Local climate

Milestone sits in one of the wettest parts of the UK, with an average of 1,600 mm of rain a year. This makes it wetter than 99% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 99% of listed buildings.

It experiences an average of 1 freeze-thaw cycle a year, fewer than 99% of listed buildings. Of these, 1 follows at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.2°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
