The climate crisis is increasing the likelihood of extreme heat, with the UN climate chief describing May’s heatwaves across Europe as a “brutal reminder of the spiralling impacts of the climate crisis”. Wolverson added that a combination of cloudy conditions and high humidity could make the heat feel “rather oppressive”, with a chance of thunderstorms. The Met Office reiterated its water safety advice after 16 people died in water during the May heatwave. The weather service issued a reminder that the sea is still cold at this time of year, which can cause cold-water shock at temperatures below 15C. The Met Office also encouraged people to be aware of the risk of strong currents and hidden obstacles below the water’s surface, to only swim accompanied by others, and float on their backs if they get into trouble.
