Swimming safety at Balneario El Ancla depends on current Río de la Plata water quality conditions. The river's water can be affected by sediment and urban runoff, particularly after storms. While some locals do swim, it's advisable to check water quality reports first. The balneario historically offered recreational beach activities, though facilities and monitoring may be limited compared to ocean beaches. From a security standpoint, the area is generally safe during daylight hours when other visitors are present. Always supervise children closely as lifeguard services may not be consistently available.

Visit Balneario El Ancla during weekday mornings for the least crowds, as this hidden spot attracts mainly local residents. Spring and summer months (October-March) provide the warmest weather for enjoying the riverfront, though the beach is accessible year-round. Weekends see more families, particularly during summer when people seek relief from heat. Late afternoons offer pleasant temperatures and opportunities to relax by the water. Winter visits are less common but still possible for peaceful walks along the Vicente López coast. The balneario maintains its quiet, neighborhood character regardless of season.
