When to go
No month reaches 5.5 on the beach-day index; the best is August at 5.2/10, held back mainly by cool air (highs of 20 °C) and cold water (18.3 °C).
At its warmest the water here is 3.8 °C cooler than the France median for August (22.1 °C).
Across the year the sea averages 12.7 °C, cooler than 81% of the coastal beaches in the atlas.
December is the wettest month (92 mm) and April the driest (43 mm); the yearly total is about 800 mm.
Daylight runs from 8.1 hours in December to 16.3 hours in June; in mid-August the sun rises at 06:44 and sets at 21:16 local time.
Orientation, sun and shore
The shore faces north-north-west (330°). Open water fills about 47% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in February–October; in mid-June it goes down at 22:05 local time on a bearing of 309°.
Sunrise is over the sea in June–July.
Straight out to the north-north-west 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 7 m deep and 8 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 12 m above sea level 500 m inland and 8 m at 1.5 km, a flat coastal plain.
Within 1 km, the land is 66% built-up land, 15% tree cover and 11% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 58% of that circle.
- Built 66%
- Tree 15%
- Grass 11%
- Bare 8%
