Swimming is permitted on Tuesday, 18 August 2026, at most beaches in the province of Bizkaia . The only exception is Playa de Toña, which was marked with a red flag in the morning, according to Cruz Roja Bizkaia . Swimming is therefore prohibited there; at the other coastal areas it is either unrestricted or permitted with caution.
The warning system used by the lifeguards remains unchanged: green means swimming is permitted, yellow advises extra caution, and red prohibits entering the water. According to the latest update for Bizkaia, green flags predominate; a few beaches have yellow flags, which can indicate currents, waves or poor visibility. The lifeguards responsible at each location decide the flag status and change it if conditions shift.
Cruz Roja Bizkaia published the flag-status information on Tuesday morning. Regional media such as Europa Press and 20minutos carried the report and confirmed that Toña was the only beach closed with a red flag that day, while swimming remained permitted at the other beaches in the territory.
The cited notices initially gave no detailed reasons for the closure at Playa de Toña. Common causes of red flags include strong currents, high waves, thunderstorms near the beach, visibility problems, contamination warnings or medical incidents. Without official clarification, it remains unclear which factor prompted the decision. Flags may change during the day depending on the weather, waves and currents; lifeguards update the information regularly.
For the Basque Country The key message for the day is clear: swimming is permitted in Bizkaia apart from at Toña, in many places without restrictions and in some with a yellow flag advising caution. Cruz Roja Bizkaia regularly reminds beachgoers to follow barriers and lifeguards’ instructions, and to enter the water only in supervised areas. The status reported today applies to Tuesday, 18 August 2026; it may change later and local services will announce any updates.
