Matching surfboard to waves

Matching a surfboard to the waves is about choosing the right board for the conditions you’re surfing. Understanding how different waves influence your board choice gives you the knowledge to make a more informed decision. Choosing the right board can make the difference between a good surf session and a bad one.

Waves explained

Waves can be understood through three main elements: size, type and shape. These determine how a wave breaks and directly influence your surfboard choice.

Wave size

Wave size

The easiest and most consistent way is to measure wave height from the bottom to the top of the wave on the front face.

This differs from, for instance, the Hawaiian scale, which measures wave height differently and tends to report smaller sizes for the same waves.

Wave type

Wave shape

  • Bottom contour (seafloor shape): If the seafloor rises gradually from deep to shallow water, the wave will be mellow. If it rises quickly, the wave will be hollow.
  • Wave period: Waves with a longer period move faster and are more likely to produce hollow waves.

It comes down to how much time the wave has to move from deep to shallow water. Less time results in a hollow wave.
