When to go
The beach-day index peaks in July–August; August scores 6.9/10 with highs of 24 °C, sea at 18.3 °C and 50 mm of rain.
In August that is 1.1 points below the median of the 625 beaches in France covered by this atlas.
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 13.9 °C, cooler than 77% of the coastal beaches in the atlas.
December is the wettest month (95 mm) and September the driest (41 mm); the yearly total is about 790 mm.
Daylight runs from 8.5 hours in December to 16.0 hours in June; in mid-August the sun rises at 07:07 and sets at 21:28 local time.
Orientation, sun and shore
The shore faces east (97°). Open water fills about 42% 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 235° to 307°, behind the land.
Sunrise is over the sea in March–October.
The opposite shore is only about 500 m away to the east, which keeps the water sheltered from big waves.
About 1 km offshore the sea is roughly 8 m deep, a shallow, gently shelving sea floor. Behind the beach the ground is about 17 m above sea level 500 m inland and 25 m at 1.5 km.
Within 1 km, the land is 43% built-up land, 42% tree cover and 10% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 37% of that circle.
- Built 43%
- Tree 42%
- Grass 10%
