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 9.3/10 with highs of 25 °C, sea at 23.6 °C and 26 mm of rain.
That matches the median for beaches in Turkey in the same month.
At its warmest the water here is 0.6 °C cooler than the Turkey median for August (25.0 °C).
Across the year the sea averages 15.9 °C, cooler than 69% of the coastal beaches in the atlas.
December is the wettest month (106 mm) and August the driest (23 mm); the yearly total is about 720 mm.
Daylight runs from 9.3 hours in December to 15.1 hours in June; in mid-July the sun rises at 05:45 and sets at 20:37 local time.
Orientation, sun and shore
The shore faces south-west (215°). Open water fills about 33% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in October–March; in mid-December it goes down at 17:38 local time on a bearing of 239°.
Straight out to the south-west the next coast is roughly 80 km away, so waves are mostly wind-driven sea rather than ocean swell.
About 1 km offshore the sea is roughly 13 m deep and 24 m at 3 km. Behind the beach the ground is about 13 m above sea level 500 m inland and 88 m at 1.5 km.
Within 1 km, the land is 85% built-up land, 9% tree cover and 3% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 45% of that circle.
