When to go
No month reaches 5.5 on the beach-day index; the best is August at 5.3/10, held back mainly by cold water (18.6 °C) and cool air (highs of 21 °C).
Across the year the sea averages 9.9 °C, cooler than 90% of the coastal beaches in the atlas.
July is the wettest month (92 mm) and April the driest (36 mm); the yearly total is about 770 mm.
Daylight runs from 7.4 hours in December to 17.2 hours in June; in mid-August the sun rises at 05:31 and sets at 20:29 local time.
Orientation, sun and shore
The shore faces north-north-west (340°). Open water fills about 42% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in March–September; in mid-June it goes down at 21:30 local time on a bearing of 314°.
Sunrise is over the sea in June–July.
The opposite shore is only about 500 m away to the north-north-west, which keeps the water sheltered from big waves.
The sea floor is still within the shallow coastal margin 1 km out; 3 km offshore the depth is about 10 m. Behind the beach the ground is about 3 m above sea level 500 m inland and 6 m at 1.5 km, a flat coastal plain.
Within 1 km, the land is 34% tree cover, 23% built-up land and 22% grassland (satellite land-cover map, 2021): a partly built-up setting. Water makes up 13% of that circle.
- Tree 34%
- Built 23%
