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 east (95°). Open water fills about 28% 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 east about 300 km of open sea lies before the next coast, enough for large swells to build. The beach is on an island of about 23,368 km².
About 1 km offshore the sea is roughly 13 m deep and 22 m at 3 km. Behind the beach the ground is about 6 m above sea level 500 m inland and 41 m at 1.5 km.
Within 1 km, the land is 31% tree cover, 31% shrubland and 24% grassland (satellite land-cover map, 2021): a largely natural setting. Water makes up 43% of that circle.
