The aim of this study is to investigate how the Weibull Distribution Function (WDF) is compatible with the wind data in o shore regions. Many academic studies on wind energy have been conducted. Determining potential o shore wind energy and making investments in this area have gained further signi cance today. Although many studies have been made on wind energy, o shore wind energy has received less attention. The compatibility between wind data and WDF on land has been investigated by many academic studies, and the results have been evaluated. However, the compatibility of the o shore wind data with the WDF has not been investigated su ciently and there are steps to be taken in this regard. In this study, a point was selected in Iskenderun Gulf to examine the compatibility of o shore wind data with WDF function. This study determined both the wind energy potential of the selected region and made many contributions to the literature. Six di erent methods were used to determine the parameters of the WDF and then, their performance were evaluated in di erent statistical error analysis tests.
