Water Quality

Water quality classification 2020 per Decreto-Lei 135/09 (amended by Decreto-Lei 113/2012). Low contamination risk based on water quality history. No days of bathing prohibition or advice against bathing due to short-term pollution events in the 2020 bathing season.

Risks

Cyanobacteria, macroalgae, and phytoplankton proliferation are all unlikely.
