Most of the sharks in Puerto Vallarta are not aggressive towards humans, but there have been a few instances of shark attacks in the area. In 2018, a tourist was killed by a bull shark while swimming off the coast of Puerto Vallarta.
To avoid a shark encounter while swimming in Puerto Vallarta, it is important to:
* Avoid swimming in areas where there are known to be sharks.
* Avoid swimming at dusk or dawn, when sharks are most active.
* Avoid swimming in murky water, where sharks cannot see you.
* Do not wear shiny jewelry or clothing, which can attract sharks.
* Do not spearfish or feed fish, which can attract sharks.
If you see a shark, stay calm and swim slowly and smoothly away. Do not make sudden movements, which could startle the shark.
