The recent heatwave in the UK is coming to an end as cooler temperatures and rain are forecasted starting Sunday. The peak temperature reached a record 35.1C (95.2F) in London on Tuesday, prompting health alerts and leading to at least 14 fatalities related to water incidents. As the country transitions into meteorological summer, temperatures are expected to drop significantly, with maximums ranging from 15-20C in early June. A shift in weather patterns will bring unsettled conditions, including rain and thunderstorms, particularly affecting southern and eastern England where dry conditions have persisted. The anticipated rain is welcomed by gardeners and growers, but the heatwave also caused disruptions, notably in Kent, where thousands are experiencing water supply issues due to increased demand during the hot spell. The UK Health Security Agency has issued warnings about the dangers of swimming in open water, especially for children.
