The field of study covers the major urban settlements of Turkey such as Adana, Antalya, Antakya, Mersin. Agricultural
activities are also widely carried out in these areas with a high population. Also, Turkey’s southern coast has a high
tourist density throughout the year, as it hosts many of its tourist activities. Variability and change of precipitation
have the potential to affect many sectors or people. Especially, floods and overflow events experienced in recent
years have led to the loss of life and property in the region. Detection of change points is one of the most important
issues of studies to understand changes or variability of river flows and precipitation. In this study, we used the
meteorological station in the Mediterranean region (eastern coastal zone) in Turkey for the period 1965-2019. Pettitt’s,
SNHT, Buishand’s tests were applied to determine whether there was any change in the annual total precipitation
data. The years 1968, 1969, 1988, and 2006 respectively are the important change points in the data. Especially, the
year 1988 is an important change point for many stations. The annual precipitation difference before and after the
change point determined for many stations is approximately 100 mm. In the study, long-term changes and trends of
the meteorological stations in the Mediterranean coastal zone were analyzed using the Mann-Kendall test. For longterm
changes in precipitation, the early 1990s can be considered as the beginning of a significant change. Especially
in the last 10 years, very important changes have been experienced in the precipitation. Besides, the seasonality of
precipitation, which is a prominent characteristic of this region
