Matosinhos Beach faces possible removal from the official list of bathing waters after persistent water pollution and associated public‑health risks. The beach was closed 18 times during the last bathing season; the Portuguese Environment Agency (APA) is awaiting the adoption of remedial measures and a final decision is expected in April. Local authorities warn that failure to address contamination could cost Matosinhos its bathing‑area designation and further restrict public access.
