USAGE:
More formal and literary than 晴(は)れ (clear weather, everyday). Common in weather forecasts, written descriptions, and the well-known proverb 青天(せいてん)の霹靂(へきれき) (a bolt from the blue — note: this uses the kanji 青(せい), not 晴(せい)). 晴天(せいてん) is a noun and does not inflect.

  • 晴天(せいてん)が続(つづ)く: fine weather continues
  • 晴天(せいてん)の日(ひ): a clear day
