Abstract The Bohai Sea, located at the edge of western Pacific, is one most vulnerable regions under climate change. Using high‐precision MIKE three‐dimensional hydrodynamic numerical model, this study conducted comparative experiments to investigate impacts atmospheric pressure, wind, specific volume, and evaporation precipitation runoff on seasonal variations sea surface height (SSH) in Sea. findings reveal that average annual SSH Sea lower northeast higher southwest, summer winter. Moreover, variation decreases from north south, with exceeding 0.4 m northern Liaodong Bay but only 0.2 southern Laizhou Bay. Atmospheric pressure emerges as a significant factor, contributing 72.7%, 73.9%, 71.0%, 92.0% changes Bay, Strait, respectively, causing difference approximately 0.22 areas. Specific volume contribute 6.1%, 21.7%, 19.3%, 4.0% respective regions. Wind direction result during winter summer, while part exhibits opposite trend. This evaluates contribution each factor changes, provides reference for other areas, which improves accuracy engineering design non‐period water level forecasts, potential affecting marine environments.
