Overview
- Provisional Met Office figures published Tuesday confirm the June–August mean temperature was 16.5°C, the highest in the UK record going back to 1884.
- A rapid Met Office attribution study found human greenhouse‑gas emissions made a summer like 2026 about 130 times more likely, shifting its return period from roughly one in over 1,000 years to about one in nine years.
- The season produced five distinct heatwaves that drove widespread impacts including drought declarations, rising wildfire counts and travel disruption.
- Health and mortality data show severe human costs with the UK Health Security Agency estimating 2,877 heat‑associated deaths in England linked to the May–June heatwaves.
- Operational responses remain active with multiple hosepipe bans, low reservoir storage in England at about 60% of average, weekly National Drought Group coordination and targeted government support for farmers.
