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 14.0 °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 8.4 hours in December to 16.0 hours in June; in mid-August the sun rises at 07:08 and sets at 21:29 local time.
Orientation, sun and shore
The shore faces south-west (220°). Open water fills about 19% of the horizon close by, which makes it a sheltered cove or bay.
The sun sets over the sea in November–February; in mid-December it goes down at 17:22 local time on a bearing of 235°.
The opposite shore is only about 500 m away to the south-west, which keeps the water sheltered from big waves.
About 1 km offshore the sea is roughly 1 m deep and 14 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 27 m above sea level 500 m inland and 39 m at 1.5 km.
Within 1 km, the land is 36% grassland, 33% tree cover and 14% built-up land (satellite land-cover map, 2021): a mixed, lightly developed setting. Water makes up 20% of that circle.
- Grass 36%
- Tree 33%
- Built 14%
- Crop 12%
- Bare 6%
