The study is aimed to identify the average for the 12-year monitoring period characteristics of the wind field seasonal variability from measurements with high temporal discreteness. This increased the accuracy of wind characteristic meters during synchronous studies of near-water wind and coastal current variations near the Southern Coast of Crimea. The mean annual characteristics of the coastal wind in the near-water layer of the atmosphere and their seasonal variability were identified by analysing the materials of the database of in situ measurements made in 2012-2023 during a complex experiment from the stationary oceanographic platform offshore at Cape Kikineiz. The selected wind characteristics near the coast were compared with the known climate wind characteristics in the region. In the seasonal range of spectral characteristics variability, wind fluctuations at periods of seasonal harmonics I-IV and VI were identified. The energy peak of fluctuations at seasonal harmonic VI was statistically significant both in the wind spectra and coastal current. In the other parts of the spectra, significant differences in the energy distributions of seasonal atmospheric and hydrospheric variations were obvious. Synchronous time series of vector characteristics of coastal wind and current variability were processed using identical information technology. In the intra-annual range of wind variability, we revealed the contribution of the monsoon component as well as seasonal fluctuations of the coastal wind directed along the mountain ridge slope. The range of variability of the studied wind characteristics at sea near Cape Kikineiz was obviously consistent with the characteristics of the regional wind field on land, identified at meteorological stations of the Southern Coast of Crimea. The presented results are necessary for comprehensive studies of the interannual variability of the regional wind field in order to assess statistical relationships with certain variability of the coastal current.
