When to go
The beach-day index peaks in June–September; September scores 9.5/10 with highs of 28 °C, sea at 25.0 °C and 29 mm of rain.
In September that is 0.3 points above the median of the 415 beaches in Greece covered by this atlas.
Across the year the sea averages 19.8 °C, warmer than 61% of the coastal beaches in the atlas.
December is the wettest month (86 mm) and August the driest (8 mm); the yearly total is about 500 mm.
Daylight runs from 9.6 hours in December to 14.8 hours in June; in mid-September the sun rises at 07:05 and sets at 19:35 local time.
Orientation, sun and shore
The shore faces south-west (230°). Open water fills about 36% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in August–April; in mid-December it goes down at 17:07 local time on a bearing of 241°.
Straight out to the south-west 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 15 m deep and 44 m at 3 km. Behind the beach the ground is about 24 m above sea level 500 m inland and 52 m at 1.5 km.
Within 1 km, the land is 89% built-up land, 6% tree cover and 3% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 46% of that circle.
- Built 89%
- Tree 6%
- Grass 3%
