Big wave surfing: how they prepare

Big wave surfing at spots like Nazaré in Portugal, Jaws in Maui or Mavericks in California represents the extreme end of the sport: waves that can exceed 20 metres in height and water weights that can plunge a surfer dozens of metres deep in seconds. The difference between a big wave surfer and a conventional one is not just courage but specific physical and mental preparation that no amount of conventional surfing can replace.

The most critical training component is apnoea. A surfer caught by a big wave can be held underwater for two or more wave sets, which can equal two to three minutes without oxygen while the body is under the physical stress of the whitewater and pressure. Elite surfers work with apnoea coaches until they can hold their breath for four to six minutes at rest and two to three under stress. That threshold does not eliminate the danger but provides the margin to avoid panicking and allow the inflation vest to do its job.

Complementary physical preparation includes swimming in extreme surf conditions, functional strength training to resist the current when escaping a wave, and simulation of emergency situations with water safety teams. Jet ski rescue teams are part of the system: they not only assist in emergencies but allow the surfer to be towed to the peaks of the largest waves that conventional paddling could not reach. The combination of technology, training and safety teams transformed a sport that formerly claimed lives regularly into a high-risk but manageable activity for those who prepare professionally.
