Description

The Ha-Ha is an early 19th-century feature located on the north side of Ha-Ha Road and Charlton Park Lane, SE18. It is a hollow that stretches across the common from east to west. The southern bank is sloped, while the northern bank is vertical and supported by a stock brick wall. The feature extends from the south-east corner of Charlton Cemetery in the west to Woolwich New Road in the east, with two breaks allowing roads to cross it.

Local climate

The Ha Ha sits in one of the driest parts of the UK, with an average of 690 mm of rain a year. This makes it drier than 98% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 98% of listed buildings.

It experiences an average of 29 freeze-thaw cycles a year, fewer than 68% of listed buildings. Of these, 12 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.
