Temperatures across the UK reach around 35C, breaking the hottest May day record again, according to reports. The high temperatures prompt public health warnings, with authorities advising people to take precautions during the hottest conditions. Separate weather alerts also note the risk of thunderstorms alongside the heat, indicating that conditions may change during the day.

Coverage also links the extreme weather period to safety concerns beyond heat. Sources mention a series of open-water fatalities in recent days, underscoring ongoing risks for people near rivers, lakes, or other bodies of water even as hot weather increases activity outdoors.

While the articles do not detail the specific locations of the fatalities or provide new figures beyond the heat reaching 35C, they collectively describe a combination of record-breaking warmth, associated health guidance, and wider weather warnings, occurring at the same time as recent incidents involving people in open water.
