Knowledge about statistics for water level variations along the coast due to storm surge is important utilization of coastal zone. An open and freely available hindcast archive covering Norway adjacent sea areas spanning time period 1979–2022 presented. The model forced by wind stress mean pressure taken from non-hydrostatic NORA3 atmospheric hindcast. A dataset consisting observations more than 90 gauges coasts North Sea Norwegian compiled quality controlled, used assess performance observational distributed in both space, when considering all controlled data, comparison with modeled levels yield a absolute error (MAE) 9.7 cm root square (RMSE) 12.4 cm. Values MAE RMSE scaled standard deviation observed each station are 0.42 0.54 deviations, respectively. When geographical differences characteristics different countries/regions, values range 5.7–13.9 7.6–17.8 respectively, 0.33–0.46 0.42–0.59 deviations values. minimum maximum −2.60 m 3.92 m. In addition, 100-year return estimates calculated hindcast, of, −2.75 3.98 All found southern area.
