Many Brazilian beachgoers traditionally jump over seven waves on New Year's Eve for good luck.
The practice is especially associated with coastal celebrations, including the famous gathering at Copacabana Beach in Rio de Janeiro. Participants often make a wish or express an intention while jumping over each wave, linking the ritual to hopes for prosperity and protection in the coming year.
The number seven has significance in the tradition and is also connected with Afro-Brazilian religious customs, particularly reverence for Iemanjá, a sea-associated figure. People may wear white clothing and offer flowers, although practices vary among participants and communities.
Not every Brazilian celebrates in exactly the same way, and the wave ritual is not a formal national requirement. The fireworks, white clothing, and beach gatherings are related customs, but seven waves is the specific number associated with this luck ritual.
