Waste discharges into the ocean area from human activities have increased in recent years. This will affect the quality of the coastal environment. The deterioration of this environment has effects on the attractiveness of beaches and the quality of bathing water. The southeastern part of Côte d'Ivoire, and more specifically the beach area between Azuretti and Grand-Bassam, is facing this reality. This work aims to understand the state of beach quality and bathing water in the atlantic Ocean along the coastline between Azuretti and Grand-Bassam. The method used consisted of measuring the physicochemical parameters of the water with a Hanna-type multiparameter, and taking water samples to determine BOD5 and bacteriological parameters. Macro-waste was identified on the various foreshores. Sediment samples were collected to study their particle size. Five stations were visited. The variation in the values of the physicochemical parameters is between 9.05 and 9.4 for pH; 29.7 and 32.92 for salinity; 23.03 and 25.24 g/l for TDS; 30.04 and 30.52 °C for temperature; 46.08 and 50.47 ms/cm for conductivity and between 3 and 5 mg/l O2 for BOD5. Escherichia coli and Salmonella were not determined in ocean waters. Total coliforms and enterococci were identified with levels ranging from 6200 to 45000 CFU/100 ml and from 00 to 930 CFU/100 ml, respectively. The waters of stations 1; 4 and 5 would be unsuitable for all leisure activities and water sports. Plastics, plants, pieces of wood, and paper and cardboard are the most abundant macro-waste on the beach. The sediments at the various foreshore stations consist largely of medium-grained sand. Very fine sand is less abundant.
