When to go
The beach-day index peaks in March–June; April scores 8.5/10 with highs of 25 °C, sea at 25.8 °C and 116 mm of rain.
That matches the median for beaches in Brazil in the same month.
Across the year the sea averages 23.7 °C, warmer than 74% of the coastal beaches in the atlas.
January is the wettest month (236 mm) and August the driest (46 mm); the yearly total is about 1,570 mm.
Daylight runs from 10.7 hours in June to 13.6 hours in December; in mid-April the sun rises at 06:15 and sets at 17:49 local time.
Orientation, sun and shore
The shore faces south (185°). Open water fills about 50% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in September–March; in mid-December it goes down at 18:45 local time on a bearing of 244°.
Sunrise is over the sea in October–February.
Straight out to the south 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 12 m deep and 17 m at 3 km. Behind the beach the ground is about 5 m above sea level 500 m inland and 89 m at 1.5 km.
Within 1 km, the land is 40% tree cover, 36% built-up land and 17% grassland (satellite land-cover map, 2021): a partly built-up setting. Water makes up 59% of that circle.
