Forecasting is used in various professional and social sectors, due to the need to
eliminate risk when making decisions for future activities. Forecasts are a key
methodological tool for any future development and decision, with their quality
depending on the way in which the data were generated and analyzed. Prediction
remains an estimation method, an estimate which, due to various unbalanced and
unknown parameters, contains a finite error rate. The seasonal component is a cyclical
fluctuation with a period of one year, as within this period all the upward and downward
movements are exhausted. The seasonal variation comes from the fact that the data are
related to the seasons, with the values they receive being related to the climatic
differences between the seasons. The causes of the seasonality of tourism are mainly
due to climatic and geographical characteristics of an area and a complex of
institutional, economic, political and social characteristics of the countries of tourist
origin and tourist destination, with tourist arrivals and revenues of Greek tourism over
time record the highest prices the third quarter of a year (July - August - September)
and the lowest in the first quarter of each year (January - February - March). The
purpose of this work is a first brief presentation of the situation of Greek tourism and
their seasonality, the collection, ranking, analysis and presentation of tourist data,
through tourist arrivals at airports, the islands of Rhodes, Kos and South Aegean islands
(Astypalea, Kalymnos, Karpathos, Kasos and Kastelorizo) and finally, through
methodological tools and practical linear and seasonal forecasts, the forecast of future
tourist arrivals in the aforementioned islands
