Porto Koufo in Sithonia is Greece's largest natural harbor. The bay offers almost always calm waters, regardless of the weather offshore. The beach consists of pebbles and is relatively shallow, ideal for a peaceful swim. Surrounded by pine-covered hills, it combines natural beauty with wind protection.
Real shoreline from OpenStreetMap at a fixed scale so the diagrams are comparable with one another — the dot marks the beach.
The beach faces southwest. With northeasterly winds the air flows offshore and the water near the shore stays flat; with southwesterly winds the sea builds up waves onto the beach. The bay is naturally well sheltered — conditions often remain swimmable even on breezy days.
The shore faces southwest (230°), so all year round the sun sets within its field of view, over the water.
An estimate based on the orientation of the shore — a headland or island opposite may hide the horizon.
Yes — the water deepens gradually, making it one of the better choices for small children.
On days with northeasterly (offshore) winds or no wind at all. Thanks to the sheltered bay it is one of the safer bets in the area on windy days.
No — it is an unspoiled beach with no facilities, so bring water and shade with you.
