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 June–September; July scores 9.5/10 with highs of 32 °C, sea at 24.6 °C and 16 mm of rain.
That matches the median for beaches in Greece in the same month.
Across the year the sea averages 20.1 °C, warmer than 62% of the coastal beaches in the atlas.
December is the wettest month (121 mm) and August the driest (13 mm); the yearly total is about 720 mm.
Daylight runs from 9.6 hours in December to 14.8 hours in June; in mid-July the sun rises at 06:25 and sets at 20:58 local time.
Orientation, sun and shore
The shore faces south (170°). Open water fills about 42% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in December–January; in mid-December it goes down at 17:18 local time on a bearing of 241°.
Sunrise is over the sea in October–February.
Straight out to the south 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 410 km².
About 1 km offshore the sea is roughly 14 m deep and 30 m at 3 km. Behind the beach the ground is about 9 m above sea level 500 m inland and 21 m at 1.5 km.
Within 1 km, the land is 45% grassland, 23% tree cover and 23% built-up land (satellite land-cover map, 2021): a partly built-up setting. Water makes up 47% of that circle.
