When to go
The beach-day index peaks in June–September; July scores 9.6/10 with highs of 29 °C, sea at 24.2 °C and 7 mm of rain.
That matches the median for beaches in Greece in the same month.
At its warmest the water here is 0.5 °C cooler than the Greece median for August (25.6 °C).
Across the year the sea averages 19.2 °C, warmer than 56% of the coastal beaches in the atlas.
December is the wettest month (94 mm) and August the driest (5 mm); the yearly total is about 490 mm.
Daylight runs from 9.6 hours in December to 14.8 hours in June; in mid-July the sun rises at 06:12 and sets at 20:46 local time.
Orientation, sun and shore
The shore faces north-east (35°). Open water fills about 22% of the horizon close by, which makes it a sheltered cove or bay.
At no time of year does the sun set over the sea here: sunset bearings run from 241° to 301°, behind the land.
Sunrise is over the sea in May–August.
Straight out to the north-east the next coast is roughly 20 km away, so waves are mostly wind-driven sea rather than ocean swell.
About 1 km offshore the sea is roughly 17 m deep and 50 m at 3 km. Behind the beach the ground is about 68 m above sea level 500 m inland and 92 m at 1.5 km, so the beach is backed by steep slopes or cliffs.
Within 1 km, the land is 68% tree cover, 13% shrubland and 12% grassland (satellite land-cover map, 2021): a largely natural setting. Water makes up 39% of that circle.
- Tree 68%
- Shrub 13%
