💧 Bathing water quality: excellent (official assessment by the Greek Ministry of Environment, 2025 — monitoring point “Sounio”, 470 m from the beach)
Sounio beach combines swimming with a unique view of the Temple of Poseidon. The sandy shore stretches beneath the archaeological site, offering a distinctive setting. The bay has moderate natural protection, while the beach's orientation ensures a sunset over the temple. An ideal choice for combining history and sea.
Real shoreline from OpenStreetMap at a fixed scale so the diagrams are comparable with one another — the dot marks the beach.
The beach faces south. With northerly winds the air flows offshore and the water near the shore stays flat; with southerly winds the sea builds up waves onto the beach. The shape of the coastline offers partial shelter, cutting down part of the swell.
The shore faces south (190°), so from October to February the sun sets within its field of view, over the water. In the remaining seasons the sunset falls further to the side, over land.
An estimate based on the orientation of the shore — a headland or island opposite may hide the horizon.
In calm seas yes, but the water gets deep fairly quickly — normal supervision applies.
On days with northerly (offshore) winds or no wind at all. Check the live score on Beach Radar before you go — it updates all day.
Yes — sunbeds, umbrellas and food options operate during the summer season.
