When to go
The beach-day index peaks in July–August; August scores 9.5/10 with highs of 31 °C, sea at 23.0 °C and 21 mm of rain.
In August that is 1.5 points above the median of the 625 beaches in France covered by this atlas.
At its warmest the water here is 0.9 °C warmer than the France median for August (22.1 °C).
Across the year the sea averages 17.3 °C, cooler than 62% of the coastal beaches in the atlas.
November is the wettest month (94 mm) and July the driest (13 mm); the yearly total is about 560 mm.
Daylight runs from 9.0 hours in December to 15.4 hours in June; in mid-August the sun rises at 06:42 and sets at 20:43 local time.
Orientation, sun and shore
The shore faces south-south-west (195°). Open water fills about 28% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in November–January; in mid-December it goes down at 17:03 local time on a bearing of 238°.
Straight out to the south-south-west about 500 km of open sea lies before the next coast, enough for large swells to build.
About 1 km offshore the sea is roughly 23 m deep and 74 m at 3 km. Behind the beach the ground is about 46 m above sea level 500 m inland and 95 m at 1.5 km.
Within 1 km, the land is 55% built-up land, 34% tree cover and 7% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 29% of that circle.
- Built 55%
- Tree 34%
