindful of waves on the south coast as some strong wind could develop in the coming days.Amber heat health alerts were issued by the UK Health Security Agency (UKHSA) for the West Midlands and the South West, from 9am on Sunday until 9pm on Wednesday.This means significant impacts are likely across health and social care services due to the high temperatures, including a rise in deaths, particularly among those aged 65 and over, or with health conditions.Yellow heat health alerts were posted for the East Midlands, the North West, the South East, the East of England and London, and will also be in place from 9am on Sunday until 9pm on Wednesday.The UKHSA said similar significant impacts are possible across these areas, and warned of a potential increase in water-related incidents across England, including risks from cold water shock and drowning.
