Overview
- The Met Office extended amber 'extreme heat' warnings to run from Monday to Thursday, covering large parts of southern and eastern England and sections of Wales.
- Forecasters predict widespread daytime highs of 35–38°C and consecutive 'tropical nights' near or above 20°C that will reduce overnight cooling and worsen heat stress.
- The UK Health Security Agency, NHS, HSE and RNLI have issued heat‑health alerts and guidance urging hydration, altered working practices, and strict water‑safety precautions such as the RNLI's 'Float to Live' advice.
- Officials warn the heat could disrupt transport, energy and water services and raise demand on health and social care, with a higher risk of open‑water incidents after multiple May fatalities.
- Scientists say a heat‑doming high pressure is the weather driver and that human‑caused warming has made such events more likely, though forecasters note uncertainty about how long the hottest conditions will persist and say warnings may be updated if thunder or cooler Atlantic air arrives.
