5. Recife, Brazil

Recife, a popular coastal city in Brazil, is known for its beautiful beaches and warm climate. Unfortunately, it also has a high incidence of shark attacks. The Recife metro area has seen numerous attacks over the years, resulting in several fatalities.
Piedade Beach, in particular, is notorious for shark activity. Beachgoers are advised to heed the warning signs posted along the shore.
The construction of Port Suape, located a short distance from Boa Viagem Beach, is often cited as a contributing factor to the increased shark presence. Activities in this area have disrupted local ecosystems, attracting more sharks to the coastline.
