Long-term monthly averages: air from NASA POWER (2001–2020), sea from NOAA OISST (1991–2020); records are the extremes of 2001–2020. How the index works.
When to go
The beach-day index peaks in February–May and November; April scores 8.6/10 with highs of 26 °C, sea at 25.8 °C and 98 mm of rain.
In April that is 0.3 points above the median of the 659 beaches in Brazil covered by this atlas.
Across the year the sea averages 23.7 °C, warmer than 73% of the coastal beaches in the atlas.
January is the wettest month (212 mm) and August the driest (42 mm); the yearly total is about 1,370 mm.
Daylight runs from 10.7 hours in June to 13.6 hours in December; in mid-April the sun rises at 06:20 and sets at 17:53 local time.
Orientation, sun and shore
The shore faces south-east (145°). Open water fills about 33% 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 244° to 295°, behind the land.
Sunrise is over the sea in September–March.
Straight out to the south-east 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 4 m deep and 10 m at 3 km, a shallow, gently shelving sea floor. Behind the beach the ground is about 0 m above sea level 500 m inland and 6 m at 1.5 km, a flat coastal plain.
Within 1 km, the land is 70% built-up land, 12% mangroves and 8% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 32% of that circle.
- Built 70%
- Mangrove 12%
- Grass 8%
- Tree 6%
- Bare 3%
