The lenght of time a wave has traveled or in more intelligent words The Fetch of a wave is the distance over open water over which the wind has blown (further it has travelled, the larger the wave.)

The fetch of a wave is the distance over which the wind blows without obstruction, generating waves on the water surface. A longer fetch typically results in larger and more powerful waves due to more time for the wind to transfer energy to the water. Fetch plays a critical role in wave height and energy.
The size of a wave is primarily determined by the speed and duration of the wind that generates it. Additionally, the fetch, which is the distance over water that the wind blows in a continuous direction, also influences wave size. The longer the fetch and stronger the wind, the larger the waves produced.
The height of a wind-formed wave can be affected by factors such as wind speed, duration, and fetch (distance over which the wind has blown). Stronger winds over longer distances (fetch) can create larger waves, while shorter fetch or shorter duration of wind may result in smaller waves. The interaction between wind and the ocean surface also plays a role in wave height.
The height of a wave is the vertical distance between the wave's crest and trough. It is typically measured in meters, from peak to trough. The height of a wave can vary depending on factors such as wind speed, duration, and fetch.
The three main factors that affect the size of a wave are the speed and duration of the wind that creates the wave, the distance over which the wind blows (known as the fetch), and the depth of the water.
Wind speed, wind duration, and the distance over which the wind blows (fetch) can all affect the size of a wave.
