Being highly sensitive to the climatic condition, nature-based destinations will be faced with many changes due to climate change. Given this, it is essential to assess the impacts of projected climate change on tourism development in coastal destinations. Based on the application of the Physiologically Equivalent Temperature, this study investigates climatic information for the present and predicted conditions in the future to discuss the climate change impacts on tourism development. The results show this Iranian leading destination will become too hot in summer and a more pleasant destination in autumn and winter. Increasing investment in indoor facilities may become increasingly necessary for summer, and part of the demand should be moved from summer to the rest of the year.
