気き違ちがい日和びより

noun

fickle weather; unpredictable weather

Describes weather that changes suddenly and unpredictably, often with a nuance of being erratic or crazy. The term 気違い (crazy) is now considered a discriminatory word, so this compound may be avoided in polite contexts.

• 今日きょうは気き違ちがい日び和よりで、晴はれたと思おもったら急きゅうに雨あめが降ふり出だした。

  Today's weather is fickle; just when I thought it was sunny, it suddenly started raining.
