About Sardinia

Sardinia is Italy’s second-largest island, in the western Mediterranean south of Corsica. In Italy each Region sets its own bathing season and the municipalities issue bathing bans; current results for every Sardinian site are shown on the Ministry of Health’s Portale Acque.

How this page is defined: official EEA bathing waters reported by Italy whose coordinates fall inside a boundary drawn around Sardinia. Coordinates are reported by the national authority.

How to read this map: Each dot is one official bathing water, coloured by its 2025 rating. Coloured areas are the regions; region names link to their pages. Sea and large lakes are blue, neighbouring countries grey. Positions: official EEA coordinates. Boundaries: Eurostat NUTS 2024, generalised (© EuroGeographics); lakes: Natural Earth. Outlines are simplified, so a few shoreline dots can sit just offshore.

Sardinia by area

Each official site is grouped under the nearest of 12 reference towns, measured in a straight line from its reported coordinates. This is an orientation aid, not a municipal boundary.
