OBJECTIVES: To prevent skin cancer, the general population is recommended to limit time in the sun, to wear clothes and to seek shade around noon. This study aimed to investigate the number of beachgoers, the duration of sun exposure, and clothing worn during the day on a beach in Copenhagen.

STUDY DESIGN: Observational, descriptive study.

METHODS: On 11 beach days in 2014 and 2015, beachgoers were counted every hour from 8:00 to 20:00. It was noted if they wore clothes or swimwear. To estimate the duration of sun exposure, it was noted how long cars were parked by the beach.

RESULTS: Of the counted beachgoers 46% were present from noon to 15:00. The number of beachgoers peaked at 15:00 on weekend days (Saturdays and Sunday) and at 16:00 on working days (Monday to Friday). Both on weekend days and working days, the percentage of beachgoers wearing clothes was lowest at 13:00 when about 90% wore only swimwear. Cars were parked for 117 min on average. Around noon, the mean time expanded to 142 min. We assume this to reflect the duration of a beach visit.

CONCLUSION: The results indicate a weak tendency to limit time in the sun and to seek shade when the ultraviolet radiation is strongest in the midday sun. Hopefully information about actual sun behaviour can be used to adjust campaigns.
