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–August; July scores 9.6/10 with highs of 26 °C, sea at 23.8 °C and 9 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 18.4 °C, cooler than 55% of the coastal beaches in the atlas.
November is the wettest month (100 mm) and July the driest (9 mm); the yearly total is about 610 mm.
Daylight runs from 9.3 hours in December to 15.1 hours in June; in mid-July the sun rises at 06:01 and sets at 20:52 local time.
Orientation, sun and shore
The shore faces north-east (40°). Open water fills about 47% 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 239° to 302°, behind the land.
Sunrise is over the sea in every month.
Straight out to the north-east the next coast is roughly 200 km away, so waves are mostly wind-driven sea rather than ocean swell. The beach is on an island of about 23,411 km².
About 1 km offshore the sea is roughly 11 m deep and 17 m at 3 km. Behind the beach the ground is about 44 m above sea level 500 m inland and 61 m at 1.5 km.
Within 1 km, the land is 38% shrubland, 30% grassland and 22% tree cover (satellite land-cover map, 2021): a largely natural setting. Water makes up 53% of that circle.
