County-level figures for June 2026 show widespread warmth across the UK, with mean temperatures above average in every listed county.
The Met Office’s monthly climate statistics use HadUK‑Grid data to work out county, regional and UK‑wide averages. The dataset takes weather observations from across the country and interpolates them across the UK onto a 1km x 1km grid, covering every part of the UK. Some of these records stretch all the way back to 1836, meaning almost 200 years of weather data. This blog will look at the county monthly weather stats for June 2026.
