How to say "forecast" in Japanese

Choosing the right word
  • 予報よほうJLPT N3approx.Common
    noun, suru verb, transitive verbThe word for a forecast issued as a report, most familiar from weather forecasts; it presents predicted conditions as announced information rather than a personal guess.
    今夜こんやの予報よほうは雨あめである。↗
    Rain is forecast for this evening.
  • 予期よきJLPT N3approx.Common
    noun, suru verb, transitive verbCovers expecting or anticipating something in advance; as a translation of 'forecast' it is marginal, since it names the act of expecting rather than a prediction itself.
    ここでお目めに掛かかれるとは全然ぜんぜん予期よきしませんでした。↗
    I little expected to see you here.
  • 予想よそうJLPT N1approx.Common
    suru verb, transitive verb, no-adjectiveThe general-purpose word for expecting or predicting how something will turn out; when 'forecast' means a prediction of results, outcomes or trends, this is the word you want.
    あなたはどんな結果けっかを予想よそうしていますか。↗
    What results do you anticipate?
  • 予言よげんCommon
    noun, suru verb, transitive verbPrediction in the sense of declaring what will happen — prophecy or foretelling; it is not the word for forecasts of weather or similar conditions.
    君きみの予言よげんが当あたったよ。↗
    Your prophecy has come true.
  • 思惑おもわくCommon
    nounPoints to what people expect or anticipate, often others' expectations with a speculative flavor; it is seldom the word for a forecast itself.

Use 予報 for issued forecasts such as the weather, 予想 for general predictions of outcomes, 予期 for the act of expecting, 予言 for prophecy-like declarations, and 思惑 for people's speculative expectations.
