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 January–April; April scores 9.3/10 with highs of 27 °C, sea at 27.3 °C and 14 mm of rain.
Across the year the sea averages 28.2 °C, warmer than 91% of the coastal beaches in the atlas.
October is the wettest month (154 mm) and March the driest (13 mm); the yearly total is about 760 mm.
Daylight runs from 11.0 hours in December to 13.3 hours in June; in mid-April the sun rises at 06:08 and sets at 18:42 local time.
Orientation, sun and shore
The shore faces west (260°). Open water fills about 69% 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 19:04 local time on a bearing of 295°.
Straight out to the west about 500 km of open sea lies before the next coast, enough for large swells to build. The beach is on an island of about 196 km².
About 1 km offshore the sea is roughly 108 m deep and 191 m at 3 km, so deep water starts close to shore. Behind the beach the ground is about 0 m above sea level 500 m inland and 8 m at 1.5 km, a flat coastal plain.
Orientation from OpenStreetMap land polygons sampled in 36 directions; depths and heights from the GEBCO 2020 grid (about 450 m cells), indicative only.
Average wind speed at 10 m reaches 7.0 m/s in November, the windiest month.
OpenStreetMap shows no lifeguard station within 1 km. Seasonal lifeguard posts are often unmapped, so check on site.
