Due to the importance of tide in coastal areas, it is necessary to study this issue . The different global and regional models have been introduced. Among these models, FES2014 model was considered for study due to its efficiency. Several study stations of the Persian Gulf including open coast areas, Khuran region and northern areas of Khure-mousa were studied. The reason for choosing these areas was the importance and special conditions of these areas. The goal is to evaluate the FES2014 global tidal model in the Persian Gulf, especially in certain areas.For this purpose, water level time series were predicted by tidal components of FES2014 model. Finally, the model was compared with the results obtained from the analysis of observations using the IOS harmonic method. The investigations conducted on the Pilot, Emam and Mahshahr stations showed that the further it was moved from the pilot station to the interior of Khure-mousa and Emam station, the conformity of the observations and predictions of the FES2014 model becomes less. As far as the Mahshahr station is concerned, due to the lack of model components, it is not possible to extract. In the comparison of the RMSE results of Rajaei and Basaeedu stations, the values of 0.09 meters and 0.11 meters were closer to zero, of course, it should be kept in mind that factors, the observation period, the quality of the observed data, the location of the stations, and the accuracy of the model have an effect on these results. The components of FES2014 model were compared with the components of TMD model and harmonics resulting from the analysis by IOS method from the observations of tide gauges. This model does not have the necessary validity and accuracy in certain areas such as Khuran and Khure-mousa compared to the open coast areas.
