When to go
No month reaches 5.5 on the beach-day index; the best is August at 5.0/10, held back mainly by cool air (highs of 20 °C) and cold water (18.5 °C).
Across the year the sea averages 9.7 °C, cooler than 90% of the coastal beaches in the atlas.
August is the wettest month (76 mm) and April the driest (35 mm); the yearly total is about 680 mm.
Daylight runs from 7.4 hours in December to 17.2 hours in June; in mid-August the sun rises at 05:52 and sets at 20:51 local time.
Orientation, sun and shore
The shore faces north-north-east (20°). 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 June–July; in mid-June it goes down at 21:52 local time on a bearing of 314°.
Sunrise is over the sea in March–September.
Straight out to the north-north-east the next coast is roughly 80 km away, so waves are mostly wind-driven sea rather than ocean swell.
About 1 km offshore the sea is roughly 10 m deep and 15 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 9 m above sea level 500 m inland and 28 m at 1.5 km.
Within 1 km, the land is 38% grassland, 35% cropland and 13% built-up land (satellite land-cover map, 2021): a rural setting among farmland. Water makes up 61% of that circle.
