South Aegean Sea has important climatologic changes due to its geographical position, the size and the distance of the islands from the closest coasts of the mainland. The islands of the Aegean Sea can be differentiated into three groups with similar climatic data:
North Cyclades (Kythnos, Kea, Andros, Tinos)
All the islands have mild Mediterranean climate, which in the SE areas tends to be sea climate. The winter is very mild, with average temperature that in many islands of the Cyclades is over 120 C. During summer the average temperature is over 250 C in most of the islands, the atmosphere is still cool though due to the winds and the sea.br>
The climatic conditions of the area of the South Cyclades are characterized as favorable for agricultural production. The free of frost period of the year, very important for many plants, is exceptionally large and it lasts from March the 1st till November the 15th, i.e. for 260 days per year. A limiting factor of the production and generally of the agricultural evolution of the island is the extended dry period with low annual average height of rain that ascends to 371,7 mm (for the period 1989-1996).
