In a big wave wipeout, a breaking wave can push surfers down 20 to 50 feet (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. Additionally, the water pressure at a depth of 20 to 50 feet can be strong enough to rupture one's eardrums. Strong currents and water action at those depths can also slam a surfer into a reef or the ocean floor, which can result in severe injuries or even death.
