Sea waves: waves generated by the wind blowing at the time, and in the recent past, in the area of observation.
Swell waves: waves which have travelled into the area of observation after having been generated by previous winds in other areas. These waves may travel thousands of kilometres from their origin before dying away. There may be swell present even if the wind is calm and there are no 'sea' waves.
however, my understanding is that is called the trough, and the distance between the troughs is the swell interval. It is the same with the sea waves, and the seas are measured vertically between the top of the wave and the bottom of the trough preceeding it (Height).

swell (groundswell) what
swell (groundswell) what surfers look for - clean sets of waves generated by winds from a long way away.
seas - what you'd see looking out from perths beaches most summer afternoons, heavy local winds causing mixed up chop.very poor for boating
