UK endures record‑breaking 2026 heatwave as temperatures top 30 °C for weeks

The United Kingdom is experiencing its third major heatwave of 2026, with a stretch of 12 consecutive days in parts of England and Wales where temperatures exceeded 30 °C. May, June and July have each recorded days above 35 °C – a first in the UK’s climate record – and a total of 25 days above 30 °C have been logged so far. The Met Office warns that the hot, dry spell will likely persist for another seven to ten days before a brief cooling later in the week, after which another surge of mid‑30 °C temperatures is forecast for the end of July.

Health officials have issued a yellow heat alert for southern England, the Midlands, the east and London, citing increased risk to vulnerable people, higher demand on health services and a rise in heat‑related incidents. The UK Health Security Agency and the UK Health Security Agency have warned of potential water‑related accidents and strain on indoor cooling.

The heatwave is also driving a surge in road traffic, with the RAC estimating that 14.1 million motorists will travel over the upcoming weekend, the busiest holiday travel period in four years. Meanwhile, across Europe, the prolonged heat has spurred a sharp rise in demand for air‑conditioning, with Chinese manufacturers such as Midea, TCL and Gree reporting sales jumps of 70 %‑300 % in countries including Germany, France, Spain and the UK.

Meteorologists note that 2026 has already delivered more days above 30 °C than the entire year of 1976, and that nighttime temperatures remain unusually high, compounding discomfort. The Met Office’s State of the UK Climate report describes the situation as “historic and unprecedented”, linking it to accelerating human‑driven climate change.
