Orientation, sun and shore

JunDecNESW

The shore faces north-east (45°). Open water fills about 58% of the horizon close by, which makes it an exposed spot with water on most sides.

The sun sets over the sea in November–January; in mid-December it goes down at 15:18 local time on a bearing of 229°.

Sunrise is over the sea in March–October.

Straight out to the north-east the next coast is roughly 200 km away, so waves are mostly wind-driven sea rather than ocean swell.

About 1 km offshore the sea is roughly 6 m deep and 21 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 0 m above sea level 500 m inland and 0 m at 1.5 km, a flat coastal plain.

Within 1 km, the land is 38% built-up land, 30% tree cover and 23% grassland (satellite land-cover map, 2021): a partly built-up setting. Water makes up 43% of that circle.
