The dataset provides data on beachgoers' behaviours, attitudes and perceptions of coastal bathing risks at La Lette-Blanche beach (France). Data were collected from a face-to-face quantitative survey conducted during the lifeguard-patrolled summer period (July-August) 2022 from a sample of 722 visitors. The survey was conducted in French or English and consisted of 40 questions covering four main topics: (1) attitudes toward risk in general and concerns about risks in everyday life, including leisure and water based recreation context; (2) risk experience (participation in beach activities in general, visits at southwest France beaches, recreational activities, previous accidents); (3) visits to La Lette-Blanche beach at the time of the survey (attractiveness, bathing behaviour and perception of risks); (4) sources of information and preventive behaviours related to bathing risks. Individual socio-demographic characteristics were collected at the beginning of the survey. Individual informations are completed with environmental data (collected by a nearby directional wave buoy, tide gauge and weather station). Additionnaly, an hourly estimate of rip current hazard, shore break wave hazard and of the total beach crowd during the patrolling hours was provided by the chief lifeguard of the study beach. The dataset contains 133 variables and 722 observations.
