Marine storms reaching the Romanian coast occur with a relatively high frequency. The Black Sea offshore area is characterized by an active storm regime, especially in the northern sector. The northern sector storms have the highest frequency during winter, when the reported values of wind speed ​​reach as much as 40 m/s. Against the backdrop of the wind speed values and the direction from the northern and southern sector, the offshore waves can reach values ​​of 5-8 m and even more. The frequency of storm surges in the Black Sea is relatively low as compared to other European seas, but the occurrence of such storms causes important damage. Due to the magnitude of sea level rise induced by the storms, the sea level is 7-8 times higher than the changes occurring for the sea level, due to other factors. In a bid to highlight the effect of storm surges with long return periods reported for the area of ​​the western shore of the Black Sea, a study was carried, focusing on the variation of the water level on the coast. Consequently, variations of up to 1.3 m have been revealed, which stood above the average level. As part of the present assessment, the return periods were calculated in order to determine the extreme conditions required in the case of numerical modeling applications of marine hydrodynamic processes. Such processes will be used in a complex study of marine meteorological processes with convertible energy potential for the Romanian coast area.
