UK June temperatures may breach 39°C, narrowing gap to all-time record

The Met Office forecasts 39°C in June 2026—nearly 3.5°C above the previous June peak of 35.6°C. This compresses the distance to the national all-time record (37.8°C, July 2022) to just 1.4°C. Infrastructure standards, built on pre-2022 assumptions, now face strain. A Red Extreme Heat Warning is active; record-breaking temperatures are highly likely across England and Wales.
