The technical notice made by NOAA:
The peak period identifies either the period (the time between waves) associated with the locally generated wind sea (in cases with strong local winds) or the dominant wave system (swell) that is generated elsewhere.
Note that this peak period field shows discontinuities.
These discontinuities can loosely be interpreted as swell fronts, although, in reality, many swell systems overlap at most locations and times.
