When to go
The beach-day index peaks in July–August; August scores 7.7/10 with highs of 25 °C, sea at 18.1 °C and 22 mm of rain.
That matches the median for beaches in Portugal in the same month.
At its warmest the water here is 0.8 °C cooler than the Portugal median for August (18.9 °C).
Across the year the sea averages 16.0 °C, cooler than 68% of the coastal beaches in the atlas.
January is the wettest month (138 mm) and July the driest (13 mm); the yearly total is about 1,010 mm.
Daylight runs from 9.3 hours in December to 15.1 hours in June; in mid-August the sun rises at 06:44 and sets at 20:35 local time.
Orientation, sun and shore
The shore faces west (280°). Open water fills about 53% of the horizon close by, which makes it an exposed spot with water on most sides.
The sun sets over the sea in every month; in mid-June it goes down at 21:06 local time on a bearing of 302°.
Straight out to the west there is open water for more than 2,000 km, so the beach is exposed to long ocean swell.
About 1 km offshore the sea is roughly 8 m deep and 14 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 1 m above sea level 500 m inland and 2 m at 1.5 km, a flat coastal plain.
Within 1 km, the land is 36% bare ground, sand or rock, 34% built-up land and 23% grassland (satellite land-cover map, 2021): a partly built-up setting. Water makes up 73% of that circle.
- Bare 36%
- Built 34%
- Grass 23%
- Tree 6%
