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 July–September; July scores 9.7/10 with highs of 27 °C, sea at 23.7 °C and 3 mm of rain.
That matches the median for beaches in Italy in the same month.
At its warmest the water here is 0.5 °C cooler than the Italy median for August (25.8 °C).
Across the year the sea averages 18.8 °C, cooler than 51% of the coastal beaches in the atlas.
November is the wettest month (90 mm) and July the driest (3 mm); the yearly total is about 500 mm.
Daylight runs from 9.5 hours in December to 14.9 hours in June; in mid-July the sun rises at 06:10 and sets at 20:49 local time.
Orientation, sun and shore
The shore faces south-east (125°). Open water fills about 44% 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 240° to 301°, behind the land.
Sunrise is over the sea in every month.
Straight out to the south-east about 1,200 km of open sea lies before the next coast, enough for large swells to build. The beach is on an island of about 24,702 km².
About 1 km offshore the sea is roughly 17 m deep and 35 m at 3 km. Behind the beach the ground is about 27 m above sea level 500 m inland and 69 m at 1.5 km.
Within 1 km, the land is 62% tree cover, 19% shrubland and 12% grassland (satellite land-cover map, 2021): a largely natural setting. Water makes up 47% of that circle.
