Various factors play a role in climate change, including oceanic processes (such as ocean orbits), changes in solar radiation received from the earth, volcanic eruptions, and changes in human activity. Climate change has affected atmospheric and oceanic phenomena such as the Earth's surface temperature, precipitation, sea level, wind speed, wave height, coastlines and other phenomena and has changed these characteristics. In studying the effects of climate change on oceanic phenomena, estimating the long-term impact of climate change is of great importance. This is important because the offshore structures in these areas are affected by these changes and there is a need to amend the standard guidelines for the design of coastal structures. In this study, using the CGCM3 climate change model, wind speed values for the Persian Gulf and the Sea of Oman were extracted. These values as model input, using the third generation numerical model MIKE21 (SW) which simulates wave parameters with the least assumptions, were converted into wave characteristics and finally the amount of changes in wave characteristics such as wave height Wave period and wave direction have been obtained in the Persian Gulf, the Sea of Oman and part of the Indian Ocean that is affected by climate change in the region. The results of studies have shown that the effect of climate change on wave height and wave period is negligible, but in Makran beaches the effect of climate change on the angle of the wave direction can be considered and this will affect the sedimentation process. The effect of climate change on the wave direction and its effect on the structure should be further investigated for the construction of ports and marine structures such as desalination catchments in these areas.Various factors play a role in climate change, including oceanic processes (such as ocean orbits), changes in solar radiation received from the earth, volcanic eruptions, and changes in human activity.
