Description

This is one of two late 19th century signal platforms from a former steam packet harbour. The northern platform is supported by wooden piles that are cross-braced, with angles reinforced by metal plates. It features a depth scale, a ladder leading up to the decking, and is equipped with iron bollards and railings. There are two railway-type signals mounted on lattice girder posts, each with ladders.

Originally, a floating landing stage was located at the rear of this platform and was connected to the quayside by a pivoting bridge that ran between wooden dolphins closer to the shore.

Local climate

Signal Platform in Bay sits in a wetter-than-average part of the UK, with an average of 1,080 mm of rain a year. This makes it wetter than 86% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 87% of listed buildings.

It experiences an average of 22 freeze-thaw cycles a year, fewer than 77% of listed buildings. Of these, 8 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.
