This study is restricted to days with even pressure distribution, and without strong winds that would interfere with the sea breeze. The greatest frequency of such a sea breeze occurs in May, June and October, which are the months of low frequency of the Etesians. The diurnal march of vapour pressure at Athens is clearly double in all months and the year as a whole. However, on days with uninterrupted sea breeze, mainly from May to October, three pairs of extremes characterize the variation, there being two secondary maxima and two secondary minima in the forenoon. The arrival of the moist sea breeze overcompensates the normal decrease of vapour pressure in the morning.
