When to go
The beach-day index peaks in June–September; August scores 8.0/10 with highs of 31 °C, sea at 18.7 °C and 7 mm of rain.
In August that is 0.3 points above the median of the 344 beaches in Portugal covered by this atlas.
Across the year the sea averages 16.8 °C, cooler than 65% of the coastal beaches in the atlas.
November is the wettest month (90 mm) and July the driest (5 mm); the yearly total is about 580 mm.
Daylight runs from 9.5 hours in December to 14.9 hours in June; in mid-August the sun rises at 06:50 and sets at 20:33 local time.
Orientation, sun and shore
The shore faces south-east (145°). Open water fills about 44% 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 240° to 301°, behind the land.
Sunrise is over the sea in August–April.
The opposite shore is only about 12.0 km away to the south-east, which keeps the water sheltered from big waves.
About 1 km offshore the sea is roughly 25 m deep and 4 m at 3 km. Behind the beach the ground is about 21 m above sea level 500 m inland and 33 m at 1.5 km.
Within 1 km, the land is 60% built-up land, 19% tree cover and 15% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 45% of that circle.
- Built 60%
- Tree 19%
- Grass 15%
