Fun in the sun is one of the constants in American life. The impulses don’t change, even if the fashions do.

In 1947, when LIFE accompanied 10,000 young men and women to Balboa Beach in Southern California for a seaside romp. This day of surf and sand took place during spring break, and was marked by dancing, boat races, beauty pageants and sunbathing. The evening hours found students aglow in the warmth of bonfires as portable radios churned out the tunes of the day. (Top hits that year included “Zip-a-Dee-Doo-Dah” and “Chi-Baba, Chi-Baba (My Bambino Go to Sleep).“)

The fashion looks tell you that you are in another era. But not much else does, really. The pleasures of the beach remain more alike than not, regardless of the age that you are in—or the age of the beachgoers, for that matter. By the seaside, people become kids again, and that’s part of the fun of being there.
