5Praia de Boa Viagem, Brazil
Situated in the city of Recife, Praia de Boa Viagem is a popular beach in Brazil that has experienced a concerning rise in shark attacks over the past few decades.
The construction of a nearby port disrupted the sharks’ natural migration patterns, bringing them closer to shore. Despite the danger, tourists still flock to this beautiful beach, although local authorities warn against swimming far from the shore.
