When to go
The beach-day index peaks in July–August; July scores 9.5/10 with highs of 28 °C, sea at 23.2 °C and 24 mm of rain.
In July that is 0.4 points above the median of the 156 beaches in Turkey covered by this atlas.
At its warmest the water here is 0.9 °C cooler than the Turkey median for August (25.0 °C).
Across the year the sea averages 15.7 °C, cooler than 69% of the coastal beaches in the atlas.
December is the wettest month (90 mm) and July the driest (24 mm); the yearly total is about 680 mm.
Daylight runs from 9.3 hours in December to 15.1 hours in June; in mid-July the sun rises at 05:43 and sets at 20:35 local time.
Orientation, sun and shore
The shore faces south-south-west (200°). Open water fills about 47% of the horizon close by, which makes it an open stretch of shore.
The sun sets over the sea in September–April; in mid-December it goes down at 17:36 local time on a bearing of 239°.
Sunrise is over the sea in December–January.
Straight out to the south-south-west the next coast is roughly 30 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 25 m at 3 km. Behind the beach the ground is about 14 m above sea level 500 m inland and 47 m at 1.5 km.
Within 1 km, the land is 70% built-up land, 23% tree cover and 6% grassland (satellite land-cover map, 2021): an urban beach. Water makes up 57% of that circle.
