Abstract
Abstract Based on data of direct wave measurements carried out in the coastal zone of the Black Sea, the probability of the appearance of negative values of the skewness of sea-surface elevations is studied. It is shown that ensemble average probability that the skewness is less than zero is about 15%. The influence of the steepness and the inverse wave age on the probability of this event is analyzed. It was found that, most often, negative values of the skewness are observed for sloping waves at the decay stage.
