Blue Flag Beaches in Portugal

Portugal's Blue Flag Coastline

Portugal's 398 Blue Flag certified beaches represent one of Europe's most closely monitored bathing water regimes. Its 17 distinct coastal regions each offer different conditions — from sheltered inlets to exposed open-water beaches. Sites are assessed by ABAE in partnership with the Foundation for Environmental Education (FEE), which administers the global Blue Flag programme across more than 50 countries.

The Blue Flag is awarded each spring for the coming beach season and can be revoked at any point if standards fall below the mandatory threshold. This annual cycle means the certified list changes year to year — beaches are added as standards improve and removed when they do not meet the criteria. The guides on Zeach are updated at the start of each season to reflect the current certified list, with water quality data sourced from official EEA assessments.
