In the world, there is a general increase in sea surface temperatures with higher values reaching in enclosed seas. Türkiye is surrounded by these enclosed seas, and sea surface temperatures have been measured since the 1940s. Since most of the stations contained missing data, only 23 stations were used in the study. First of all, the distribution of sea surface temperatures was determined, and then annual and monthly trends were revealed using Mann-Kendall series correlation analysis and Sen slope value. As a result of the study, it was seen that the annual average sea surface temperatures in Fethiye, Ordu, Finike, Çanakkale, Kuşadası, Sinop, Konak and Sarıyer stations have a significant increase trend. Monthly trends show different patterns depending on the seas, with increases in the Mediterranean during the beginning of summer, in the Aegean and Marmara seas during the winter, and in the Black Sea coast during the summer. The analysis shows that the rate of increase in the Mediterranean is 0.67°C/decade and 2°C/decade in the Aegean and Marmara seas and the Black Sea coast. In the Black Sea, the increase in the average maximum sea surface temperature in June at Giresun station is 4°C/decade.
