Wind decreases instead of stopping completely
This complicates our simple view: The wind may not stop completely at the end of the fetch, it may only weaken or change direction. As we end the section on wind waves, therefore, we see that we can have waves that seem like wind waves because they exist in a windy region, but they are actually swell that are traveling faster than the wind and therefore are not really affected by the wind.  They may, if fact,  already be taking on swell characteristics.
