This is a chronometer-shaped sundial supported by a life-sized lead figure of a putto. The sundial is made of brass and sits on a circular slate plinth with a rendered columnar base that is approximately 0.50 meters high.

Local climate

Chronometer Sundial sits in one of the wettest parts of the UK, with an average of 1,490 mm of rain a year. This makes it wetter than 98% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 97% of listed buildings.

It experiences an average of 32 freeze-thaw cycles a year, fewer than 60% of listed buildings. Of these, 15 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°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.
