Swimming is prohibited on Tuesday, 25 August 2026, at five beaches in Bizkaia According to the Cruz Roja Bizkaia the red flag is flying at Las Arenas, Toña, San Antonio, Isuntza and Karraspio. Swimming is prohibited there. Access to the water is currently permitted at the territory’s other beaches. The situation update was published in the morning.
The classification is based on the lifeguard service’s daily safety assessment. A red flag indicates a general swimming ban due to dangerous conditions. The notice did not specify the causes; depending on the stretch of beach, these typically include strong currents, heavy surf or other immediate risks to swimmers. On sections that are not closed, the flag may be green (swimming permitted) or yellow (swim with caution), depending on the lifeguards’ assessment.
Today’s order is part of the usual seasonal adjustments to flag statuses along the coast of Bizkaia on the Cantabrian Sea. During the summer months, lifeguard services update their advice at short intervals to reflect changing sea and wind conditions. Conditions can change during the day as wave heights, currents or visibility worsen or improve. The current assessment is published centrally by Cruz Roja Bizkaia and displayed on site on the flagpoles in the lifeguarded areas.
Operationally, the decision on which flags to display rests with the lifeguard teams at supervised beaches; they continually assess the situation and can close or reopen sections. Municipal authorities are responsible for enforcing the orders and may take regulatory action in the event of breaches. Lifeguards point out that ignoring a red flag significantly increases personal risk.
Visitors should check the flag status on site, follow the instructions of the lifeguards, swim only in supervised areas, and take particular care with children and inexperienced swimmers. As the information was published in the morning and conditions may change, it is advisable to check the status again during the day or choose an open stretch of beach elsewhere in Bizkaia. The information given about the affected beaches and general swimming conditions comes from the latest situation update by Cruz Roja Bizkaia and was reported on Tuesday by Europa Press .
