The June 1976 UK heatwave saw Southampton reach 35.6°C on 28 June, equalling the then-record for June previously set in London in 1957, and included a 15-day stretch from 23 June to 7 July where temperatures hit or exceeded 32.2°C somewhere in England every day. The current June 2026 heatwave, driven by a heat dome over western Europe, is forecast to reach up to 40°C by Wednesday, close to the UK all-time high of 40.3°C recorded in July 2022. The Guardian is inviting readers who experienced the 1976 event to share memories, photographs and reflections on how they coped and how the experience differed from today’s heat.
