Four years data of temperature from the coastal areas of Santos and Cananeia are analysed in continuation of part I of this work. Earlier tidal wave theories for coastal areas and some basic processes on the determination of Nz are summarized. Seasonal variations of temperature are found to obey approximately a general harmonic law of propagation with depth and from it estimates of the mean annual values of N are obtained. These estimates (preliminaries) seem to indicate that mixing at the coastal areas of Santos is smaller than in the ones of Cananéia.
