In Japan, 2,000 to 3,000 drowning accidents occur every season at major bathing beaches. To prevent drowning accidents, beachgoers themselves need to be aware of the dangers of the ocean and avoid them. As a way to do this, bathing beaches provide daily risk levels regarding swimming conditions to beachgoers using beach safety flags in three colors. We have constructed an AI model that can predict the probability of drowning accidents with high accuracy and developed a new method for objectively judging swimming conditions based on the prediction results. On the other hand, when the AI model was applied to two beaches located on the east and west sides of the pocket beach, the prediction accuracy was low. This study quantitatively analyzed the reasons for the lower prediction accuracy for three beaches located on the Onjuku beach. As a result, it was considered that the reason for the low accuracy was that topographical features were not taken into account.
