A breaking wave can push surfers down 6.2 m to 15.5 m below the surface. Once they stop spinning around, they have to quickly regain their equilibrium and figure out which way is up. Surfers may have less than 20 seconds to get to the surface before the next wave hits them.

Surfing
Surfing is a surface water sport in which the wave rider, referred to as a surfer, rides on the forward or deep face of a moving wave, which is usually carrying the surfer towards the shore.
