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 9.4/10 with highs of 26 °C, sea at 24.9 °C and 38 mm of rain.
That matches the median for beaches in Italy in the same month.
Across the year the sea averages 17.8 °C, cooler than 59% of the coastal beaches in the atlas.
November is the wettest month (110 mm) and July the driest (38 mm); the yearly total is about 900 mm.
Daylight runs from 9.0 hours in December to 15.4 hours in June; in mid-July the sun rises at 05:37 and sets at 20:45 local time.
Orientation, sun and shore
The shore faces east-north-east (70°). Open water fills about 64% of the horizon close by, which makes it an exposed spot with water on most sides.
At no time of year does the sun set over the sea here: sunset bearings run from 238° to 304°, behind the land.
Sunrise is over the sea in every month.
Straight out to the east-north-east the next coast is roughly 120 km away, so waves are mostly wind-driven sea rather than ocean swell.
About 1 km offshore the sea is roughly 11 m deep and 15 m at 3 km. Behind the beach the ground is about 323 m above sea level 500 m inland and 337 m at 1.5 km, so the beach is backed by steep slopes or cliffs.
Within 1 km, the land is 69% tree cover, 17% grassland and 8% shrubland (satellite land-cover map, 2021): a largely natural setting. Water makes up 61% of that circle.
