The United Kingdom recorded its hottest day in 17 years, as temperatures reached 36.4 degrees Celsius in south-east England, the Met Office said.
Earlier, a high of 26.4 degrees Celsius was recorded in Wales, 23.5 degrees Celsius in Scotland, and 20.9 degrees Celsius in Northern Ireland.
Due to the warm weather, thousands of people flocked to the British coast on Friday.
Bournemouth, Christchurch and Poole Council’s beach check app showed 19 of its 24 beaches under red alert, warning people to avoid the areas as safe social distancing is not possible.
The remaining beaches were under amber, meaning they were congested and beachgoers should “stay alert”.
Last week, the Met Office warned that climate change driven by industrial society is having an increasing impact on the UK’s weather.
Its annual UK report confirmed that 2019 was the 12th warmest year in a series from 1884, and described the year as remarkable for high-temperature records in the UK.
