How long should you snorkel for?

What happens if snorkel goes underwater?
Unlike scuba diving where you have your own air supply, snorkels don't let you breathe while you are fully submerged in the water. The breathing tube can fill up if it dips below the water's surface, for example, a wave splashing over you, or if you dive underwater to get a closer look at marine life.

Waves also influence the ease and safety of getting in and out of the waters.
