Abstract: Climate change will have a tremendous effect on tourism activities. Tourism revenue plays a crucial role in the Turkish economy; therefore, it is vital to assess the impacts of climate change on tourism. This research aims to investigate the effects of climate change on seaside tourism on the Black Sea region in Türkiye. The summer simmer index (SSI) was utilized to determine the climatic comfort conditions in the summer months. Meteorological data, over 30 years, was used to observe the impact of climate change. Mann–Kendall trend analysis and Şen’s innovative trend analysis were applied to reveal the trends. As a result, SSI zones were computed as zones 1, 2, 3, and 4. Zone 4 was rarely observed. Thermal comfort conditions in the summer were found to not pose a health threat to tourists. Both trend methods determined an upward trend of SSI scores in Akçakoca, Samsun, Rize, and Hopa. These destinations are becoming more favorable in terms of seaside tourism due to climate change. The results of this study can be used for destination marketing. Tourism decision makers may benefit from these results for developing coastal tourism in this region.
