The region has a typical Mediterranean climate. Summers are hot and dry, winters are warm and rainy. The winter season is very short. The frost is almost never seen and the temperature does not fall well below 5 oC.
In the peninsula; The north and south views are under different wind influences. The fact that the Datça Peninsula is under the influence of the cool (winter cold) and generally drier winds that come from the northern side of the slopes through the black waters of Kerme Bay makes these climatic conditions cooler (cooler in winter) than the southward slopes. In addition, because the steeply sloping mountain slopes receive solar energy differently, the soil water economy is also different. Thus the northern-looking slopes; Than the south-facing slopes.
As the air masses coming over the Kerme Gulf on the northern slopes of the Kocadağ mass and the Emecik mass situated in it rise, the moisture that they take from the water and the sea is transformed into a sise. For this reason Kocadağ often seems foggy. The nets it carries are heated when the air mass that has left them on the leaves of the forest in the event of fog descends from the southern slopes of the mountain. The air mass that leaves the moisture on the northern slopes and on the hill is drier as it gets warmer. Thus, on the south coast of the peninsula, the wind blows dry and warm. The winds coming from the north side are cool and the cooler as they get higher can cause snow formation in Bozdağ and ice formation.
