Climatic variations and changes occurring in glacial and interglacial periods throughout the geological history of the

world. The impact on climate agriculture and water resources, which shape every area of our lives, is very important.

Situated in a highly sensitive area of its geographical location, Turkey is affected by the variability and change. Daily

and monthly, maximum and minimum temperature values of meteorology stations located on the coasts of Aegean

Region between 1975-2018 were used. Firstly, the data were subjected to quality control (QQ). After the quality control

phase was completed, the data were subjected to homogeneity test with RH-Test. Information about the direction

and size of the trend was obtained with the Mann Kendal and Sen test, in which no distribution condition was sought

for the homogeneity-approved data set.

According to the test findings, it has been observed that there is a significant increase in the index of hot circuit time,

hot nights, hot days, summer days and tropical nights in the Aegean Region Coasts, which is one of the important

hot spot areas. Significant decreasing tendency was determined at the stations in general in cold circuit time

indicator, cool nights, cool days, daily temperature range and frosty days. Icy days index could not be calculated in

this region where maximum temperatures rarely fall below 0 °C within the specified date range. In the development

season length index, there was a significant increase only in Edremit station. When monthly maximum and

minimum temperature analyzes are evaluated; Temperature increases were more pronounced at monthly maximum

temperatures in February, April, August and September, and at monthly minimum temperatures in March, May, June,

July, August, September and November.
