In this work, on the basis of mathematical modeling, the regime characteristics of wind waves in the area of the city of Alupka (Black Sea, southern coast of Crimea) are studied. To assess the statistical characteristics of waves in the coastal zone of the study area, we used data from retrospective calculations of wind waves in the Black Sea over a long period, obtained using the SWAN spectral model. The initial wind fields are presented by data from global atmospheric re-analyses ERA-Interim and ERA5 for 1979–2019 with a spatial resolution of 0.25°. Based on statistical processing of modeling results for the study area, information was obtained on the frequency of wave elements, the duration of storm and calm situations, and extreme wave characteristics. Waves with height of 0.25 and 0.5 m have the maximum frequency. This interval accounts for 43% of all cases. Waves with a height of 1 m occur in 12% of cases, and the frequency of waves with a height of 2.5 m is 1.3%. In most cases, waves in the study area come from the southwest–south–southwest sector (total frequency of 28%) and from the southeast–east-southeast sector (total frequency of 32%). The longest storm situations occur in December–January. The minimum duration of storms is observed in June.
