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 and April–August; June scores 9.1/10 with highs of 25 °C, sea at 22.8 °C and 37 mm of rain.
In June that is 1.2 points above the median of the 659 beaches in Brazil covered by this atlas.
At its warmest the water here is 1.7 °C cooler than the Brazil median for March (26.6 °C).
Across the year the sea averages 23.1 °C, warmer than 71% of the coastal beaches in the atlas.
December is the wettest month (198 mm) and August the driest (35 mm); the yearly total is about 1,180 mm.
Daylight runs from 10.8 hours in June to 13.5 hours in December; in mid-June the sun rises at 06:25 and sets at 17:09 local time.
Orientation, sun and shore
The shore faces north (5°). Open water fills about 72% 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 17:09 local time on a bearing of 295°.
Sunrise is over the sea in every month.
Straight out to the north the next coast is roughly 30 km away, so waves are mostly wind-driven sea rather than ocean swell.
About 1 km offshore the sea is roughly 26 m deep and 32 m at 3 km. Behind the beach the ground is about 38 m above sea level 500 m inland and 35 m at 1.5 km.
Within 1 km, the land is 68% tree cover, 25% built-up land and 6% grassland (satellite land-cover map, 2021): a partly built-up setting. Water makes up 59% of that circle.
