Compound wind and precipitation extremes (CPWEs) pose significant threats to infrastructure, economies, the environment, human lives. In this study, recurrence, spatial distribution, intensity, synoptic conditions leading formation of CPWEs were assessed in eastern part Baltic Sea region. Using ERA5 reanalysis data, identified when both daily maximum speed exceeded 98th percentile thresholds on same day at grid cell. Due proximity influence terrain, most frequent windward slopes highlands western investigation area. The severe occurred second half summer early September. Based data from Hess–Brezowsky classification catalogue various datasets, during cold season (October–March) is associated with intense zonal (westerly) flow, while warm (April–September), it linked activity southern-type cyclones. number increased across all seasons, largest changes observed summer. However, majority are insignificant according Mann–Kendall test.
