Orientation, sun and shore

JunDecNESW

The shore faces south-south-east (155°). Open water fills about 33% of the horizon close by, which makes it an open stretch of shore.

At no time of year does the sun set over the sea here: sunset bearings run from 244° to 295°, behind the land.

Sunrise is over the sea in October–February.

Straight out to the south-south-east there is open water for more than 2,000 km, so the beach is exposed to long ocean swell.

About 1 km offshore the sea is roughly 9 m deep and 11 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 21 m above sea level 500 m inland and 167 m at 1.5 km, with hills rising behind it.

Within 1 km, the land is 47% built-up land, 39% tree cover and 7% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 35% of that circle.
