To determine a wind state observation period in which annual wind state can be highly accurately predicted.SOLUTION: A wind state observation period determination support apparatus 100 comprises: a similarity calculation unit 113 which calculates the similarity between annual wind state prediction data (prediction data 130) in a target place where a wind state is predicted and wind state prediction data (prediction data 130) in a wind state observation period shorter than a year in the target place; and a wind state observation period determination unit 114 which outputs the wind state observation period in which the similarity becomes maximum. The wind state prediction data is, for example, the occurrence frequency distribution of a wind speed, the occurrence frequency distributions of both the wind speed and wind direction or the average wind speed.SELECTED DRAWING: Figure 1 【課題】高精度に年間風況予測を可能にする風況観測期間を決定する。【解決手段】風況観測期間決定支援装置１００は、風況を予測する対象地における年間の風況予測データ（予測データ１３０）と、前記対象地における年間より短期の風況観測期間の風況予測データ（予測データ１３０）との類似度を算出する類似度算出部１１３と、前記類似度が最大となる風況観測期間を出力する風況観測期間決定部１１４を備える。風況予測データは、例えば、風速の出現頻度分布、風速と風向双方の出現頻度分布、または、平均風速である。【選択図】図１
